Quality you can trace.
Standards you can trust.
Peptyne is a US-based supplier of research-grade peptides, built for scientists, laboratories, and research professionals who refuse to compromise on purity, documentation, or consistency.
Built on Research. Backed by Data.
In an industry where quality varies wildly, Peptyne exists to be the reliable standard. Every compound we offer is documented, tested, and shipped with full transparency — because real research demands materials you can verify.
US Sourced & Shipped
Peptyne is a US-based operation. Every order is fulfilled and shipped domestically from within the United States — no overseas drop-shipping, no customs delays, no guesswork about where your materials came from.
Third-Party Tested
Every batch undergoes independent HPLC and mass-spectrometry analysis to confirm ≥98% purity and verify molecular identity. We don't ask you to take our word for it — we provide the data.
COA With Every Order
A Certificate of Analysis accompanies every product, detailing purity, identity, and batch information. Complete documentation isn't an upgrade — it's the baseline.
Secure & Discreet
SSL-encrypted checkout and discreet, unbranded packaging protect your privacy from order to delivery. Your research is your business — we keep it that way.
Fast Domestic Fulfillment
Orders placed before 2 PM EST typically ship the same business day. With free UPS 2nd Day Air on qualifying orders, your materials arrive quickly and reliably.
Transparent & Compliant
We operate with full regulatory transparency. Every product is clearly labeled Research Use Only, and our compliance standards are published openly — no fine print, no ambiguity.
Our Quality Standards
Consistency is the foundation of credible research. Peptyne holds every product to a rigorous, repeatable standard:
- HPLC Analysis — High-Performance Liquid Chromatography confirms ≥98% purity on every batch.
- Mass Spectrometry — Molecular weight and identity are independently verified.
- Lyophilized Form — Products are supplied as stable, freeze-dried powder for maximum shelf life.
- Controlled Storage — Materials are stored and handled under proper temperature conditions to preserve integrity.
- Full Traceability — Lot numbers and Certificates of Analysis make every product traceable and verifiable.
Our Commitment to Compliance
Peptyne products are sold strictly as research chemicals for in-vitro laboratory research use only. They are not drugs, supplements, food products, or cosmetics, and they have not been evaluated by the FDA.
We make no therapeutic, medical, or human-use claims about any product. Our role is to supply high-quality, well-documented research materials to qualified researchers — and to do so with uncompromising transparency and integrity.
Research with confidence.
