Five tests on every certificate
Test What it checks Method on the certificate Identity That the material is the right molecule Mass spectrometry (LC-MS): observed mass against theoretical mass Purity How much of the peptide material is the target compound Reverse-phase HPLC, reported as area % Net content How much target compound is in the vial, against the label Quantitative HPLC against a reference standard Sterility screen Whether microbial DNA is present Rapid PCR research screen (not a USP <71> sterility test) Fentanyl screen Whether fentanyl or listed analogs are present above the detection limit Targeted LC-MS/MS screen -
The record is sealed at the lab
Each certificate carries a report ID and a QR code. The lab keeps a sealed record of the results, so you can check a certificate on the lab’s own site instead of trusting a PDF.

You match it to your vial
Certificates are published by product and batch. Match the batch number on your vial’s label to its certificate. A product without a published certificate shows “Certificate coming soon” in the store.
A certificate describes the sample that was tested. The certificate itself states that results relate only to the item tested, so always match the batch number on your vial to the batch on the certificate.
