About Purpeptide
Built by chemists, for the researchers who need certainty.
Purpeptide was founded on a simple principle: research only progresses when the inputs are trustworthy. We synthesize, verify, and ship peptides with the same rigor the laboratory on the other end will apply.
Our promise
Transparency at the lot level
Every vial ships with a batch-specific Certificate of Analysis. Lot numbers tie back to raw HPLC and MS chromatograms, available on request.
Sterile by design
Lyophilization happens under inert argon, and final vials are sealed in ISO-7 cleanroom conditions to preserve stability and purity.
Cold-chain logistics
Orders ship within 48 hours in insulated, temperature-controlled packaging — domestically and internationally.
No grey-area marketing
We never make therapeutic claims. Our products are research tools, sold to qualified researchers, full stop.
