All Things Peptides — Dr. Andrew Huberman
"The gray market is the quote unquote for research purposes only stuff that you can buy online. It's perfectly legal to sell for research purposes only, not for animal or human use. And I joked on X a while ago like, "Wow, all these home labs, everyone's buying this. Of course, people are injecting them.""
Dr Andrew Huberman says peptides sold online as “for research purposes only” are widely being used for self-injection, despite labels stating they are not for human use. He raises contamination and mislabelling risks, and claims many people are already taking Lilly’s retatrutide (which he says is easy to synthesise) before formal release.
