RUO Codes is an independent directory of research-use-only peptide vendors. Each vendor must show current third-party COAs for net content, purity and identity before listing. Coupon checkout-confirmation dates are shown where recorded. We earn a commission when you use code CHAD.
CHAD is our exclusive code at most vendors, and we earn a small commission when you use it. Vendors cannot pay to be listed, and we remove those who stop meeting the standard.
