Two audits, side by side. Composite, subscores, shipping, payment, coupons. Prime Research Peptides takes the higher composite this cycle.
Composite score
Prime Research Peptides
68/100Aggressively 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.

55/100Operator received an FDA warning letter on December 10, 2024 as "Summit Research Peptides," then rebranded to Summit Biotech without disclosing the prior identity on the new site. Login-walled catalog, code-name SKUs for the FDA-cited compounds, and the cheapest per-mg pricing in our seven-vendor index on Tirzepatide, Retatrutide, and Semaglutide. ~90% of COAs are real Janoshik public-database links.
