By what the FDA has actually decided

Around 130 peptide medications are approved. A much louder group is not. This is which is which, and what the difference means for whether anybody can lawfully supply one.

We do not link to sellers of unapproved compounds, and we publish no dosing for them. Intended use is inferred from surrounding content, and in the seven warning letters dated March 31, 2026 the FDA treated the products sold alongside a peptide as evidence of what it was for. A link is surrounding content.
