PT-141
A melanocortin receptor agonist prescribed at SSK Longevity in Newport Beach, California, for sexual health, libido, and arousal protocols in adults.
A Melanocortin-Pathway Approach to Sexual Health
PT-141 (bremelanotide) is a melanocortin receptor agonist that acts centrally on the nervous system rather than peripherally on the vascular system. It is the active ingredient in the FDA-approved branded medication Vyleesi for hypoactive sexual desire disorder in premenopausal women. At SSK Longevity, PT-141 may be prescribed off-label or in compounded form under physician supervision for adults seeking support for libido, arousal, and sexual response.
Because PT-141 acts through melanocortin receptors in the central nervous system, its mechanism is fundamentally different from PDE5 inhibitors and other vascular-mediated approaches to sexual health. At SSK Longevity in Newport Beach, PT-141 is prescribed by Dr. Sean Kelishadi, MD FACS and compounded under Sherry Kelishadi, Pharm.D.'s direct pharmacy oversight for Newport Beach, Costa Mesa, Irvine, and broader Orange County patients.
Why Melanocortin Activation Is Different
PT-141 acts on melanocortin receptors (primarily MC4R) in the central nervous system, modulating pathways involved in sexual desire and arousal. This central nervous system mechanism is distinct from PDE5 inhibitors that work through peripheral vascular effects.
Central Nervous System Action
PT-141 crosses the blood-brain barrier and activates melanocortin receptors in regions of the brain involved in sexual desire and arousal — fundamentally different from peripheral vascular medications.
MC4R Receptor Activation
Activation of the MC4 receptor in particular has been associated with sexual response in research, the same mechanism behind PT-141's FDA-approved branded form (Vyleesi).
Independent of Vascular Effects
Because PT-141 works through central pathways rather than peripheral vasodilation, it functions independently of (and may complement) vascular-mediated approaches.
PT-141, Compounded for Central Nervous System Action
Every PT-141 protocol at SSK Longevity Newport Beach is compounded under Sherry Kelishadi, Pharm.D.'s direct review. Dose pacing, drug interaction screening, and complementary protocol layering are evaluated individually for each patient before any PT-141 is dispensed.
Newport Beach, Costa Mesa, Irvine, and Orange County patients receive a PT-141 protocol calibrated to their physiology, sexual health goals, and broader hormonal context.

What patients actually say.
"PT-141's mechanism is genuinely different from anything else I'd tried. SSK was thorough about my hormonal context first."
"Dr. Kelishadi and Sherry took the time to layer PT-141 thoughtfully with my TRT protocol. The integrated approach mattered."
"What I appreciated was the lab-driven, individualized approach. SSK doesn't shortcut sexual health protocols."
From Our Founders
PT-141 occupies a unique place in sexual health protocols because of its central nervous system mechanism. For patients whose concerns are not primarily vascular, the melanocortin pathway can be a meaningful addition. Patient selection, hormonal context, and dose calibration matter substantially.
PT-141 requires careful compounding and dose calibration, particularly given its cardiovascular profile and drug interaction considerations. Every vial we dispense at SSK Longevity reflects the kind of pharmacist involvement that compounded sexual health protocols genuinely deserve.
