Regulation
The phrase appears on nearly every research peptide sold online. It is a statement by the seller about intended use — not a regulatory designation, and not a safety assessment.
Clinical Trials
How to search ClinicalTrials.gov for a peptide, what each field on a trial record means, and how to tell an active programme from an abandoned one.
