Find Verified Peptide Coupon Codes
RUO Codes is an independent, community-powered aggregator of verified coupon codes and discount codes for research-use-only (RUO) peptide vendors. Every code in our database carries a real success rate — calculated from community-submitted reports — so you know before you try it whether a code is likely to work at checkout.
About RUO Codes
We track the most widely researched peptides and compounds: BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide, PT-141 (Bremelanotide), Selank, Semax, Epithalon, GHK-Cu, AOD-9604, IGF-1 LR3, CJC-1295, Ipamorelin, SS-31, MOTS-c, Glutathione, NAD+, and more — from every major RUO vendor.
Codes are used by our community of researchers and biohackers, then validated over time through community voting. Our upvote/downvote system surfaces codes that actually work at checkout and flags ones that have expired — keeping the database accurate without relying on any single source or paid partnership. RUO Codes is free, has no paywalls, and does not charge vendors for placement.
Vendor Vetting Standards
Every vendor listed on RUO Codes must meet a minimum third-party testing standard before we add them. We require current Certificates of Analysis (COAs) from independent labs confirming net content, net purity, and compound identity. Vendors that can't document what's in their product don't get listed — a coupon code is worthless if you can't trust what you're buying.
Beyond basic COA requirements, we give higher standing to vendors who provide endotoxin testing, sterility testing, heavy metal screening, and conformity testing. These tiers are visible on each vendor's detail page so you can see exactly how well-tested each supplier's products are.
