Research-Use-Only (RUO)
Also known as: RUO · for research use only
A regulatory designation indicating a compound is sold for laboratory research purposes and has not been evaluated for human use.
Research-Use-Only is the legal framework under which most non-pharmaceutical peptide vendors operate. The compound has not been evaluated by the FDA for safety, efficacy, or human consumption. Marketing the compound with therapeutic claims, dosing guidance for humans, or before/after testimonials implying human use collapses the RUO shield and exposes the vendor to regulatory action.
RUO framing is a requirement for vendor legitimacy, not an indicator of inferiority. Many pharmaceutical peptides are sold in both pharma-grade (prescription) and research-grade (RUO) forms with identical active molecules and different regulatory wrappers.
