Testing: Labs & Certificates of Analysis
The certificates resolve on the laboratories’ own domains, and name Southern Aminos as the client. Two laboratories appear: ILS Laboratories and Freedom Diagnostics. Prof. Peptide resolved two of each. On ILS’s own portal, the SA-3R report for lot RT100726AR and the BPC-157 report for lot BP100726R each name Southern Aminos as the client, with matching product, lot and dates. On Freedom Diagnostics’ domain, search code Sout2603130081 is a report for “GLP-3RT 20mg”, lot RT200326E, and Sout2601140157 one for “GLP-4CG 10mg”, lot CG100126A; both read Client “Southern Aminos”. The certificates Prof. Peptide opened ran from September 2025 to September 2026. ILS panels commonly list identity, purity, net peptide content, endotoxin, heavy metals, sterility and fentanyl screening; the Freedom Diagnostics reports list net peptide content, purity and endotoxin, by HPLC with UV detection coupled with mass spectrometry.
All products are sold for laboratory and research use only.
