The Science
What Are Peptides?
Peptides are short chains of amino acids — the building blocks of proteins — that act as signaling molecules in the body. They instruct cells to perform specific functions: repair tissue, regulate hormones, support immune response, and more.
Research in peptide science is rapidly expanding. Our physicians stay current with the literature and work with you to explore whether peptide therapy aligns with your wellness goals — always within established guidelines and evidence.
Areas of Interest
Potential Wellness Applications
Research is ongoing. These are areas under active scientific study — not treatment claims.
Recovery & Repair
Some peptides are being studied for their potential role in supporting tissue healing, reducing inflammation, and accelerating recovery after injury or exercise.
Growth Hormone Support
Certain peptides act as growth hormone secretagogues — signaling the pituitary gland to produce more natural growth hormone. This area has yielded FDA-approved therapies for growth hormone deficiency.
Metabolic Health
GLP-1 receptor agonists — a class of peptide-based medications — are now FDA-approved and widely used for metabolic support and weight management.
Immune Modulation
Research is exploring how certain peptides may support immune system regulation, with some showing promise in early studies for immune balance and resilience.
Skin & Collagen
Topical and systemic peptides are being studied for their potential to support collagen synthesis, skin elasticity, and overall skin quality as part of an aesthetic wellness routine.
Sexual Wellness
Bremelanotide (PT-141) is an FDA-approved peptide therapy indicated for hypoactive sexual desire disorder in premenopausal women, with ongoing research in broader sexual wellness.
Regulatory Landscape
FDA-Approved Peptide Therapies
The FDA maintains a limited list of fully approved peptide-based medications. These are the therapies we discuss and, where appropriate, prescribe:
Sermorelin
Growth hormone-releasing hormone (GHRH) analog. FDA-approved for growth hormone deficiency.
Tesamorelin (Egrifta)
GHRH analog. FDA-approved for lipodystrophy in HIV patients; studied in broader metabolic contexts.
Bremelanotide (Vyleesi / PT-141)
Melanocortin receptor agonist. FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women.
Semaglutide (Ozempic / Wegovy)
GLP-1 receptor agonist. FDA-approved for type 2 diabetes management and chronic weight management.
Tirzepatide (Mounjaro / Zepbound)
Dual GIP/GLP-1 receptor agonist. FDA-approved for type 2 diabetes and chronic weight management.
This list reflects FDA-approved indications only. The regulatory landscape for peptide therapy evolves frequently. Our physicians will always discuss current approvals, evidence, and appropriate use during your consultation.
