Why we exist

Research peptide supply has a reputation problem: unverified purity claims, missing documentation and inconsistent cold-chain handling. The Peptide Company was founded to make the boring things reliable — batch testing, paperwork, storage and dispatch.

How every batch is handled

Each production lot is sampled and sent to an independent UK analytical laboratory for HPLC purity analysis and mass spectrometry identity confirmation. Lots that do not meet our minimum 99% purity specification are rejected outright — never discounted or relabelled.

Handling and dispatch

Vials are stored at 2–8°C in the dark, picked in a controlled area and dispatched in insulated packaging on a tracked service. Orders placed before 2pm on a working day leave the same day.

Research use only

All products are sold strictly for in-vitro laboratory research. Nothing we supply is a drug, food, cosmetic or medical device, and nothing is for human or veterinary use.
