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.

How the dates on this page work. Manufacturer self-pay prices were re-read on 15 October 2026: NovoCare’s Wegovy page and Lilly’s Zepbound savings page. Foundayo prices are carried from LillyDirect pages archived 25 September 2026, because lilly.com blocked automated reads. Figures captured from telehealth provider websites carry the date we read that provider’s page, which may be earlier; where it is, the row or a dated notice says so. We do not restamp a figure we have not re-read.
