About us

Precision. Purity. Performance.

Legion Peptides supplies high-purity research peptides to qualified researchers and research institutions. Every lot is assayed by an independent laboratory and ships with its certificate of analysis, from our facility in New York.

Who we sell to

We are a research supply company — not a pharmacy, a clinic or a supplement brand. We sell only to:

  • Qualified individual researchers working in a laboratory setting
  • Universities, hospitals, contract research organisations and other research institutions

We do not sell to consumers for personal use, and we do not sell for use in or on people or animals. An order that indicates personal, human or animal use may be cancelled and refunded, and we may decline further orders from that account.

What research grade means here

  • Third-party assayed for identity and purity before release
  • Certificate of analysis published with the batch, not sent on request
  • Lyophilised powder in sealed vials, kept in cold storage until dispatch
  • Ships within one business day of clearing our checks

What we do not do

We do not provide dosing guidance, protocols for human or animal administration, medical advice, or any information about using these compounds outside a laboratory. Requests of that kind will not be answered.
