Peptides are short chains of amino acids that act as signaling molecules in the body. In clinical and wellness settings, certain peptides (and peptide-like compounds) are used to support targeted goals such as metabolic health, recovery, body composition, cognitive performance, sexual wellness, and healthy aging—always based on an individual medical evaluation. Many peptide therapies are provided through compounding and may be prescribed for “off-label” wellness purposes; suitability, expected benefits, and risks vary by person and should be reviewed with a licensed clinician.
