Removal of a substance from a regulatory list does not mean it has been approved. A "research use only" label does not make a product safe or legal for human use.

Counts are PubMed records that mention the peptide in the title or abstract. Categories overlap, and a mention is not the same as testing the peptide as a treatment. Each number opens the exact PubMed search. Effects seen in laboratory or animal studies may not occur in humans. A registered clinical trial does not show that a substance is effective or safe.
