InterventionPeptides
Peptides are short chains of amino acids, the building blocks that also make up proteins. Your body makes thousands of them, including hormones and signalling molecules. As products they differ widely: some are approved medicines, collagen peptides are an ordinary supplement, and others, such as BPC-157, are sold without having been properly tested in people.
