This article is educational and does not replace medical advice. Prescription medication requires review by a licensed clinician and, when appropriate, a valid prescription. Compounded medications are not FDA-approved, and the FDA does not verify their safety, effectiveness or quality before marketing. Treatment eligibility is an individual clinical decision.

Peptide therapy overview

An evidence-first overview of peptide therapy: what it is, which peptides are approved, and how to tell legitimate clinical care from research-chemical marketing.

Quick answer

Peptide therapy uses short amino-acid chains for effects ranging from tissue repair to growth-hormone release. Only a few peptides are FDA-approved finished drugs; most marketed for wellness are unapproved. Legitimacy depends on a licensed clinician, a licensed pharmacy, and honest evidence claims.
