What the FTC Says About Peptide Marketing (And Why It Matters)

Peptide supplement and research chemical sellers operate under strict FTC and FDA rules. Understanding these rules helps you spot compliant sellers — and avoid the ones that aren't.

Educational purposes only. The information on this page is for educational and research purposes only. It does not constitute medical advice, diagnosis, or treatment. Research peptides are not FDA-approved for human therapeutic use unless explicitly stated. Always consult a licensed healthcare provider before using any compound.

The FTC's Role

The Federal Trade Commission (FTC) regulates advertising and marketing claims in the US. For peptide sellers, this means all marketing claims must be truthful, not misleading, and substantiated by competent and reliable scientific evidence. Claims like 'heals injuries' or 'guaranteed to burn fat' without clinical trial evidence would violate FTC regulations.

Research-Only Claims

Legitimate peptide research chemical sellers restrict their marketing to 'for research purposes only' language and avoid specific therapeutic claims. This is not just a disclaimer — it's a legal necessity. When a seller makes specific health claims while selling a non-FDA-approved compound, they are potentially selling an unapproved drug, which carries significant legal liability.

Affiliate Disclosure Requirements

The FTC's Endorsement Guides (16 CFR Part 255) require that any material connection between a content creator and the products they recommend be clearly disclosed. This includes affiliate relationships. Content sites like this one are required by law to disclose affiliate relationships in a clear and conspicuous manner. PeptidesMasters.com complies with this requirement — all affiliate links are clearly labeled.
