Melanotan 2 Peptide – Premium Research-Grade Melanocortin Agonist (MT-II)

Melanotan 2 (MT-II) is a high-purity synthetic cyclic heptapeptide supplied exclusively for laboratory and scientific research. Developed as a potent analog of the naturally occurring α-melanocyte-stimulating hormone (α-MSH), Melanotan 2 has become a widely studied compound in melanocortin receptor research, with published investigations spanning pigmentation, neuroprotection, appetite regulation, and neurosignaling pathways. Each batch is manufactured under strict quality controls, providing researchers with a consistent and dependable compound for experimental work.

What is Melanotan 2 Peptide?

Melanotan 2 is a laboratory-engineered analog of α-melanocyte-stimulating hormone, structured as a cyclic heptapeptide. Its ring-shaped configuration appears to give the molecule a modified binding profile toward the receptors engaged by the endogenous hormone, along with a more prolonged metabotropic activity than linear MSH analogs. Beyond its well-documented potential to stimulate melanogenesis — the production of melanin pigment within dermal cells — research suggests Melanotan 2 may exhibit increased affinity toward additional receptors involved in regulating appetite and various forms of arousal. This broad receptor profile has made MT-II a versatile tool compound across multiple fields of biomedical investigation.

Key Research Benefits & Effects

• Melanogenesis Stimulation: Through interaction with the MC1R receptor on melanocytes, Melanotan 2 may increase eumelanin synthesis, producing darker epidermal pigmentation in research models without ultraviolet exposure.
• Neuroprotective Potential: In murine models of peripheral nerve injury, Melanotan 2 appeared to support sensory function recovery and partially shield nerves from chemotherapy-induced neurotoxicity.
• Nerve Regeneration Support: Studies suggest the peptide may promote neurite outgrowth and nerve sprouting in damaged regions via MC4 receptor-mediated pathways.
• Arousal Neurosignaling: A clinical study reported increased arousal-related neural signaling in more than 80% of cases, compared to roughly 20% with placebo, likely mediated through MC4 receptors.
• Neurodevelopmental Modulation: Research indicates Melanotan 2 may stimulate oxytocin-releasing hypothalamic circuits, potentially influencing social cognition pathways involving serotonin, glutamate, dopamine, and GABA.
• Appetite Regulation Pathways: Through potential binding at MC3 and MC4 receptors, the peptide offers a research avenue for exploring melanocortin-driven appetite and energy-balance mechanisms.

How Melanotan 2 Peptide Works

Melanotan 2 is believed to act as a non-selective melanocortin receptor agonist, with the potential to bind four of the five known melanocortin receptor subtypes. Its interaction with MC1R — expressed in melanocytes of the skin, hair, and ocular tissues — may drive increased eumelanin production and darkened pigmentation. Binding at MC4R, localized in the central nervous system and hypothalamus, may engage supraspinal centers whose signals travel to sympathetic and parasympathetic pathways in the spinal cord, a mechanism researchers associate with arousal signaling. MC3R, found in tissues including the brain and placenta, has been linked to appetite modulation under experimental conditions, while the role of the widely distributed MC5R remains under investigation. This receptor-dependent versatility means the peptide's observed actions vary with receptor localization, making it a valuable subject for targeted melanocortin research.

Usage Information

• Weeks 1–2: 0.25 mg daily to gradually establish pigmentation.
• Weeks 3–4: 0.5 mg daily, adjusting based on the desired response.
• Week 5 onward: 0.5–1 mg every 2–3 days to help maintain the desired level of pigmentation.

Product Specifications

Quality & Manufacturing

Every batch of Melanotan 2 Peptide is synthesized under controlled laboratory conditions and verified through rigorous analytical testing to confirm identity, purity, and structural integrity. Standardized production protocols preserve the peptide's cyclic conformation — the structural feature responsible for its enhanced potency and prolonged activity compared to linear MSH analogs — while careful lyophilization protects stability during storage and transport. Batch-to-batch consistency ensures that research teams can depend on reproducible experimental conditions across studies.

Safety Information & Handling Considerations

• Research-Only Status: Melanotan 2 is sold exclusively for scientific and laboratory research. It must not be used for human consumption, tanning, therapeutic, diagnostic, or cosmetic purposes.
• Documented Adverse Event Reports: Published literature includes a case report associating Melanotan II with renal infarction, underscoring why this compound must remain confined to controlled research settings.
• Proper Handling: Use appropriate personal protective equipment and follow institutional laboratory safety procedures when handling, reconstituting, or disposing of the peptide.
• Storage Sensitivity: Like all peptides, Melanotan 2 may degrade under improper storage or repeated freeze-thaw cycles — always adhere to recommended storage guidelines.
