Melanotan 2 (MT2) 10mg Nasal Spray – 100mcg/Spray

Melanotan II (MT-2) is a synthetic analogue of alpha melanocyte stimulating hormone (α-MSH), a naturally occurring peptide derived from pro opiomelanocortin (POMC) that acts on melanocortin receptors distributed across multiple biological systems. Hudson Science’s formulation delivers 10mg total MT-2 at 100mcg per metered spray in a nasal delivery system; a non invasive administration route that provides consistent, precise dosing without the preparation and administration variables associated with reconstituted injectable peptide formats.

Melanotan II’s research profile spans several distinct melanocortin receptor pathways. Its primary documented activity involves MC1R (melanocortin 1 receptor) stimulation, driving melanogenesis; the production of eumelanin in melanocyte cells which has made it a frequently studied compound in pigmentation biology and photoprotection research. MC3R and MC4R activation produces additional research relevant effects documented across appetite regulation, energy homeostasis, and sexual function pathways;  the MC4R activity in particular has generated significant research interest in studies examining central melanocortin signaling in metabolic regulation and hypothalamic appetite control. This multi receptor activity profile across MC1R, MC3R, and MC4R makes Melanotan II a uniquely versatile research tool in comparative melanocortin receptor pharmacology.

The nasal spray format is a pharmacokinetically relevant delivery choice for Melanotan II. As a centrally acting peptide with hypothalamic MC4R targets, the nasal route’s proximity to the olfactory epithelium and potential olfactory nerve pathway access to the central nervous system is a meaningful research variable compared to peripheral subcutaneous injection; supporting comparative intranasal versus parenteral delivery studies examining melanocortin peptide CNS bioavailability and receptor engagement across different administration routes.
