What does 'research grade' mean for a peptide?

It is a marketing term with no legal or regulatory definition. It usually implies the product is intended for laboratory research rather than human consumption, the same territory as 'research use only,' but the phrase itself does not guarantee a specific purity, testing standard, or manufacturing practice. A certificate of analysis from an independent laboratory is the only way to check a specific vial, and this site's laboratory profiles describe what each testing lab discloses about how it reports.
