Audit Notes & Receipts

  • First-hand vet (2026-08-11).
  • Peptide Plugs (Austin Research Products LLC, Liberty Hill TX) publishes per-batch COAs from a NAMED independent lab, Freedom Diagnostics (Franklin, TN).
  • We traced a claimed accession from the /coas/ catalog into Freedom Diagnostics’ own public database and opened the lab-hosted COA (accession 2606120657): Client PeptidePlugs.com, VIP 10mg, Lot 138-01-SM, received 06/12/2026 / reported 06/15/2026, HPLC-UV purity 99.75% + LC-MS identity confirmed + net content 9.37mg + fentanyl screen negative.
  • Freedom is a real independent shared lab (multi-vendor, 3,000+ Pept-prefixed COAs).
  • Honest caveats keep this at published-unaudited: of ~117 COA entries only ~72 are Freedom-verifiable (10 ILS with no public portal, 35 blank/no-accession), the COAs omit endotoxin/sterility, the brand is ~7.5 months old, and no independent aggregator (Finnrick/Peptigrity) has re-tested the product. Graded B (69).
  • This is the vendor Ryan’s "Prime 191" (rHGH 191aa) came from.

Green bullets = directly verified data points. Amber bullets = caveats or open questions. Gray = disclosures.

Buyer Caution

Newer brand (~Dec 2025 rebrand of atxpeptides.com) with no track record; of ~117 listed COAs only ~72 are Freedom-verifiable (10 are ILS with no public portal, 35 are blank/no-accession); COAs omit endotoxin/sterility; a historical Venmo/Zelle/Cash App/PayPal-F&F payment option is reportedly retired, confirm card-only before buying.
