Our story in one sentence
We are a US-based supplier of research-grade peptides and blends, synthesized in cGMP-compliant facilities, with every batch independently verified and published as a lot-specific COA.
No catalog-wide "99%+" claim. No unverifiable marketing numbers. Just a lot number, a lab report, and a guarantee that the two match.
How we got here
Founded
Trypsyn is established around a simple premise: sell research peptides the way a lab would buy them —with evidence, not promises.
Independent testing program
Every batch moves to independent ISO 17025-accredited lab verification, and the first public COA database goes live.
cGMP synthesis partners
Production is consolidated with cGMP-compliant US synthesis and lyophilization partners, enabling full traceability from synthesis to shipment.
Catalog expansion
The catalog grows to cover GH-axis, repair, cognitive and cosmetic research categories plus pre-measured blends.
Today
Every order ships with a batch-specific COA, same-day dispatch on stocked lots, and a 30-day research guarantee.
Four principles, zero exceptions
Evidence over claims
Per-lot purity data beats catalog-wide marketing percentages. We publish what we measure.
Traceability as standard
A lot number on every vial, a COA for every lot, and a lookup that actually works.
Built for researchers
Clear labeling, fast dispatch, volume pricing and a support team that answers technical questions.
Compliance by design
Research-use-only framing, clear disclaimers and packaging that leaves no ambiguity about intended use.
