You need an account before you can see prices, products or certificates. A signed-out visitor first meets a researcher-verification screen (21 or over, laboratory research use), and then a sign-in page. Getting in means registering with a name, email and phone number and setting a password from an emailed link. The certificate links on this page go straight to PDFs and to the laboratories’ own verification pages, so they can be checked without an account.

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. We 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 we 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.
