Retatrutide just posted Phase 3 numbers that are hard to ignore. ~30% average body weight loss. ~70 pounds lost. Even the lowest dose outperformed what used to be considered best-in-class. But the most interesting part of the story isn't the weight loss. It's the thousands of people already using grey-market Retatrutide before there's an approved pharmacy version available. What did the trials actually do? What dose produced the best balance of results and tolerability? And why might the biggest risk have nothing to do with the drug itself?

Everyone knows Deca. Almost nobody knows nandrolone. It's one of the few anabolic steroids with decades of human clinical data, FDA approval, and legitimate medical use. But that doesn't mean it's harmless. We cover the real evidence behind muscle growth, joint pain, fertility, cardiovascular risk, TRT, and the infamous "Deca Dick." The internet has had this compound wrong for years. Watch the full breakdown below. Thanks to Rugiet Health for sponsoring today’s video! And to our non-sponsors Yapper from TJ Bongiorno and Alp Pouch for powering the recording session. 📷

BPC-157 causing cancer? FDA shutting down peptide trials? “No human RCTs have ever been done on peptides?” In this video, Dr. Alex Tatem — board-certified urologist and fellowship-trained men’s health specialist — reacts to viral claims made on Shawn Ryan Show about BPC-157, TB-500, peptides, angiogenesis, cancer risk, and peptide safety. We break down: • Whether BPC-157 actually causes cancer • The truth about angiogenesis and tumor growth • FDA regulation of peptides and compounding • Why the “no randomized controlled trials” claim is completely false • Human clinical trial data on peptides • The real history of BPC-157 clinical studies • Huberman’s correction of viral peptide misinformation • Why peptide fearmongering could push patients toward unsafe gray-market sourcing This is not bro-science or influencer hype. This is a deep dive into the actual published literature, peptide pharmacology, FDA policy, and performance medicine. Topics covered include: BPC-157, TB-500, peptides, angiogenesis, cancer biology, GLP-1 drugs, Ozempic, tirzepatide, semaglutide, TRT, peptide therapy, biohacking, longevity, anti-aging medicine, compounding pharmacies, peptide legality, Andrew D. Huberman, Ph.D. , Shawn Ryan Show, FDA peptide regulation, growth hormone history, and performance medicine. If you’ve ever wondered whether BPC-157 is dangerous, whether peptides are legal, or whether the internet is fearmongering about peptide therapy — this video is for you.

Everyone wants the fountain of youth. The internet thinks it comes in a peptide vial called Epitalon. It supposedly lengthens telomeres, activates telomerase, improves sleep, and maybe even slows aging itself. But when you actually read the research... The story gets a lot more interesting. We dug through the Cold War origins, the Russian longevity studies, the cancer concerns, the sleep data, and what the evidence really says about one of the most hyped peptides in biohacking. If you've ever wondered whether Epitalon is the closest thing we have to an anti-aging therapy—or just another internet myth—this one's for you. Abud Bakri MD

Enclomiphene has become one of the most prescribed men's health drugs in America. It raises testosterone. It preserves fertility. It isn't a controlled substance. So why did it fail FDA approval? In this deep dive, I break down the actual evidence, who it's great for, why it leaves some men feeling incredible and others feeling nothing, and where the marketing gets ahead of the science. This one's dedicated to two people: Dr. Cameron Maximus🤴🏻 🥷🏻 🧙🏻‍♂️ 🤵‍♂️ , who loves enclomiphene... ...and CoffeeBlackMD , who hates it. Now fight in the comments. 🍿 Watch the full video below. 👇

Imagine a compound that claims to improve focus, boost learning, increase BDNF, and even help protect the brain after a stroke. Sounds like science fiction. It's called Semax—a peptide developed in the Soviet Union that's been used clinically in Russia for over 30 years. So... is it actually a real brain booster? In this video I break down: • The actual human and animal data • How Semax works • Whether it can really make you "smarter" • Side effects and safety • The biggest risk most people completely overlook: the bottle it's coming from I also cover the upcoming FDA PCAC meeting that could determine the future of legal access to Semax and several other peptides in the U.S. If you're interested in evidence—not hype—this one's for you. Have you tried Semax? Did it help your focus, or did you feel absolutely nothing? Let me know below. 👇

The testosterone booster industry did about $6 billion last year. Most of it is built on one assumption: "There's a study" = "It actually works." Those are not the same thing. In this video, I ranked the biggest natural testosterone boosters by one metric only: How much they actually move testosterone levels in real human studies. Tongkat Ali. Ashwagandha. Shilajit. Boron. Zinc. Some surprised me. One nearly doubled testosterone levels. Most of the industry probably won't like where it landed. Watch here 👇

BPC-157 and TB-500 are two of the most talked-about peptides in fitness, bodybuilding, and biohacking. Together they’re often called the “Wolverine Stack” — a peptide combination rumored to dramatically accelerate healing of tendons, ligaments, muscles, and injuries. But do BPC-157 and TB-500 actually work in humans, or is the Wolverine Stack just another example of internet bro-science? In this evidence-based deep dive, Dr. Alex Tatem (board-certified urologist and men’s health specialist) breaks down the real science behind BPC-157 and TB-500 — including their biochemical mechanisms, animal research, potential healing effects, safety concerns, and why pharmaceutical companies have never brought these peptides through full FDA clinical trials. We explore the nitric oxide signaling, angiogenesis, VEGF pathways, actin regulation, and tissue repair biology behind these compounds and explain why rodent studies look promising — but why human clinical evidence is still extremely limited. You’ll also learn about: • What BPC-157 (Body Protection Compound-157) actually is • TB-500 vs Thymosin Beta-4 explained • The origin of the Wolverine Stack peptide protocol • Peptides for tendon healing and ligament injuries • BPC-157 for gut healing and musculoskeletal repair • TB-500 and actin-mediated tissue regeneration • Why most peptide research comes from one Croatian research group • The patent law problem preventing pharmaceutical development • Real risks of grey-market peptide contamination • Why WADA bans BPC-157 and TB-500 in competitive athletes • Theoretical cancer risks related to angiogenesis • What the current scientific literature actually shows If you've ever searched: “Does BPC-157 work?” “What is TB-500?” “Peptides for healing injuries” “BPC-157 tendon repair” “Wolverine Stack peptides explained” — this video breaks down the science. The peptides may be promising. But promise and proof are not the same thing. Drop a comment below: Have you ever used BPC-157, TB-500, or other peptides? What was your experience? 👍 Like the video if you want more evidence-based breakdowns of supplements, PEDs, and peptides.
