Vendor Vetting & Testing Standards
Every vendor listed on RUOcodes.com — including Good Labs — must provide current Certificates of Analysis (COAs) from independent third-party laboratories before being listed. At minimum, each COA must confirm net content (actual quantity of the compound), net purity (verified purity percentage), and compound identity (confirmation that the substance is what it claims to be). Vendors that cannot document their testing standards are not listed, regardless of how many coupon codes they offer.
Higher-standing vendors additionally provide endotoxin testing, sterility testing, heavy metal screening, and conformity testing to reference standards. These tiers are visible on the Good Labs vendor page so you can evaluate the full testing profile before purchasing.
