Slovak shop that publishes its full certificate archive: 79 reports from Apigenex and Liquilabs, 9 checkable on the lab's own server. Older lots run short of label; 2025-26 Liquilabs lots meet it. Sells retatrutide as "GLP-3". Public-data audit, no first-hand order, 62/100.

VENDOR AUDIT

POWERpepsUSA

New US shop on a WooCommerce storefront, domain registered April 2026, selling 22 research compounds with unusually complete certificates: full panels on 17 of 21 products, mostly from Optiq Health Labs, a real California lab. None of it is in our independent mirrors, two certificates come from an unverifiable lab, pricing runs well above our index on several staples, and payment is Venmo or Zelle only. Retatrutide is sold under its real name and we found no FDA action. Public-data audit, no first-hand order, 64/100.
