Unlike many peptides, tesamorelin is actually approved by the FDA, though only for helping HIV patients reduce abdominal fat. My Instagram algorithm is flooded with their advertisements showing gleaming factories with thousands of peptide vials rolling off assembly lines. One ad, from a company called “Peptides fatory sale [sic],” promised, “When you find a reliable supplier, you wilt get a refrigerator full of peptides.” It included a link to chat on WhatsApp. The clip is captioned, “how life feels when we have random chinese research chemicals in our bloodstreams.” Typically, people making videos about peptides have affiliate links for peptide vendors in their bios. In May, on a podcast hosted by biohacker Gary Brecka, RFK Jr. promised to “end the war at FDA” on peptides.
