We’re Pura Peptides — a U.S.–based supplier of research-grade peptides. Our focus is quality and transparency: we list 99% purity and independent testing across our range so labs can source materials with confidence for analytical and in-vitro work.

Our catalogue spans multiple research molecules (including GLP-1–related peptides such as semaglutide and retatrutide) with clear product pages and usage notes. Every item is sold strictly as a research chemical and is designated for in-vitro testing only — not for human consumption.

Ordering is straightforward and lab-friendly: browse the range, place your order, and track support through our contact page. Policies such as returns, terms of service, and a research-use waiver are published in plain English, and we prioritise fast shipping so researchers can keep projects moving.

We’re committed to compliant supply and responsive service. You’ll also find independent customer feedback on Trustpilot, and company listings that confirm our United States base — part of our commitment to being easy to evaluate and easy to work with.
