In this video, I break down one of the fastest-growing trends in health right now, peptides. From BPC-157 and TB-500 to GLP-1 drugs like semaglutide, these compounds are being promoted as shortcuts to fat loss, muscle gain, recovery, and longevity. But what’s the real cost? I explain what peptides actually are, how synthetic versions differ from the ones your body naturally produces, and why the lack of human research should give us pause. We’ll also look at emerging concerns — from contamination and mislabeling to potential long-term effects on metabolism, hormones, and even cancer-related pathways. Right now, millions of people are experimenting with compounds that are often unregulated and not well studied in humans. At the end, I share what I personally do to stay lean, strong, and energized at 48 - without peptides, hormones, or drugs. --- --- --- What I Eat In A Day https://youtu.be/D1kPl9injXw My Bloodwork Review https://youtu.be/qigwrWJEo6Q --- --- --- If you can't get fresh heart & liver in your diet, try our 100% grass-fed desiccated beef organs at Heart & Soil: https://shop.heartandsoil.co/?utm_source=youtube&utm_medium=video&utm_campaign=VIDEOID Looking for a healthy and delicious snack?

Let me know what else you guys would like me to do videos on! I'll be very curious to see how the peptide world evolves in the next few years. I hope they are net positive for humans, and I know there is no such thing as a biological free lunch.

The problem with shutting down gray market peptides is that FDA will never ever approve any of these peptides so that people can actually use them. People want the product in FDA is standing in the way

Paul, I take 1mg of Reta a week, visceral fat is way down, body fat down, blood pressure down VLDL down , strength has increased … I eat a Whole Foods ketogenic diet, sauna every day and exercise. As young as your source is legit, I truly think Reta is as valuable as creatine. That being said I plan on cycling off of this after a few month. Another amazing item I saw was my biological age went down 3 years in a month. You should really try to understand what Reta dues for chronic inflammation and look at rodent studies of tumor shrinkage with Reta…. It’s pretty amazing stuff. I’ve been beating brain cancer for 14 years and this is my latest weapon

It’s insane how underrated book called TestoGenesis Protocol by Angelico still is. Anyone serious about peak testosterone should’ve read this already.

I’ve had great success on the Wolverine stack. I had a grade 5 pec major tendon detachment, and had it repaired. I was surfing in 15 weeks post op. I’m now 7 months post op. I feel 100% and have for 2 months. I’m on my 3rd cycle of the stack. And this will be my last. The recovery for my injury is 1 year. I decided to do everything I could to speed up my recovery. As a side effect, the stack has also healed my gastrointestinal autoimmune disease completely. For the last 13 years I had to limit my diet to carnivore. This was trial an error for my own survival that led me to carnivore. I had great success on carnivore no doubt. But any small deviation, even half a decade into the diet, could send me into a tailspin with gut issues. For the first time in a decade I can eat ice cream and hot sauce, and can also eat after 3pm without it destroying my sleep. That said, I’m still primarily carnivore and have been successful with carbs again. Not that I want or crave carbs, but they’re at least an option again. NO BS! I’m 44 and between 12-15% body fat and surf 4 hour sessions everyday no problem, even after a pec major detachment surgery. As a side note, I’ve had tiny skin cancers on my face for 15-20 years; tiny tiny scabs that never healed. The Wolverine stack at first did seem to make them flare up, but then they went back to the state they’ve been at for nearly 2 decades. It could’ve be the angiogenesis. Idk. I recently went in, after 2 decades ignoring them, and had them frozen off. Another side note: the autoimmune disease I believe I acquired from the DOD forcing me to take MMR three times as a term of employment! That’s when all my problems started. I had some recession in my hairline that could’ve been brought on by the gastro autoimmune disease. The wolverine stack, nearly a decade later seems to be regrowing my hairline to some degree…or it’s that it healed my gut and now I’m not under stress from zero carbs and a decade of meat and high activity levels like surfing regularly.
