Our Verdict
Seventy-seven COAs posted on their independent certifications page — four labs (TrustPointe, Kovera, BioRegen, Chromate), continuous testing from August 2025 through June 2026. Average purity 99.74%, floor 99.10% (Tesamorelin, TrustPointe). A notable feature: some batches are double-validated — the same lot tested by two separate labs with matching results. Manufacturer IDs (WF03, VI32) are disclosed publicly alongside each COA, which is an unusual level of supply-chain transparency. BPC-157 has been tested six times across multiple batches (99.46–99.99%), Retatrutide nine times (99.33–99.94%). Seven Finnrick-verified tests add independent corroboration. Ownership disclosure is confirmed. No physical address is published. No pricing data is in our database — the overall score likely understates customer experience. Strong testing infrastructure and multi-lab cross-validation put this vendor above most at the same price tier.
