How Every Batch Gets Verified

Our testing process is non-negotiable. Every product you see in our catalog has gone through this exact process before it ever reaches a researcher.

01

Synthesis & QC

Each peptide is synthesized via solid-phase peptide synthesis (SPPS), purified by preparative HPLC, and lyophilized under nitrogen before any external testing begins.

02

Independent Lab Testing

Samples are shipped to an independent, accredited third-party laboratory with no affiliation to Veltrigen. The lab performs HPLC purity analysis and identity confirmation by mass spectrometry.

03

Published As-Received

The Certificate of Analysis you see below is published exactly as received from the lab — no edits, no cropping, no modifications. What the lab reports is what we show.
