SteriGenix Analytical vs Gold Standard Analytics
SteriGenix Analytical is a Florida peptide testing name whose certificates began appearing on small vendor storefronts in mid-2026. Its homepage now reads "We are not accepting new orders or new client accounts at this time"; intake is paused until a new payment provider is live. Independent reviewers have also flagged a domain registered only months earlier, no published facility address, and public reports missing the mass spectra and integration tables the site promises. Gold Standard Analytics is open for orders, publishes its address and instruments, and puts every certificate, chromatogram included, in a public library.
SteriGenix Analytical (SteriGenix Analytical, LLC), Jacksonville, Florida (per terms); facility address not published. sterigenixanalytical.com. Facts checked September 9, 2026.
