Peptide therapyShort chains of amino acids used as signals
Peptides are short chains of amino acids, the same building blocks proteins are made from. In the body they work as signalling molecules, carrying instructions between cells that influence growth, repair, metabolism and immune activity. Peptide therapy uses specific peptides as treatment, generally by injection, because taken by mouth they are broken down by digestion before they can act.
This is an area with a wide gap between what is claimed and what is established, so it is worth being direct about it. Some peptides are well studied and FDA approved as medications. Others are researched but not approved for general clinical use in the United States. Anything prescribed here follows a consultation, a review of your medical history and a discussion of what is known and what is not.
If a provider anywhere describes peptide therapy as a fix for a broad list of unrelated problems without discussing regulatory status or risk, that is a reason for caution.
