Eleven physician-reviewed guides to the peptide and NAD+ therapies we offer, plus the library index. Each one covers what the treatment is, how it works, what the published research shows, how it's given, and what to expect. Every source is listed, and the U.S. regulatory status is printed on the cover. September 2026 edition.
Start with the index if you're not sure where to begin. And bring your questions to your consultation — that's what these are for.

These guides are patient education prepared by Regen Therapy MD. They are not medical advice, not prescriptions, and not a promise of any clinical outcome. Several of the peptides described are not approved by the U.S. Food and Drug Administration, and some approved medicines are described for uses outside their approved labeling; each guide states the status of its treatment plainly. Individual results vary. GLP-1 medications such as semaglutide and tirzepatide are injection-only. All treatment decisions are made solely by your licensed treating physician.
