VENDOR AUDIT

Ion Peptide

US research-peptide vendor with the cleanest COA paper trail in our public-data cohort - 120 Kovera Labs reports across two months at a median 99.93% purity, zero failures, zero identity-mismatch. Coded ION-X SKU naming on a subset of products is worth knowing about.

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.
