Summary
Biohackers and longevity clinics claim peptides are a side-effect-free sniper rifle for fat loss and injury recovery, but the reality is often buried in failed clinical trials and regulatory bans. Many popular compounds like BPC-157 have never undergone a single randomized controlled trial in humans, despite their reputation for Wolverine-like healing. This episode dismantles the hype surrounding the gray market, exposing the significant risks of immunogenicity and heavy metal contamination. Learn why modern load management and evidence-based medicine beat a research chemical bought with Bitcoin every time.

Key Points
- The FDA Category 2 Crackdown: Federal regulators restricted many peptides because of the risk of immunogenicity where the body creates antibodies that attack its own proteins.
- BPC-157 Has Zero Human Data: Despite being marketed for tendon repair, there is not a single published human randomized controlled trial for this molecule.
- The MK-677 Prediabetes Tax: While it increases lean mass, human trials show zero improvement in strength or power while frequently causing insulin resistance.
- Retatrutide as the Weight Loss Godzilla: This triple agonist is achieving nearly 29 percent weight loss in trials by increasing energy expenditure through thermogenesis.
- Sourcing and Safety Realities: A study of 44 research chemicals found that only 18 actually contained the labeled compound, with many containing heavy metals.
- The 40-Amino-Acid Rule: The legal distinction between a peptide and a protein is based on size, which dictates how the FDA regulates these substances and how your body absorbs them.

Clinical Pearls
- Use load management and progressive resistance training as the primary intervention for tendon and muscle injuries rather than unproven peptides.
- If choosing to use metabolic modulators, monitor fasting blood glucose and insulin sensitivity to avoid drug-induced prediabetes or metabolic dysfunction.
- Avoid the research chemical gray market entirely due to the high prevalence of under-dosing, contamination, and incorrect active ingredients found in third-party testing.

| 0:00.0 | In 2006, a biotech firm thought that they had discovered the holy grail of human performance. |
| 0:08.0 | They had a compound that could elevate growth hormone for days with a single injection. |
| 0:13.0 | But they abruptly shut the entire program down. |
| 0:16.0 | Why? Because a healthy subject died of a heart attack. |
| 0:27.9 | That drug was C.J.C. 1295. |
| 0:30.0 | And today, that exact same compound is being sold by the gallon on the internet to biohackers |
| 0:33.9 | and 20-year-old lifters trying to get jacked. |
| 0:36.4 | Welcome back to the Barboh Medicine podcast. I'm Dr. Jordan Feigenbaum, and today we're going to do a forensic audit of the entire peptide market. They're often billed to be safer and more effective than anabolic steroids, and these compounds have been moving from the underground forums into mainstream longevity clinics, and we need to look past the hype. Now, our goal today isn't to dismiss peptides out of hand, but to apply the same standard we use for everything else. What does the human data actually show? Are the results meaningful, or are we just looking at mechanisms in petri dishes? And to help us separate the signal from the noise, I'm joined by the second most handsome doctor in North America, Dr. Austin Baraki. Now, Austin, before we get into these specific molecules, |
| 1:11.3 | we have to address why this topic is blowing up right now. In late 2023, the FDA essentially |
| 1:16.5 | declared war on the peptide supply chain, moving dozens of popular compounds to a restricted list. |
| 1:21.7 | Now, there's a massive amount of confusion here regarding what is actually legal, what is |
| 1:24.9 | banned, and what is just plain dangerous. To set the stage, we need to distinguish between three different bodies, the DEA, the FDA, and WADA. Austin, can you break down the difference for our listeners between a drug being scheduled for criminal activity versus a drug being restricted by the FDA for safety? Yeah, I think a lot of the drugs that people think of as being, quote, unquote unquote illegal are in that list of what are called |
| 1:44.5 | scheduled controlled substances. The DEA is kind of responsible for that. There is a kind of a tiered |
| 1:49.7 | classification of one through five. And these relate to varying degrees of abuse potential |
| 1:56.2 | addiction versus potential medical use and the degree of like monitoring that might be needed if somebody |
| 2:01.2 | is to use some of these depending on what level they're scheduled at. |
| 2:03.6 | These are things on the extreme like heroin, for example. |
| 2:07.6 | Even cocaine technically has some legitimate medical uses still today. |
| 2:10.6 | Testosterone is unfortunately on this list. |
| 2:12.6 | I don't really think it should be, but it is. |
| 2:14.6 | Xanax definitely should be on this list, opioids, things like that. These are things that, A, require a special DEA license, like one that I have, to prescribe, you know, within certain restrictions and limitations and oversight regulation. But possession of these without a prescription is usually considered a crime. And now, if you contrast that with a lot of these peptides, the DEA is not really paying attention to these at the moment. They're not scheduled. They're not on this list. There's not like a way that somebody with a DEA license can specifically prescribe you BPC or any one of these peptides. They're just not on that list at all. So what you're saying is that the DEA isn't kicking down your door for having BPC 157, but the FDA |
| 2:52.1 | has effectively nuked the supply chain. In recent years, you could get these from compounding |
