Melanotan II + Gonadorelin: Central & Hormonal Sexual Health

Melanotan II is researched as a melanocortin receptor agonist with centrally mediated effects on arousal and sexual motivation through MC3R and MC4R pathways. Gonadorelin, a synthetic GnRH analog, is investigated for stimulating pulsatile LH and FSH release to support the hypothalamic-pituitary-gonadal (HPG) axis. The combination addresses sexual health through complementary central arousal signaling and hormonal baseline support.

Synergistic Effect

Dual-pathway activation

Melanotan II × Gonadorelin

Safety Notes

Melanotan II is associated with nausea, facial flushing, spontaneous erections, and increased pigmentation with UV exposure at research doses. Gonadorelin is well-characterized in clinical endocrinology for HPG axis evaluation. No formal combination study data exists.

PT-141 + Kisspeptin-10: Sexual Health
Sexual HealthPreclinical
A central and upstream sexual function stack combining PT-141's direct melanocortin receptor activation for arousal with kisspeptin-10's hypothalamic stimulation of the HPG axis. PT-141 enhances sexual desire and performance at the CNS level independent of vascular mechanisms, while kisspeptin-10 drives pulsatile LH and GnRH release to support the hormonal underpinning of libido. The two peptides target sexual function at different levels of the neuroendocrine hierarchy.
