Research-backed answers on peptide therapy — what the science says, what the law says, and what’s actually available.
Peptides are short chains of amino acids — the same building blocks that proteins are made of, just smaller. Your body produces thousands naturally as signaling molecules: telling cells when to divide, when to heal, when to release a hormone, when to sleep. A primer on how therapeutic peptides use that language.
