Research peptides & reference materials
Certificate-grade research materials for qualified labs.
VSA BioScience supplies research peptides and biochemical reference materials to
qualified laboratories and researchers. Every lot is independently third-party tested
for identity, purity, and concentration, then ships with a Certificate of Analysis you
can trace back to the exact vial in your hand — no guesswork, no unverified claims.
Create a free account to view the full catalog, transparent pricing, and every lot's
COA. Access is limited to verified research purchasers, which keeps us aligned with
research-use-only requirements — and keeps the catalog in the right hands.
- ≥98% purity floor
- 100% of lots third-party tested
- Every lot ships with a COA on file
What every lot carries
Identity, purity and net peptide content are measured by an independent laboratory
before a lot is released for sale. Purity is determined by HPLC; identity is confirmed
by mass spectrometry. The certificate names the lab, the lot number and the analysis
date, so a result can be traced to the vial rather than taken on trust.
Why the catalog requires an account
These are research-use-only materials, not consumer products. Access is limited to
verified research purchasers who attest to research use, which is how we keep the
catalog aligned with research-use-only requirements. Pricing, stock and certificates
are all visible once an account is created — nothing about the documentation is
withheld from a qualified purchaser.
Learn how the testing works
Our education library explains the analytical methods behind a certificate: how to
read a COA, what a purity figure by HPLC does and does not tell you, why net peptide
content differs from chromatographic purity, and how storage affects a lyophilised
powder. Written about what researchers measure and how they measure it.
