Testing: Labs & Certificates of Analysis
Paramount's certificates come from Janoshik and Accumark Labs. Its certificate lookup finds a certificate by the lot number printed on the product label or by product name, and each result names the compound, the analysis date, the lot and the laboratory.
On October 14 and 15, 2026 Prof. Peptide found four DSIP certificates from the lookup in the laboratories' own records, each naming Paramount as the client: Janoshik task #121848 (lot DSIP10-02112026-J, purity 99.20%) and three Accumark Labs reports. The latest of those, JXXG-WRTB (lot DSP10N102725, completed August 21, 2026), gives purity of 99.23%, identity confirmed, and passes on endotoxin and a rapid sterility screen. The panel below lists every certificate's own results.
