Precision Signals. Profound Results.

Peptide therapy uses short chains of amino acids that act as precise signaling molecules. They can direct hormone production, cellular repair, metabolism, recovery, and longevity. At Arbour Longevity, every protocol is clinician-designed based on your full labs and health history, and given under licensed clinician supervision with full regulatory disclosure.

Regulatory status varies by compound. Tirzepatide is FDA-approved for type 2 diabetes and obesity. PT-141 (Bremelanotide) is FDA-approved for hypoactive sexual desire disorder in premenopausal women. Other compounds are investigational or have not been reviewed or approved by the FDA for the use being considered. At Arbour Longevity, we disclose the regulatory status of every compound in full at consultation, and you'll complete written informed consent before any protocol begins. Availability of specific compounds may change based on current FDA regulations.

When a licensed clinician prescribes and supervises it after a full evaluation, peptide therapy has an established safety profile for appropriate candidates. At Arbour Longevity, every protocol requires baseline labs, a complete health intake, and ongoing monitoring. Every patient gets full informed consent documentation, including the regulatory status and known risk profile of each compound in their protocol.

Arbour Longevity in Ann Arbor offers clinician-supervised peptide therapy across six categories: growth hormone support, metabolic and weight loss, regenerative and healing, sexual health, longevity, and cognitive performance. All compounds come from regulated compounding pharmacies. We serve Ann Arbor, Ypsilanti, Saline, Dexter, Chelsea, Milan, and Pittsfield Township across Washtenaw County.

Hormone therapy replaces or adds hormones directly, like testosterone, estrogen, and progesterone. Peptide therapy signals your body to produce hormones and other compounds more efficiently, working upstream of the hormone itself. Many patients benefit from both as part of one longevity protocol: hormones restore what's deficient, while peptides can improve the signaling that makes hormone therapy work better.

Results vary by compound, indication, and individual response. Growth hormone secretagogues may improve sleep and recovery within 2–4 weeks, with body composition changes usually by 8–12 weeks. Tirzepatide generally shows measurable metabolic changes within 4 weeks. Regenerative peptides may show a tissue response within 2–6 weeks. We assess full protocol outcomes at your 3-month clinical review with follow-up labs. Individual results vary.
