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's proof
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.

What the July 2026 PCAC Votes Did and Did Not Change
An advisory committee recommended six peptides for the 503A Bulks List. Four distinct regulatory states are being collapsed into one headline.
How to Read a Peptide Certificate of Analysis
Line by line, using a real published lot: what purity, identity, quantity and endotoxin results mean, and the certificate errors worth catching.
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.
