Frequently Asked Questions

How do I find a legitimate peptide source?

Look for sources that provide third-party lab testing (COA), have clear GMP certification, offer transparent ingredient disclosure, and have verifiable reviews. Every source on this page has been verified by The Peptide Alliance team.

What makes a peptide source "verified"?

The Peptide Alliance Verified badge is awarded to businesses reviewed by our team for legitimate operation, proof of certifications (GMP, ISO, etc.), and completion of our verification process.

Are compounding pharmacies better than research peptide suppliers?

It depends on the intended use. Compounding pharmacies operate under pharmacy regulations and require a prescription — appropriate for clinical use. Research peptide suppliers offer peptides for research purposes. Both can be high quality — the key is third-party testing and transparency.

What is a Trust Score?

The Trust Score is a proprietary 0–100 rating calculated from certifications, lab results, ownership verification, reviews, profile completeness, subscription tier, product listings, and account age.
