The 'hormonal + central' framing in research protocols reflects two distinct intervention points. PT-141 operates at the central nervous system level. Specifically within hypothalamic nuclei that integrate sen…
PT-141 (bremelanotide) is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone ( -MSH) with selective agonist activity at melanocortin MC3R and MC4R receptors. These receptors are densely expre…
Primary Mechanism MC4R agonist in paraventricular nucleus → dopamine modulation in reward centres GPR54 agonist on GnRH neurons → LH/FSH pulse Same as kisspeptin-10, longer half-life in circulation Dual pathwa…
Primary Target Melanocortin MC4R in paraventricular nucleus KISS1R (GPR54) on GnRH neurons in arcuate nucleus Dual pathway: CNS arousal + HPG axis activation PT-141 alone for arousal dysfunction; kisspeptin al…
PT-141 Melanocortin agonist MC3R, MC4R (hypothalamus, brainstem) 45–60 4–6 hours None. Central only Activates arousal circuits; no LH/testosterone elevation Kisspeptin-10 GnRH secretagogue GPR54 (GnRH neurons)…
