Every batch verified. Every result documented.
Evercore Labs LLC was founded on a simple standard: researchers deserve to know exactly what's in the vial they're ordering. We supply lyophilized peptide reference materials for laboratory research, and every lot we release is independently third-party tested and documented with a batch-matched Certificate of Analysis before it ever ships.
Purity claims are common. Documentation is not.
We built our process around the second one. Every product we carry is tested by an independent third-party laboratory using HPLC and mass spectrometry, and the resulting Certificate of Analysis is published in our COA Library — searchable by lot number, so you can verify the exact batch you receive before you ever open it.
This isn't a marketing claim layered on top of the product. It's the foundation the business is built on: no compound goes out the door without documented identity and purity behind it.
Well-documented reference materials
Evercore Labs LLC supplies GLP-1, GIP, and amylin-receptor research peptides — Tirzepatide, Retatrutide, Semaglutide, and Cagrilintide — for laboratories and researchers studying metabolic and energy-balance pathways. Our catalog is deliberately focused: a small set of compounds, supplied across a full range of sizes, with consistent, well-documented material behind every vial.
Built for researchers & labs
Our customers are researchers, laboratories, and institutions conducting legitimate in-vitro and laboratory research. All products sold by Evercore Labs LLC are intended strictly for research use and are not intended for human consumption, veterinary use, or any therapeutic or diagnostic purpose.
Credible research starts with a credible source
The research peptide industry has a documentation problem. Too many suppliers make purity claims with nothing to back them up. We think that's backwards. Every Evercore Labs LLC product ships with the paperwork to prove what's inside.
