Testing: Labs & Certificates of Analysis
Peptide Giants publishes a lab-reports table of 45 certificates, each with the batch, the measured purity with its tolerance and the test date. 44 are Vanguard Laboratory reports published as PDFs on its own site — for example CJC-1295 no DAC 5mg + BPC-157 5mg, batch PG-6012, 98.91% ± 0.18%, tested August 10, 2026 — and one, Tesamorelin 10mg, links to a Janoshik report. The Vanguard reports give identity and chromatographic purity by HPLC-UV/VIS and the measured quantity of each compound.
On October 11, 2026 Prof. Peptide drew three reports at random from Vanguard Laboratory's own public report list for the brand and matched one to the laboratory's record: CJC-1295 no DAC/Ipamorelin 5 mg/5 mg, lot PG-6030, 99.18%. The panel below lists every certificate's own results.
