GHK-Cu is a rare grey-market peptide with genuinely strong topical evidence behind it — decades of published dermatology research and real randomized trials on skin and wound healing. The injectable, systemic anti-aging version sold today is a different claim entirely, resting on animal data and gene-expression studies that were never designed to prove what the injection ads imply.

The Huberman Lab Peptides Episode, Reviewed: What Dr. Bakri Said and What Survives Scrutiny In June 2026, Andrew Huberman spent nearly three hours with physician Abud Bakri walking through BPC-157, GHK-Cu, epithalon, pinealon, thymosin alpha-1, GLP-1s, and retatrutide. The episode is a genuinely useful map of what people are injecting and why. It is also a case study in how conversational time can flatten a very steep evidence gradient. A peptide-by-peptide fact-check of the claims, the mechanisms, and the regulatory maze in between.
