VENDOR AUDIT
Prime Research Peptides
Aggressively priced US-listed catalog with full GLP-1 lineup (Retatrutide, Tirzepatide, Semaglutide), but the "Prime Research Peptides" brand is a hostname alias for Truform Compounds — same server, same WooCommerce instance, same page-title throughout. Editorial finding documented below. Pricing remains the strongest in our index for retatrutide on a per-mg basis; the credibility-relevant question is whether buyers know who they're actually buying from.
