Peptide questions, answered
What are peptides?
Peptides are chains of amino acids. Some act as signals in the body; others are studied or used in medicines and topical products. The effects and evidence depend on the specific compound, formulation, and use.
Are all peptides FDA-approved?
No. This library includes approved medicines, compounds in clinical trials, unapproved compounds, and cosmetic ingredients. FDA approval applies to a specific product and indication, not to peptides as a group. Compounded medicines are not FDA-approved.
How should I use this peptide library?
Browse by body system or search for a compound. Each guide summarizes its mechanism, research focus, regulatory context, and source references. The catalog is educational and does not establish that a treatment is safe, effective, or offered by Peppy.
