The certificates resolve on the laboratory’s own domain, and name Crownwell Research as the client. Certificates are issued by Freedom Diagnostics and published on a COA library page and on the individual product pages. Each carries a search code, and that code resolves at coas.freedomdiagnosticstesting.com — the laboratory’s own host, not Crownwell’s. Five were opened and read: Crow2602020049 is a report for “Reta-GLP3 10mg”, lot CW-RT10001, averaging 99.09% across two vials; Crow2602110326 covers “Tirz-GLP 2 10mg”, lot CW-TZ10001, at 99.881%; Crow2603230021 covers “BPC-157 10mg”, lot CW-BP10002, averaging 99.32%; CROW2608111074 covers “Adamax 10mg”, lot CW-AD10001, at 99.88%; and Crow2608240592 is a separate endotoxin report for “GLP3-R 30mg”, lot CW-RT30003, recording a pass on both replicates at an assay sensitivity of 0.05 EU/mL. All five read Client “Crownwell Research”, and each laboratory-hosted file is byte-identical to the copy Crownwell serves. The reports read span February to August 2026. Chemical analysis is by HPLC with UV detection coupled with mass spectrometry; the endotoxin report uses a Limulus Amebocyte Lysate assay under USP <85>. The figures above are the results recorded for those lots, not a published minimum specification.
