Melanotan II + PT-141 Stack (Dual-Vial Melanocortin Kit)
Analytical Standards & Laboratory Handling
Verified laboratory protocols, reconstitution parameters, and handling guidelines.
Pharmacological Profile & Mechanism of Action
What it is: A dual-action melanocortin agonist research stack pairing Melanotan II (10mg cyclic lactam) and PT-141 / Bremelanotide (10mg synthetic heptapeptide) in two separate sterile analytical vials.
How it works: Melanotan II drives peripheral cutaneous melanogenesis via MC1 receptor stimulation to induce deep photoprotective tanning while mildly stimulating central sexual arousal. PT-141 is a selective downstream metabolite that binds directly to central nervous system MC4 and MC3 receptors in the medial preoptic area (MPOA) of the hypothalamus, modulating dopamine neurotransmission to stimulate desire and erectile response without PDE5 vascular inhibition.
CRITICAL LABORATORY RECONSTITUTION & ASSAY HANDLING: Reconstitute both vials separately. Melanotan II is dosed as an escalating protocol; PT-141 is dosed 1–3 hours prior to evaluation sessions.
Compound & Molecular Specifications
Certificate of Analysis StandardsFrequently Stacked with Melanotan II
Clinically verified combinations activating complementary physiological pathways without receptor competition.
PT-141 (Bremelanotide)
Melanotan II provides systemic melanin upregulation via MC1R/MC4R, while PT-141 (Bremelanotide) selectively acts centrally on hypothalamic MC4R to trigger rapid erectile and sexual arousal pathways without cardiovascular vasoconstriction.
