Melanotan 2 Nasal Spray 10MG

What Is Melanotan 2 Nasal Spray?

Melanotan 2 Nasal Spray 10mg is a research-grade intranasal formulation of Melanotan II (MT-II) supplied by Arma Peptides for controlled laboratory investigation. Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH), engineered for enhanced receptor binding affinity and resistance to enzymatic degradation relative to the native linear peptide. The nasal spray format presents the active compound in a pre-constituted aqueous solution, providing a standardised intranasal delivery vehicle for experimental mucosal absorption and bioavailability research.

MT-II acts as a non-selective agonist across multiple melanocortin receptor subtypes — MC1R, MC3R, MC4R, and MC5R — with binding affinities documented in multiple in vitro receptor characterisation studies. The breadth of receptor activity has made Melanotan 2 Nasal Spray a frequently cited compound across pigmentation biology, CNS arousal pathway research, and melanocortin receptor pharmacology. Researchers interested in the lyophilised vial format may also consider Melanotan 2 10mg from Arma Peptides.

Mechanism of Action

Melanotan II binds and activates melanocortin receptors via a cyclic lactam backbone that confers significantly greater receptor affinity than the native α-MSH linear sequence. MC1R activation in melanocyte models stimulates eumelanin synthesis via the cAMP–PKA–MITF signalling axis. MC4R activation in hypothalamic nuclei modulates downstream dopaminergic and oxytocinergic neurotransmission pathways relevant to CNS arousal and energy balance research. MC3R and MC5R activity has been investigated in the context of metabolic regulation and exocrine gland function respectively.

The intranasal route explored in nasal spray research models provides direct access to nasal mucosa-associated lymphoid tissue and potential olfactory pathway absorption, making Melanotan 2 Nasal Spray a distinct pharmacokinetic model from subcutaneous peptide delivery and a useful comparator in route-of-administration studies.

Melanotan 2 Nasal Spray Research Overview

Melanotan 2 Nasal Spray has been investigated in preclinical research examining intranasal peptide absorption, melanocortin receptor pharmacology, and comparative bioavailability relative to parenteral administration routes. Studies have documented MC receptor binding at all five subtypes, with particular focus on MC1R-mediated pigmentation responses and MC4R-mediated CNS pathway modulation in rodent models.

Additional preclinical research has examined the compound in energy homeostasis, appetite suppression, and peripheral metabolic signalling models. Structural and pharmacological data for Melanotan II are indexed at PubChem (NIH), bioactivity records are available in the ChEMBL database (EMBL-EBI), and peer-reviewed literature is indexed at NCBI.
