Peptides Explained, Part Two: BPC-157, TB-500, and the Growth Hormone Stack

Part one covered the fight. This one covers the food.

Four peptides get walked through one at a time. BPC–157 and TB–500 are the recovery pair — the ones most often discussed together, and the ones most often sold together. The claim is that one improves the conditions for healing by supporting blood flow and collagen production, while the other helps repair cells reach the damage faster. Neither is a painkiller. Neither creates healing. The pitch is that they make the body better at a job it already knows how to do.

Getting there means a detour through inflammation, which turns out to be the wrong villain. Inflammation is the opening move in every repair your body has ever completed. The problem isn’t that it happens — it’s when it won’t leave. Then the conversation shifts to the other end of the shelf: the growth hormone stack, what a secretagogue actually does, and why IGF–1 has a longer-acting cousin that bodybuilders care about.

Running underneath all of it: the reason a peptide can’t do anything for someone who sleeps five hours and eats eighty grams of protein a day.

Nothing in this episode is medical advice. Recorded early August 2026, while the FDA’s final decision was still pending.

The show

Pete Wright: Last week we promised a war, and we delivered. The FDA, RFK, renegade scientists, the secret list, the whole circus. But here’s a second question, and it’s the one you would ask about anything before you put it in your body: what does it actually do?

So we’re back for peptides part two. And remember, peptides are a category. It’s not a thing, it’s a menu — and last week we covered whether the restaurant should even be allowed to stay open. This week we sit down and actually read the menu, item by item. Srdjan is walking me down the list one at a time, and for each one I want the same three things. What does it claim to do? Who’s selling that dream? And how much of it is actually real?

Fair warning, same as last time: nothing here is a prescription, nothing here is a shopping list. The answer to “should I try this” still lives in your doctor’s office, not in that DM from that one guy named Chad. I’m Pete Wright, he’s Srdjan Injac, and this is Build for Health.

Okay, we’re back. We’re here, and you are fired up.

Srdjan Injac: Yes, because these are the two peptides that I’m actually considering taking. So I’m going to have to consult with my doctor next week and we’ll see where we go from there. But one way or the other, I’m going to try these two and see where it goes, because there have been a lot of good results and I’ve heard people talk about it. I definitely want to try it, and I’ll let you guys know how it goes.

Pete Wright: Okay.

Srdjan Injac: But like I always do, I do extensive research and find out what it does. So I’m going to explain it to you guys.

Pete Wright: Excellent. So we’re going to start with these big two today then, right? We’re not going to do the whole list. The big two, and we’ll see what we have time for. Maybe there is a future conversation, but for today, these are the ones you are most interested in. Where do you want to start?

Srdjan Injac: Yeah, I want to explain to people what these two do when it comes to recovery, because injuries are very common. So these two are responsible for the recovery. One is called BPC-157, and the other one is TB-500. So this is like a stack — these two work together. They’re very well known. When they prescribe them, they usually prescribe these two together. So I’m going to explain each one of them and let you know how they actually work together, how well, and why.

So the first one is the BPC-157. One of the ways that this peptide helps is by improving the blood flow to the injured tissue. When you injure a tendon, ligament, or muscle, that area needs oxygen, nutrients, amino acids, and immune cells in order to begin to repair itself. Those supplies all travel through your bloodstream. BPC-157 helps those areas by forming tiny new blood vessels. Think of it like building new roads to a construction site — the better the roads, the easier it is to deliver the workers and the building materials where they need to go.

It also helps with regulating the inflammation. Now, inflammation is not the enemy. It’s actually the first step in healing. The problem is when the inflammation sticks around too long or becomes excessive.

One thing that you need to understand about inflammation — and I’m sure a lot of people don’t know about this — when you get injured, the inflammation is like an emergency response. It brings immune cells to the injured area to remove the damaged tissue, kills bacteria if there is an infection, and it signals the body that repairs need to begin. Without the inflammation, the healing wouldn’t even get started. Think of it like firefighters responding to a house fire. The problem is if those firefighters never leave. Imagine the fire is out, but they keep spraying water on—

Pete Wright: Yeah, yeah.

Srdjan Injac: —on the house for like weeks.

Pete Wright: Those are chronic. Chronic firefighters.

Srdjan Injac: Exactly. Exactly. So eventually they start causing more damage.

Pete Wright: Right. They’re the worst.

Srdjan Injac: And that’s what chronic inflammation can do. Instead of allowing the body to move into the rebuilding phase, it keeps the tissue stuck in that cleanup mode.

Pete Wright: Yeah.

Srdjan Injac: So when the inflammation lasts too long, the body continues to release inflammatory chemicals that can break down healthy tissue, slow down the collagen production, and interfere with the cells responsible for rebuilding. The blood vessels may also stay more swollen and leaky than they need to be, which can contribute to ongoing pain and swelling.

So healing happens in stages. First comes inflammation, then tissue repair, and finally remodeling, where the new tissue becomes stronger and more organized. That’s what the inflammation does. I didn’t know if many people knew that.

Pete Wright: Okay. Well, I’m glad. It’s like a fever, right? You get a fever, and the fever is itself trying to do something for an infection or for sickness, right?

Srdjan Injac: Yeah, I think that’s a good idea.

Pete Wright: It’s the same thing.

Srdjan Injac: Exactly.

Pete Wright: But it does seem like every time we think of inflammation right now, we think of it in terms of that chronic state. Like, you live with inflammation, you probably eat too much gluten, whatever.

Srdjan Injac: Yes.

Pete Wright: But in this case, it seems like we’re talking about inflammation that could be useful.

Srdjan Injac: Yes. At the beginning. You just don’t want it to stay there for too long.

Pete Wright: Yeah.

Srdjan Injac: That’s when it becomes a problem.

Pete Wright: Right.

Srdjan Injac: But if it’s there for a little bit, let the body do its own thing. So what BPC-157 also helps do is keep the inflammatory response more balanced, allowing your body to move from that cleanup phase into the rebuilding phase more efficiently.

Another reason people are interested in BPC is because it supports the cells responsible for producing collagen. Collagen is the main structural protein that gives tendons, ligaments, skin, and many other tissues their strength. I also say you can think of collagen like the steel cables in a suspension bridge — if those cables are damaged, the bridge becomes weak. During healing, your body has to manufacture that new collagen to rebuild that structure.

So the key to understanding what that peptide is: it isn’t like taking a painkiller that simply masks the symptoms. The idea is that it may help your body repair damaged tissue more efficiently. It’s not creating healing out of thin air. It may simply improve the conditions your body needs to do what it already knows how to do and what needs to be done.

Pete Wright: I’m trying to figure out that metaphor. Is it like adding a turbocharger? Is it — you know what, one of the things you keep saying is “it may do this.” And I know there is evidence out there to support what it does.

Srdjan Injac: Yeah, that’s pretty much what it does. That’s the idea of this peptide — what it’s supposed to do.

Pete Wright: All right.

Srdjan Injac: It creates the healthy environment for the healing.

Pete Wright: Now, because you haven’t started — I’m asking specifically about you. Do you think there’s anything about you that makes you more or less susceptible to the benefits of using this peptide?

Srdjan Injac: I think this will be very beneficial, not just for my forearm. Right now, I mean, my bone is healed. There’s a lot of soft tissue damage, like the—

Pete Wright: Yeah.

Srdjan Injac: —you know, I haven’t strengthened it. My [unclear] is getting better and all that stuff, but there is a lot of those micro tears in the soft tissue that this could help. But then also I injured my shoulder, and the shoulder is not getting any better. I’ve been doing all the physical therapy and all that stuff.

Pete Wright: In the same accident, yeah.

Srdjan Injac: In the same accident, yeah. It’s just, I wanted to take care of my arm first before the shoulder, but—

Pete Wright: Yeah.

Srdjan Injac: —I’ve been doing a lot of therapy for the shoulder itself and it’s not really helping. It’s not inflamed, there’s no inflammation there, but I could definitely benefit from this, and that’s the reason why I’m actually taking this.

Pete Wright: Okay.

Srdjan Injac: If the physical therapy did its own thing, I wouldn’t consider using it, but—

Pete Wright: Okay.

Srdjan Injac: —I want to see how much this is going to speed up the recovery.

Pete Wright: Okay. And the number on that one again was the 157, right?

Srdjan Injac: 157. The BPC-157.

Pete Wright: BPC-157.

Srdjan Injac: Now the other one that comes with that one is TB-500.

Pete Wright: Okay.

Srdjan Injac: So that’s another peptide that’s become popular in the world of injury recovery, especially among athletes. If BPC-157 is like a project manager directing the repair team, think of TB-500 as the transportation manager. Its job is to help the right workers get to the construction site faster and move around more efficiently once they arrive. That’s why they work together well.

It’s based on a naturally occurring protein in your body. This protein is found in many tissues and becomes more active when you’re injured. It plays an important role in wound healing by helping cells migrate to damaged tissue. That’s important, because when you tear a muscle, strain a tendon, or injure a ligament, your body has to send repair cells to that exact location before healing can begin.

So TB-500 helps make that whole process more efficient. It improves the movement of the repair cells into injured tissue, allowing the body to begin rebuilding sooner. It helps the body transition from cleaning up the damage to actually repairing it. So they appear to work through different pathways, those two. By combining them, the idea is that BPC-157 helps create the better healing environment by supporting the blood flow and collagen repair, while TB-500 helps the body’s repair cells get where they need to go and improves overall tissue remodeling.

Pete Wright: Mm-hmm. Okay. So you’ve been doing a lot of reading about this, right?

Srdjan Injac: I am. Oh yes.

Pete Wright: You’re a little bit obsessive about it, if I do say so.

Srdjan Injac: Oh yeah, yes I am.

Pete Wright: Yeah. So what do you expect in terms of results? Because I can imagine somebody listening, like me — I’m listening to you talk right now, and I’m wondering what you expect in terms of the sort of timeline of results, which may not even be a fair question. But how do you know it’s going to be having an effect? Do you know what you expect from when you start taking it to the point you’ll start feeling some relief?

Srdjan Injac: Well, I’m going to start feeling relief a lot faster. I’ve hurt my shoulder numerous times and I know—

Pete Wright: Months ago.

Srdjan Injac: Yeah, months ago. And I’ve hurt my shoulder before, and I know how long it takes to repair and to get back to where I can do all my workouts and stuff like that without pain or any kind of discomfort. So I know shoulders and I know shoulder pain, and I’ll be able to tell if my shoulder is actually repairing a lot faster, or if it’s going the same pace, or if I really feel any difference from before, when I did my own—

Pete Wright: Yeah, I mean, I—

Srdjan Injac: —recovery when I hurt my shoulder. So it’s not a good thing.

Pete Wright: It’s funny, I asked that question, and it’s almost like your shoulder is literally not improving right now. So any improvement after you start taking this stuff is probably an improvement that we can chalk up to—

Srdjan Injac: Yes, because I keep testing every week.

Pete Wright: —a peptide introduction.

Srdjan Injac: I keep trying to do different things and I’m like, it still hurts—

Pete Wright: Yeah.

Srdjan Injac: —exactly like it did the week before, and the week before that. It’s not getting any better. The weight is the same. Everything is exactly the same. It’s not even like, all right, I can pull a little bit more, or it doesn’t hurt that much, or I just feel discomfort but not a lot of pain. No. The pain is always there, it’s always the same. And I’ve been doing all the physical therapy, and I’ve been massaging it, and I’ve been—

Pete Wright: Yeah.

Srdjan Injac: —putting ice and heat and all this other stuff that I would usually do in this case. But it’s just not helping. It’s not recovering.

Pete Wright: Okay.

Srdjan Injac: So.

Pete Wright: Do you have any sense, for those who are curious, what these things cost?

Srdjan Injac: I don’t know. I’m very curious to see how much they cost. I think it depends on where you’re getting them. If you’re getting them on some random website and you’re meeting with some random doctor on that website and discussing it with him, I don’t know how much they would charge you.

Pete Wright: Yeah.

Srdjan Injac: But I’m sure it’s different if you go through your normal, regular doctor and he prescribes it through the compounding pharmacy — how much they’re going to charge you.

Pete Wright: Yeah.

Srdjan Injac: They might charge you a little bit more because it’s more pure. You know where it’s coming from.

Pete Wright: You get the good stuff, man.

Srdjan Injac: You know. Get the good stuff.

Pete Wright: Yeah.

Srdjan Injac: You know it’s going to work. You know what you’re putting in your body. When you’re getting it from a random company or website, even though you’re meeting with a doctor, you don’t know exactly how pure that is, if it’s going to be that effective or not.

Pete Wright: Yeah.

Srdjan Injac: You’re going to be putting amino acids into yourself, so you’re going to be fine, but how effective is it going to be?

Pete Wright: Yeah.

Srdjan Injac: You don’t know. So people have been getting them from different websites, and I’m sure they’re all different prices, because they’re trying to compete with each other.

Pete Wright: It just seems sketchy. I mean, just self-sourcing seems risky on this stuff.

Srdjan Injac: Yes. [unclear] Yeah, I’m going to have to do a lot of research on that too.

Pete Wright: Yeah.

Srdjan Injac: So I might have a better idea maybe when we do another episode — let people know what I found.

Pete Wright: Yeah. All right. So these two are the primary ones for rebuilding, which is obviously your interest. But can you give us a sketch of what’s left on that list that you’re curious about, even though you’re not looking to start them right away?

Srdjan Injac: I don’t know if I would — I might try this. I’m kind of curious now that I did more research and found all that stuff. I’m like, ooh. It’s very tempting. I’m like, I want to do this.

Pete Wright: Yeah.

Srdjan Injac: Because they’re all peptides, they’re amino acids, so it’s not really — I’m not putting steroids in my body.

Pete Wright: Yeah. Right.

Srdjan Injac: Once you find out what they do, it’s kind of tempting to try it, because you still have to go to a gym, you still have to work out, you still have to put in all the work. It’s not like — many people spend hundreds of thousands of dollars on these peptides while still sleeping five hours a night and eating maybe eighty grams of protein a day.

Pete Wright: Yeah.

Srdjan Injac: And that’s like hiring the best construction crew in the world but never delivering any building materials to the job site. So sleep, nutrition, training — you still need to do all this stuff. It’s not going to work otherwise. It’s not like a pill you take and it’s there and you just grow. So that’s why, while I’m still putting in all this work, I want to try it.

Pete Wright: Yeah.

Srdjan Injac: I want to see if it’s going to help speed up the muscle growth and stuff like that.

There’s another stack that’s very popular in the fitness industry, the bodybuilding industry. One is called CJC-1295 and the other is ipamorelin. Those two, when you put them together, work well, just like the two for the recovery. What one does is send the message: hey, release the growth hormone. It sends the message to your body. And the other one makes that particular gland that releases that growth hormone more responsive to that message. So that’s how those two work together.

Pete Wright: Okay.

Srdjan Injac: And that’s a very popular stack that’s used for the increase of the natural growth hormone. They’re paired because they stimulate the growth hormone through two different pathways.

Pete Wright: Okay. Okay. I don’t know why those things suddenly make me — yeah, suddenly we’re talking about stuff that makes me feel like we’re messing with the primary forces of nature here.

Srdjan Injac: And I love it.

Pete Wright: I mean, it’s great. I can smell in myself just a little bit of curiosity, some interest to see how that works.

Srdjan Injac: Yeah, give me a month and we’re going to do another episode. I’m going to tell you all the stuff that I’ve tried and used and all that stuff.

Pete Wright: Yeah. Welcome to the candy shop.

Srdjan Injac: Yes, this is my candy shop. This is my favorite shop.

Pete Wright: Oh my gosh.

Srdjan Injac: But it just sends the signal to your body to, hey—

Pete Wright: Okay.

Srdjan Injac: —produce a little bit more of what you’re already producing. It’s just, when you start aging, you’re producing less of that stuff.

Pete Wright: Yeah.

Srdjan Injac: These peptides just send a message like, hey, produce a little bit more. And then the other one sends another message like, hey, that message was there. Do it. So your body’s producing the same stuff it produced when you were in your twenties and thirties. It’s just producing a little less now.

Pete Wright: Yeah.

Srdjan Injac: So that’s all it does. And that’s why it’s safer than injecting a steroid into yourself just to get the muscle growth. I would never do that.

Pete Wright: Yeah.

Srdjan Injac: So the first one, the CJC-1295, signals your brain to release more of your body’s own natural growth hormone, helping increase the growth hormone pulses that your body already produces. If that one sends the message that it’s time to release the growth hormone, the other one makes sure that the message gets through. It helps your pituitary gland respond by releasing another pulse of the growth hormone.

Compared to some older and other peptides, this one’s more targeted, so it’s less likely to interfere with other hormones. It does this without affecting hormones like cortisol or prolactin, which is one reason why it’s so popular.

Pete Wright: Uh-huh.

Srdjan Injac: So the increased growth hormone pulses stimulate the liver and other tissues to produce insulin-like growth factor 1 — that’s what’s known as IGF-1 — which is responsible for many of the benefits that people associate with growth hormone, including increased muscle protein synthesis, improved recovery between workouts, better collagen production for tendons and ligaments, enhanced tissue repair, increased fat utilization for energy, better sleep quality in some individuals, all that stuff.

Pete Wright: Okay. Yeah.

Srdjan Injac: Now, here’s a little bit of a twist. There’s a peptide that’s called IGF-1, but there’s also one that adds two more letters that say LR3. And you’re like, oh my god, I know, it’s so complicated with all these letters on top of everything.

Pete Wright: I know. I can’t believe I’m actually wishing a big pharmaceutical company would just start manufacturing it with a name.

Srdjan Injac: So—

Pete Wright: Who knew I would wish for that?

Srdjan Injac: Yes.

Pete Wright: It’s ridiculous. All right, go ahead.

Srdjan Injac: [unclear] It’s produced by the liver and all that stuff. The hormone, the IGF-1, is the hormone your body naturally produces in response to the growth hormone. But the other peptide that has LR3 is a different version.

Pete Wright: Yeah.

Srdjan Injac: Because it stays active in your body longer than that natural IGF-1.

Pete Wright: Oh, okay.

Srdjan Injac: So there’s IGF-1 and there’s IGF-1 LR3.

Pete Wright: LR3.

Srdjan Injac: It’s just a different version that stays active longer. So the natural IGF-1 stays in your system for like half a day, anywhere from like twelve to fifteen hours. The IGF-1 LR3, the peptide that people put in, stays anywhere from twenty to thirty hours. So what does that mean — why is this difference important?

Pete Wright: Okay.

Srdjan Injac: It means the signal to muscle tissue can last longer.

Pete Wright: Okay.

Srdjan Injac: So think of IGF-1 as turning on the sprinklers for like fifteen minutes. It waters the lawn and it shuts off after fifteen minutes. Now IGF-1 LR3 is like leaving the sprinkler on for much longer, giving the lawn more time to absorb the water. So the idea is that muscle cells are exposed to the growth signal longer.

Pete Wright: Okay.

Srdjan Injac: Although that doesn’t guarantee more muscle growth. You still have to do your workouts and progressive overload and all that stuff.

Pete Wright: You’ve got to do the work, right?

Srdjan Injac: Yes.

Pete Wright: And what is it doing if you’re not working out? Is that when it starts growing like the third arm out of your chest, or does it not do anything?

Srdjan Injac: No. It’s just not going to do anything. It doesn’t do anything. You still have to do the work. Just like with all the other peptides, it creates the environment, but you’ve got to do the work.

Pete Wright: Okay.

Srdjan Injac: And this one — that’s why the bodybuilders use it, because they already put in so much work and they stay in the gym for like an hour and they’re going hard and intense. So this does help if you do that. If you don’t, it’s really not going to do much and you’re not going to see much difference. So those are two that are really popular right now in bodybuilding, and people are using them. So I might go for that one too.

Pete Wright: Why don’t you get healthy first? Because this image of you lifting something heavy and having your arms fall off right at the bar is scary.

Srdjan Injac: Oh shit.

Pete Wright: So let’s get healthy first.

Srdjan Injac: All right, we’ll try it first with the recovery one, and then once we get the go, we might try a couple of these other ones.

Pete Wright: Yeah. All right.

Srdjan Injac: Just so I can tell listeners if it’s worth it or not.

Pete Wright: Okay. This is a service that you’re providing, right?

Srdjan Injac: Yeah, exactly.

Pete Wright: If nothing else, please let Srdjan’s life serve as a warning to others.

Srdjan Injac: I’m doing it for you guys.

Pete Wright: That’s all we ask. I can’t wait to see how this goes, man. I’m very excited to see your shoulder get better and see if you can get back to normal.

Srdjan Injac: Oh, I’m excited about that too, yeah.

Pete Wright: All right, so next week, big week. Hopefully we’ll have something new to talk about next week. We also have some listener questions starting to come back now that we’re back after our vacation.

Srdjan Injac: Yes.

Pete Wright: People are actually listening to that first episode. We’ve got a couple of vacation-related questions. We’re going to start getting to those next week.

Srdjan Injac: Yeah, if they have any questions about peptides and how they work — I try to explain this in the best possible way for you guys to understand how that works, without getting into a lot of details and medical terms and all that stuff. Just explaining it in a way that actually makes sense for you guys. But yeah, ask questions about any other peptides that you might find, because there are other ones that I didn’t mention that people use for a lot of other reasons. They also have to do with fitness and metabolism and weight loss and all that stuff. So yeah, if you have any of those questions, please let me know.

Pete Wright: We’ll send them in. The link is in the show notes to send us a question. We’d love to have you do that for a future episode upcoming.

Srdjan Injac: I think—

Pete Wright: Stay tuned. The lab is open starting next week, and Srdjan is donating his body to science. Cannot wait.

Srdjan Injac: Yes.

Pete Wright: Thank you, everybody, for downloading and listening to this show. We appreciate your time and your attention. Don’t forget, send in those questions, and please share the show with someone else that you think might be interested in these kinds of topics. This is how we grow stronger together. Thanks for listening to Build for Health. We’ll catch you next week in the gym.

SECTION 2: SPOT-CHECK LIST

1. Cleaned text: “…it’s less likely to interfere with other hormones. It does this without affecting hormones like cortisol or prolactin, which is one reason why it’s so popular.” Reason: HIGHEST PRIORITY — factual attribution. Srdjan says this immediately after describing CJC-1295, so the antecedent reads as CJC-1295. The cortisol/prolactin selectivity is ipamorelin’s documented property, not CJC-1295’s — ipamorelin was designed as a selective GHS-R1a agonist that doesn’t meaningfully raise cortisol, prolactin, or ACTH, unlike older GHRPs (GHRP-2, GHRP-6, hexarelin). Verify against tape and consider a written correction in the show notes rather than an on-air pickup.

2. Cleaned text: “This week we sit down and actually read the menu, item by item.” Reason: Raw transcript read “read the food, item by item.” Corrected to “menu” to match the metaphor Pete sets up one sentence earlier (“it’s not a thing, it’s a menu”). Confirm against tape — if he actually said “food,” it’s a cold-open flub worth a pickup.

3. Cleaned text: “So there’s IGF-1 and there’s IGF-1 LR3.” / “…that’s why the bodybuilders use it…” Reason: EDITORIAL/LEGAL FLAG, not a transcription error. IGF-1 LR3 sits in a materially different regulatory bucket from the rest of the episode’s list. BPC-157, TB-500, CJC-1295, and ipamorelin are all Category 2 substances currently in the reclassification fight covered in part one. IGF-1 LR3 is not on that reclassification list — FDA’s position is that it has no USP/NF monograph, is not a component of any approved drug, and is not on the 503A bulks list, so it can’t legally be compounded for human use at all. It’s sold only as “research use only,” and it’s WADA-prohibited. The segment discusses it alongside the others without that distinction, right next to the “candy shop” bit. Recommend a written note in the show notes drawing the line, since it’s exactly the “legal ≠ approved” teaching point from part one.

4. Cleaned text: “You’re going to be putting amino acids into yourself, so you’re going to be fine, but how effective is it going to be?” Reason: Meaning-relevant claim worth flagging. As stated, this frames purity risk as an efficacy problem only. Contaminants, wrong compounds, endotoxin, and sterility failures in gray-market vials are safety problems, not just potency problems. Consider addressing in written copy rather than an on-air correction.

5. Cleaned text: “And that’s why it’s safer than injecting a steroid into yourself just to get the muscle growth.” Reason: Comparative safety claim with no supporting human trial data for the compounds under discussion. “Safer than X” is not the same as “safe,” and the episode’s own throughline is that the human evidence is thin. Flag for a written caveat.

6. Cleaned text: “Because they’re all peptides, they’re amino acids, so it’s not really — I’m not putting steroids in my body.” Reason: Same category of claim as #5, and it directly contradicts part one’s basil-vs-nightshade framing (“it’s a peptide” tells you nothing about safety). Strong candidate for the show-notes correction — it’s a clean callback opportunity rather than a gotcha.

7. Cleaned text: “…you know, I haven’t strengthened it. My [unclear] is getting better and all that stuff…” Reason: Raw ASR read “my c my breast is getting better,” which doesn’t parse in context (forearm injury, healed bone). Likely “wrist” or “grip.” Needs a tape listen — do not guess in publication.

8. Cleaned text: “—recovery when I hurt my shoulder. So it’s not a good thing.” Reason: Genuinely ambiguous. Could be “so that’s a good test” (i.e., the shoulder is a clean baseline), or a comment that the lack of improvement isn’t good. Pete’s next line supports the “clean baseline” reading. Verify against tape.

9. Cleaned text: “Yeah, I think that’s a good idea.” Reason: Kept as transcribed, but it’s a non-sequitur response to Pete’s fever analogy. Likely “that’s a good analogy” or “that’s a good example.” Verify — this is a two-word fix that makes the exchange land.

10. Cleaned text: “Yes. [unclear] Yeah, I’m going to have to do a lot of research on that too.” Reason: Raw ASR read “So we have a lot of like the open source anything, but just uh.” Unrecoverable. Given Pete’s preceding line about self-sourcing being risky, this is probably a warning against sourcing from anywhere — worth recovering, because it’s the responsible-sourcing beat.

11. Cleaned text: “[unclear] It’s produced by the liver and all that stuff.” Reason: Raw ASR read “That we says it’s you know produced by the liver.” Opening clause unrecoverable. The rest of the sentence is intact and the meaning is clear.

12. Cleaned text: “…you still have to do your workouts and progressive overload and all that stuff.” Reason: Raw ASR read “progressive thing.” Rendered as the almost-certain intended term. Confirm.

13. Cleaned text: “…many people spend hundreds of thousands of dollars on these peptides while still sleeping five hours a night…” Reason: Likely misspeak for “hundreds or thousands of dollars.” As published it reads as an implausible figure for an individual consumer. Verify against tape.

14. Cleaned text: “The natural IGF-1 stays in your system for like half a day, anywhere from like twelve to fifteen hours. The IGF-1 LR3… stays anywhere from twenty to thirty hours.” Reason: Verified — these are the standard published figures and Srdjan has them right. One nuance if you want it for the show notes: the 12–15 hour number is for IGF-1 bound to its binding proteins; free, receptor-active IGF-1 clears in roughly 15 minutes. The LR3 modification works by reducing binding-protein affinity roughly a thousandfold. No correction needed, just available if you want to go deeper in the notes.

15. Cleaned text: “When they prescribe them, they usually prescribe these two together.” Reason: Implies routine prescribing of the BPC-157/TB-500 stack as settled practice. As of the part-one reporting, the PCAC vote was non-binding and the FDA had not issued a final decision, so these are not routinely prescribable through a 503A pharmacy. Consider a date-stamped clarification in the notes.

16. Cleaned text: “…that’s the reason why I’m actually taking this.” / “Now, because you haven’t started…” Reason: Tense conflict within the same exchange. Srdjan opens the episode saying he’ll consult his doctor next week, then uses present tense here. Pete corrects to “you haven’t started.” Worth a clean-up line in the show notes so the physician-first throughline isn’t undercut.

17. Cleaned text: “Oh shit.” Reason: Explicit language decision. Retained as spoken since it’s a genuine reaction beat. Confirm the episode’s explicit tagging, or flag for a bleep.

18. Cleaned text: “Srdjan Injac” (throughout) and “please let Srdjan’s life serve as a warning to others.” Reason: ASR rendered the name variously as “Surgeon,” “Surgeon Iñats,” and “Surgeons Life.” All normalized to the canonical spelling. Also corrected: “Iphomerylin” to “ipamorelin,” “petituary” to “pituitary,” “IGFR3” to “IGF-1 LR3,” and repeated instances of “information” to “inflammation.” Spoken numerals (“BPC one five seven,” “TB five hundred”) normalized to BPC-157 and TB-500.

19. Cleaned text: “So I might go for that one too.” Reason: A trailing fragment (“Try it’s very”) was dropped at the end of this turn as an incomplete thought. Nothing substantive appears lost, but confirm if you want it restored.

Hosted by Pete Wright and Srdjan Injac, Build for Health moves beyond gym culture to explore why muscle is critical for longevity, not just looks.
