High-Purity
Laboratory-Grade
Peptides
BioIntegrity supplies research-grade peptide compounds to laboratories and research professionals for controlled, non-clinical investigation of biological signaling pathways.
Published results. Permanent records.
Most suppliers will send you a certificate if you ask. We publish the results instead — purity, identity, and endotoxin, with the label claim beside the measured content — as permanent records you can read before you order and cite afterwards. Records stay published after a lot sells out.
Verification
The certificate archive is the product
Each record lists the assay, the method used, and the measured result. Records stay online permanently, so material cited in published work remains verifiable years later. Below are certificates for the compounds most requested this year.

How to Read a Peptide Certificate of Analysis
What each assay measures, which figures matter, and how to spot a certificate that is not what it appears to be.
HPLC Purity vs. Mass Spectrometry Identity: Why You Need Both
The two analytical methods answer different questions, and a certificate with only one leaves a gap.
