A guided 5-question wizard that maps you to the FDA-approved peptide options most likely to match your situation. Restricted to FDA-approved peptides — every answer ends with “consult your prescriber.” This is not medical advice and does not replace a clinician.

The real difference comes down to source, amino-acid profile, molecular
