COA & lab verification

COA ✓Third-party testedView Peptyx Labs's COA page ↗

Public, third-party, batch-linked COAs for ~15 SKUs. Lab: Freedom Diagnostics Testing (US) — a recognized independent peptide lab (also used by Modern Aminos). Scope: identity by LC-MS, purity by HPLC-UV, net content; batch linkage via accession # + lot ID; a sampled report shows 99.96% purity. Caveats: COAs are image JPGs rather than signed PDFs, and no endotoxin/sterility testing is shown. ⚠️ Brand-new vendor — domain registered ~30 days before integration (2026-05-26). Zero verifiable third-party reputation (no Trustpilot/Reddit/Eroids footprint); the only organic chatter is a few Looksmax threads, one reporting a slow invoice-to-response experience — most visible promotion is influencer/affiliate-driven (TikTok). Transparency gaps: listed address is a UPS Store mail-drop suite (8903 Glades Rd Ste A8 #2357, Boca Raton FL), contact is a Gmail (peptyxlabs@gmail.com), no founding year / business registration / team disclosed. Operations: same-day ship + free worldwide >$350, but an unusually customer-hostile 7-hour damage-claim window + strict no-refund policy, and checkout routed through Tagadapay (high-risk processor). PeptidePrices is an affiliate partner (25% first-order / 15% recurring) — disclosed per FTC; affiliate status does not influence the rating. Compound identity for the vendor codenames 'GLP-2 TZ' and 'GLP-3 RT' is unconfirmed — listed under Tirzepatide and Retatrutide respectively per the standard gray-market dual/triple-agonist naming convention (pending vendor confirmation).

Our verdict on Peptyx Labs

Yes — Peptyx Labs checks the box that matters most: real, public, third-party Certificates of Analysis tied to specific batches. Each report comes from Freedom Diagnostics Testing, an independent US lab, and covers identity by LC-MS and purity by HPLC-UV, with a sampled report showing 99.96% purity. That's the gold standard for verifying a research peptide.

Pair that with a US base, credit-card checkout, same-day shipping, and free worldwide delivery over $350, plus the 25%-off code (PEPTIDEPRICES25), and it's a genuinely strong option. The one piece of context: Peptyx is brand-new, so it hasn't built the long Trustpilot/Reddit track record the established vendors carry, and a few transparency details (mail-drop address, Gmail contact) are worth noting. The COA foundation this early is exactly what you want to see.
