Prime Research Peptides

74/100

Aggressively-priced US-based vendor that carries the full GLP-1 mainstream — Retatrutide, Tirzepatide, and Semaglutide all in one catalog. Public-facing brand "Prime Research Peptides" appears to be a storefront for Truform Compounds (same parent company, confirmed via about page). Strong on price, weak on public COA surface — testing is claimed but documents aren't published.
