DON’T Inject What You Can’t Verify: Compounded Peptide Safety Explained

Over 500 published papers stand behind one of the internet's most popular peptides, but fewer than 30 of the humans studied are in them. Dr. Gabrielle Lyon separates the molecule from the marketplace so you can tell real evidence from good marketing.

In this solo episode, Dr. Gabrielle Lyon discusses:

• Why BPC-157's "mountain of evidence" collapses to a 99.7% animal-to-human ratio - 544 papers, but fewer than 30 humans across three uncontrolled pilot trials
• How to place any peptide on the spectrum from FDA-approved (GLP-1s like semaglutide) to investigational to compounded, and why "GLP-1s work, so peptides work" is a trap
• What the FDA quietly did in April 2026, and why removing a dozen peptides from its safety-concern list was driven by policy pressure, not new safety data
• The 4 questions to run on any peptide before you inject level of evidence, what the study measured, where it's sourced from, and whether it's banned in tested sport
• Why the "boring work", resistance training, protein-anchored nutrition, and real recovery beat almost anything in a vial

If something is going into your body through a needle, the standard has to be higher than three words on a label that say "research use only." This episode gives you the framework to protect yourself before spending a dollar or taking a shot.
