Built for the bench, documented for the record.
Cornerstone Peptides supplies research-grade peptides and custom synthesis with per-lot analytical documentation and independent verification on request.
The buyers we serve — academic groups, contract research organizations, biotech and pharma R&D, and analytical labs that need characterized reference material — all want the same two things: peptides in research-appropriate quantities, and the documentation to stand behind every milligram.
We supply lyophilized powder and bulk active for the bench, and we synthesize custom sequences to order — with modifications, purification and an analytical package specified to your protocol. What we do not do is as important: no finished or injectable dose forms, no products intended for human use, and no patented molecules.
The Standard
Every lot: one Certificate of Analysis, with HPLC and mass-spec identity — plus independent verification on request.
We do not compete on price. We compete on the paper trail.
