COA
Certificate of Analysis — a lab document that reports identity, purity, and sometimes contaminants.
RUO
Research Use Only. This label does not make a compound safe or approved for human use.
Pharmaceutical grade
A medicine-quality manufacturing standard with stronger controls than research supply chains.
Research grade
Material intended for laboratory research, not for personal treatment or self-administration.
Endotoxin
A bacterial contaminant that can cause serious inflammatory reactions if present in injectable material.
Sterility
A measure of whether a product is free from living microorganisms.
