Peptide therapy FAQ.
What are peptides?
Peptides are short chains of amino acids that act as signaling molecules in your body. They instruct cells to perform specific functions — like repairing tissue, releasing growth hormone, or modulating immune response. They're naturally occurring but can be supplemented therapeutically.
Are peptides FDA-approved?
Some peptides are FDA-approved for specific indications. Many used in optimization medicine are compounded by FDA-regulated 503A pharmacies for personalized dosing. Your KAYU physician will explain the regulatory status of every molecule in your protocol.
How are peptides administered?
Most peptides are administered via subcutaneous injection (a tiny needle, similar to insulin). Some are available as oral capsules or nasal sprays. Your clinician will guide you on proper technique during your first consult.
How quickly do peptides work?
Most patients notice improvements in sleep quality within 1-2 weeks. Recovery and body composition changes typically emerge at 4-8 weeks. Full protocol effects are usually apparent by 90 days with consistent use.
