Hey everyone, welcome to a sneak peek Ask Me Anything or AMA episode of the Drive podcast. I'm your host Peter Atia. At the end of this short episode, I'll explain how you can access the AMA episodes in full along with a ton of other membership benefits we've created. Or you can learn more now by going to peteratiamd.com forward slash subscribe. So without further delay, here's today's sneak peek of the Ask Me Anything episode. Welcome to Ask Me Anything. In today's AMA, we take on one of the most requested and most confusing topics we've ever covered, peptides. Peptides sit at the intersection of biological plausibility, clinical promise, and rampant commercialization. They're often marketed as cutting edge, regenerative therapies for everything from muscle repair and longevity to cosmetic enhancements. But the reality is that the peptide ecosystem is sprawling, poorly regulated, and filled with claims that range from legitimate to completely ungrounded. So the goal of this episode is not to promote peptides or dismiss them as a category, but to give you a framework for evaluating them. Because as you know, we love us some frameworks over here. We walk through what peptides are, what questions you should ask before putting any peptide or any drug into your body, and how to think about the strength of evidence, the safety profile, and the difference between science and marketing hype. So specifically, we're going to discuss why peptides have become such a dominant topic in the wellness and longevity culture. The differences between FDA approved peptide therapeutics and quote unquote peptides, which are what most people refer to with quotes in the biohacking world, a framework for evaluating any peptide mechanism, intended effects, safety, dosing, and alternatives. And then we're going to run our framework through a handful of examples in detail. SS31, talk about the background, the biology, and the types of conditions it has been studied for. And two, receptor activity, common claims, related FDA approved compounds in the same pathway. CJC1295, I'm going to talk about growth hormone signaling, why it has been studied in humans, what it's been studied for, and how dosing is typically approached. Of course, BPC157, no discussion on the topic would be complete without that. The origin story, the proposed mechanisms, and the nature of the animal and human evidence that's often cited. We're going to talk about the role of patents and the incentives and drug development, and why some compounds do or don't advance through formal clinical pipelines. We're going to compare peptide evidence standards to other widely discussed interventions that fall into high interest in complete data categories. And talk about how peptides are manufactured and sold in the gray market, and what the research use only designation actually means, what third party testing can evaluate, and what it doesn't capture. We'll talk about oral peptides, digested breakdown, absorptive challenges, and what we know from pharmaceutical examples. Talk about what needs to happen for peptides to become more broadly usable therapies, and where peptide therapeutics may expand in the future, and what areas of medicine might be most actively and positively benefited right now. Peter, welcome to another AMA. How are you doing? I'm doing great, man. How are you? I'm doing good. So, for today's AMA, we are going to be talking about peptides. So, peptides are a topic that we get asked about an insane amount. You see so much content on there. Even today, going through our email inbox, we had two emails asking us to talk about peptides. So, it's a topic we see over and over. And our goal with this episode is not to promote, dismiss peptides overall, but just to give people a framework and how to think about them, which is, what are peptides? Where is the science solid, weak, or non-existent, and how to evaluate the claims that people make? With this, we'll walk through a core set of questions that apply to any peptide, and we'll apply it to a variety of peptides to kind of walk through some of the most popular ones, which is whether we know there's a mechanism of action. What do we know about safety and dosing? Is there any evidence that it can be helpful in humans? How do someone compare the risks and the potential benefits? And are there any other legitimate approved solutions that are available? And then at the end, we'll also zoom out and talk about the gray market space for peptides, including how people should think about purity, sourcing, etc. And then we will truly end on the potential future of peptides and what we would need to know, what new information would have to come out to really understand where these could be promising. A lot to cover, a lot of different things we said. Anything you want people to know before we get rolling? No, I think you've covered it. I don't think there's a topic I get asked about more today and probably for the last six months than this topic. I would just add that the reason it has taken us so long to come out with this AMA is we wanted to do this justice. We don't do anything in moderation on this podcast except for moderation. There's a bar that just had to be cleared. I hope we're about to clear it for you as a listener. And it just took, I'm actually kind of afraid to ask how much time it took of our research team to help me get ready for this. So let's dive into it. Perfect. I think we got to start off with defining what are peptides? By the way, it's funny. My wife asked me this over the weekend. We were sitting there, she was asking me a peptide question and it was like we were having dinner with the whole family. And of course, naturally the eight year old and the 11 year old are like, what are peptides? And so I'm explaining to them what peptides are in anticipation of this discussion. So look, there's nothing magical here. A peptide, it gets talked about in this health and wellness space like it's something magical or new, but it's not. A peptide is a short chain of amino acids. I don't think there's a real clear definition of what constitutes a peptide versus a protein. Really once you're into the thousands of peptides, you're clearly talking about proteins. I would say I've read definitions that would suggest up to 60, up to 100, I don't know, but the point is it's pretty small. So a short number, relatively short number of amino acids strung together forms a peptide. Now by the way, sometimes it's so short that it's literally just a straight line of amino acids and other times they form more complex structures, they form rings and things like that. These are things that the body naturally produces. So there are many peptides that are produced naturally. They serve all sorts of essential functions. They act as signaling molecules, neurotransmitters. They act to facilitate the transport of molecules. They sometimes can act as antioxidants. So some of these peptides are going to sound really familiar. Some of the most important things that people have heard of like endorphins, insulin, GLP1, these are all peptide hormones. Now of course some of these things can be produced synthetically. So we're able to create peptide-based therapies that can mimic the endogenous or body-produced peptides. So again, I would say here the single most important of these would be insulin. Insulin was discovered roughly 100 years ago and it was clear that in a disease called type 1 diabetes that people who lacked insulin because their beta cells were being attacked by their immune system were going to die. And if we couldn't give them some form of insulin and initially that was done by taking insulin from dogs or pigs that they were going to be in trouble. But ultimately of course once insulin could be synthetically produced you could create a therapy to save the life of somebody with type 1 diabetes. More recently of course people will be very familiar with the GLP1s. We're going to talk about that because in the GLP1 world we're not typically giving people the exact same peptide but we'll come back to that. So anyway that's maybe more than you want to hear but we'll start with that as a definition. It's good for people to hear how many different molecules the word peptides can cover. But I think a lot of times when people are asking questions about peptide supplements traditionally it seems like they're not always referring to insulin or even GLPs. And so for the sake of this conversation today and not having 18 hours to go over everything what is your goal with the peptides you want to make sure we talk about today? Well it's interesting we're going to actually talk about these a little differently so we're definitely not going to talk about insulin today. We will talk a little bit about GLP1 but from a sort of regulatory standpoint. In medical terms I would say a peptide broadly refers to an FDA approved therapeutic molecule again like insulin or GLP1 drugs. But I think in the more colloquial sense the word peptide as we're going to talk about it today is more of the biohacking pop science, bro science connotation that refers to various therapeutics that are touted for various benefits often related to quote longevity and beauty and tissue healing recovery performance. But they don't have an FDA approval at all or they're being just used off label for any of these purposes. So when we're going to talk about peptides we're going to be talking about things that are generally administered via injection that have become popular despite a lack of scientific or medical consensus on their efficacy. These are going to be things that are virtually all available through gray market means and again we're going to talk about what that actually means and why that's necessary. By necessary I mean why that's the means by which you would acquire these things in which their sale isn't technically illegal but by marketing them for quote research use only and I'm being very clear in that language they're not approved for human use but everybody understands that they are indeed being used by people. Yeah and given that a lot of these are gray market not FDA approved peptides how do you recommend people start to think about them and start to evaluate the potential of whether they can be helpful or not? I think we want to talk about this across the entire spectrum of efficacy and safety but I don't think we want to even entertain the question do peptides work as a category. The answer is obviously they do. Again we'll point to GLP1 agonists, insulin and even longer proteins that are probably on the verge of still being peptides like HCG that are clearly clinically efficacious. So I think what we want to really do is take an unbiased approach and evaluate whether any given peptide has enough evidence for its safety and its actual efficacy examine the regulatory structure of it and ask the question is there a justification for real world use and again I think this is most helpful when evaluating things through the lens of these unregulated peptides and that's really where we're going to focus today. That's the value I think we can bring in this podcast to this discussion. So again whether you're FDA approved or not I think you should always be asking the same question of anything you put in your body. Let's just take a few steps back and not even think about the lens of a peptide. If you're going to put any drug in your body you should be asking these questions and the answers to these questions should be kind of informing your decision making. So the first question is is there a viable mechanism of action? There's very technical ways to think about this. I'm not interested in vague theories like oh it boosts energy production that's not a mechanism of action. What we want to know is do we have a defined course of mechanistic steps that might logically lead to an intended effect. So this is very important. In fact the list of drugs that are approved by the FDA for which we don't have a mechanism of action is very small. It's estimated to be no more than 3% of total drugs that are approved and this includes over the counter drugs. If there's no mechanism of action you should be very skeptical of a drug or supplement. This is everything that you get a prescription for and everything that is sold legally over the counter less than 3% of these we don't understand the mechanism of action. Now there are some interesting examples. So Tylenol is an exception. Believe it or not we don't actually know how Tylenol works. We don't know how lithium works. We did a newsletter on this somewhat recently talking about lithium for potential cognitive benefits. We don't actually know how it works. There's some speculation but we don't know. Something like mucinex. We don't really know how that works. So there are exceptions out there but they're very rare. Another question you should be asking is what do we know about the downstream effects of this in healthy individuals? That is the intended effect. So this is another way of saying what is the efficacy of this drug in particular in healthy humans or in the patient population that we're interested in addressing this in. Of course another question is what do we know about safety? And that usually means starting in animals but eventually you have to figure out what the safety looks like in humans. And of course that's also a function of dose and usage pattern. How do you put these things together? Well how do you then weigh the potential risks of the potential side effects with the intended benefits of the drug? Take something like an antibiotic. Antibiotics have lots of side effects. Some of them can be really quite devastating but we also know that they have really important intended downstream effects. As such nobody would ever suggest you just take antibiotics willy nilly. That would not make sense to ward off any potential bacteria in the room. Rather we reserve them for when the risk of not taking the antibiotic is high enough. Another question I think we always want to be asking is are there legitimate approved alternatives available? This is actually specific to the peptide question because again once you start to talk about things that are gray market where you have no way of scrutinizing the legitimacy of a compound you have to ask yourself well if I'm going to take this should I be at least considering something that is FDA approved that might have the same risk and benefit profile. Once you answer all of these questions you can put any one of these peptides into basically a group of buckets. You know me I love my frameworks. So this is kind of a framework that we've come up with that I think you could put any peptide into and there's four buckets. So bucket one will be you've gone through this line of inquiry and you really can't make a compelling case for it if you're being honest. You can be dishonest and come up with compelling cases for anything but if you're being honest intellectually honest there would be no use case for this peptide. So these would be things for which you have no viable mechanism of action. You just don't have data or there's some theoretical mechanism or there's existing data that actually refute it. You don't have any data in humans or you might even have negative data in humans. Another thing to look for with these peptides is when you get a lot of shifting goal posts for the alleged benefits. These are peptides where they tout one set of benefits and then they a couple years later come out with a new set of benefits and then a new set of benefits and they're just kind of making up a new story all the time. Then you have your bucket two peptides. Here you have a viable mechanism but the compound has never entered clinical trials or if it did enter human clinical trials it was abandoned. There's no real continued interest from pharma. So we're going to talk about some examples there. Your bucket three peptides have a viable mechanism of action. They might even be currently in human clinical trials. They might even be approved for indications other than those that are intended in the general use population. You do have safety and efficacy data though not necessarily in the population you're interested in or for the indication you're interested in but they don't have an approved version that exists for the current popular use. We're going to talk about examples in all of these. Only the fourth bucket these are basically peptides that are stolen FDA approved drugs or hormones. So they're basically peptides that are being sold that are being touted as exact replicas of approved drugs but they're being sold illegally via research purposes only. So we're going to talk through a handful of examples in a lot of detail to sort of a cover those peptides because these are very popular ones that's why we've chosen them but also to kind of lay out the thinking that we'd like you to do as you embark on this journey yourself. I'll point out that in the show notes we're also going to include kind of a database we've put together of I would say oh I don't even know I've lost track maybe 20 other peptides that we've come up with our own point of view on. Okay. So what are the ones we're going to start on? We're going to kind of go a little deep into the following. 1. S31. 2. Milana 10. 3. CJC 1295. 4. BPC 157. Why did we pick those four? They're incredibly popular. They're probably the ones I get asked about the most from patients, friends, anybody and our goal is to evaluate them through the lens of these questions we just laid out. What are the clinical claims? What's the evidence? What are the risks? What are the practical considerations, etc. So hopefully this gives you sort of a framework to evaluate any other peptide including the ones that we will cover later on. We're then going to talk about these questions, the gray market peptides and talk about how these things are subject to some regulatory oversight, etc. Let's just dive into it. Let's do it. Let's start with the first one, SS31. Let's start with the question is there a viable mechanism of action that we know for it? Thank you for listening to today's sneak peek AMA episode of the drive.
