What is the difference between a compounding pharmacy and a research peptide seller?

They are not the same legal picture, and this site's legal-status fields are national approval or research-use lines, not a pharmacy directory. A compounding pharmacy, where the pathway exists, prepares a product for a named patient under a prescription. Sermorelin's US field says prior approval discontinued, available via compounding pharmacies, the remnant of Geref. Tesamorelin, semaglutide, and tirzepatide have FDA approved finished products (Egrifta, Ozempic, Wegovy, Rybelsus, Mounjaro, Zepbound) that are not research chemicals. A research seller labels a vial research use only and not for human use. Compounding is not that research-chemical pathway, and it is not the approved branded pen either. This dataset does not name pharmacies, does not track state-by-state compounding rules, and does not tell you where to buy. Check the compound's /legal page for the national field this site actually stores.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

Part of research peptides, the category. What research peptides are, legally and practically, before getting into specific compounds.
