The word “peptide” does not establish whether a product is authorized, appropriate, sterile, correctly labelled, or supported for a proposed use.
Match the full identity
Ask for the ingredient, finished product name, manufacturer, dosage form, route, concentration, DIN when applicable, and intended indication. Verify these details independently.
A certificate of analysis can describe a tested sample. It does not by itself establish sterility, batch identity, clinical effectiveness, or Canadian authorization. See the detailed COA evidence guide at PeptideInfo.ca.
