At REI Co-op, we don't just sell outdoor gifts. We use them, test them, trust them. So we know what to give this season. For joy rides, campfire cheers, and peak views.

We know what to give the people you love who love to get out there, because we're out there too. Just stop in and ask a green vest, like me. For the best gifts out there, shop in store or at rei.com.

Your heart can tell you a lot about your health. Apple Watch Series 12 measures your heart rate every five seconds with the most accurate heart rate sensing in a wearable. So your vitals app, now with heart rate variability, can tell you when something is off. And your readiness score can let you know when to rest and when to push. Hear the story in every heartbeat with Apple Watch Series 12

The features described are for wellness purposes only and not for medical use. iPhone 11 or later required. This is an Apple-conducted study of heart rate accuracy August 2026 Visit apple.com/applewatchseries12.

Hey, everybody, this is Hunter Williams. I hope you're doing amazing wherever you might be in the world. I am excited today because I think this is definitely one that is going to be appearing by popular demand. And today's master class is going to be on IGF. I'm actually going to cover two different products because they kind of fall into the same category here. You've probably seen both of you. You're familiar with the peptide research world. One is called IGF-1-LR3, and the other one is called IGF-1-DES, or D-E-S.

I just call it IGF-1-DES. And they're more or less the same product. The half-lives are a little bit different. But practically, when we talk about applications for research purposes, they're very similar, and we would use them in very similar situations. There's actually another product. I'll probably give you some anecdotes today that is actually bioidentical IGF-1. That's called Increlex. I do have a little bit of personal experience with that, but I'll sprinkle that throughout the presentation today. For most people, that's going to be very, very, very hard to get their hands on, and basically impractical because of sourcing and cost. And so for the purposes of peptide research, we're going to talk about IGF-1 LR3 and IGF-1 today, or IGF-1 DES today. I'm going to go into the research behind them, some of the mechanisms that are going on in the body. And for you guys out there, I'm going to give a lot of my own anecdote today, because this is one, it really came, from my understanding, out of a lot of the bodybuilding world, probably 10 to 15 years ago when peptides were starting to make their way into the bodybuilding world for performance purposes.

And it was really meant to be a substitute for NCRLEX, because NCRLEX was really hard for people to get.

Never really lived up to that expectation. And in terms of bodybuilding, it wasn't something that was making people win the Olympia or anything like that. But when we talk about it today in the context of muscle building, muscle growth, supporting all of the process in the body that lead to muscle growth, this can be one that actually I would feel comfortable saying applies to the category of muscle growth peptides, if that's really a thing. I think when we talk about peptides, they're not directly building muscle, but they're help supporting a lot of the processes in the body that do build muscle. Whereas we look at things like hormones and anabolic steroids, you really see like substantial muscle gain coming out of those. Obviously, that's in terms of the anabolic, that's something that I really talk about. And during the hormones, we obviously need a hormone baseline to be able to build muscle, but some of these peptides we can sprinkle in as nice to have. So that's what we're going to cover today. I'm excited for this one. Definitely one that in terms of popular demand is out there, so I'm excited to get this out there. But as always, before I get in the slides, please make sure you're on the email list. That is the best place to stay in touch with me. Should censorship rear its nasty head anytime in the future. Also too, if you want more private access to me, the best place to do that is my private group, the Axion Collective. The link for that is always in the main link down below. And also too, check out my AI Chat app. As of now, that is in the App Store on Apple and the Google Play Store, so you can actually get that on your mobile device and use it there, and it's a little bit better than the web-based version, although the web-based version is great too. Stay tuned. If you are a user of the app, I'm going to be rolling out some new features very soon to where you can upload PDFs and images and things like that. So stay tuned on that. But without further ado, I'm going to share my screen, and today we are going to talk about IGF1.
