About

PeptideSupply.us supplies research-grade peptides to researchers, educators and laboratories across the United States. We started from one idea: the people buying research compounds deserve to see the proof of what's in the vial.

What we do

Independent testing. Every batch goes to an independent lab before it goes on sale, and the certificate of analysis is published in full, with the lab, batch number and test date. You can read it before you order.

Plain information. Each product page says what the compound is, its specifications and how to store it. We don't make medical claims or give advice on personal use.

Fast, careful shipping. Monday to Friday, orders placed before 2pm PT typically ship the same day from Orange, California.

Research use only

Everything we sell is intended solely for in-vitro laboratory research. Our products are not drugs, foods, supplements or cosmetics, and they are not for human or veterinary use.
