Melanotan II 10mg
Cyclic α-MSH analog — tanning, libido enhancement, and appetite regulation.
MT-2 — Melanocortin System Research
Across melanocortin-receptor research, Melanotan II (MT-2) is a synthetic cyclic analog of α-MSH that acts on MC1R, MC3R, and MC4R. It stimulates melanin production for UV-protective tanning, enhances libido through MC4R activation, and may suppress appetite. It produces faster and stronger tanning results than Melanotan I due to its broader receptor activation.
Primary research applications for MT-2 include rapid melanin production for sunless tanning, libido enhancement via mc4r, appetite regulation support, uv damage protection mechanisms. As a Melanocortin compound, it is studied in the context of melanocortin, tanning, melanin — areas where its mechanism of action has the most direct relevance in preclinical models.
In standard research protocols, MT-2 is administered at 0.5–1 mg subcutaneous titrate slowly, with a half-life of 30–60 minutes. This product is supplied by Phiogen as lyophilized powder with independent third-party Certificate of Analysis (COA) documentation confirming 99%+ purity and correct molecular identity on every batch. Melanotan II 10mg is sold strictly for laboratory and educational use only — it is not FDA-approved for human therapeutic use and is not intended for human consumption, clinical application, or use in animals.

Frequently Asked Questions
What melanocortin receptors does MT-2 activate and what are their functions?
MT-2 is a non-selective agonist at all five melanocortin receptors. MC1R mediates pigmentation in melanocytes. MC2R is the primary ACTH receptor in the adrenal gland. MC3R and MC4R are expressed in the brain and regulate energy homeostasis, arousal, and feeding behavior. MC5R is found in exocrine glands and immune cells. MT-2's broad activity across this receptor family produces the composite pharmacological profile observed in studies.
How does MT-2 stimulate melanogenesis?
Activation of MC1R on cutaneous melanocytes by MT-2 stimulates adenylyl cyclase and elevates cAMP, which activates protein kinase A and downstream transcription factors including MITF (microphthalmia-associated transcription factor). MITF drives expression of enzymes in the melanin synthesis pathway including tyrosinase, resulting in increased eumelanin production. This process occurs independent of UV radiation, though UV light potentiates the response by damaging DNA and activating pro-melanogenic signaling.
How does MT-2 differ from alpha-MSH structurally?
Alpha-MSH is a linear 13-amino acid peptide with rapid enzymatic degradation in vivo. MT-2 is a cyclic 7-amino acid analog that incorporates a His-D-Phe-Arg-Trp pharmacophore responsible for melanocortin receptor binding, with cyclization that confers resistance to protease digestion and extends bioavailability. This structural optimization results in greater potency and duration of action compared to native α-MSH in pharmacological studies.
Applications & Benefits
🔬 Mechanism of Action
Melanotan II (MT-2) is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone (α-MSH) that acts as a non-selective agonist at all five melanocortin receptor subtypes (MC1R through MC5R). Its primary studied effects include potent melanogenesis via MC1R activation on melanocytes (stimulating eumelanin production), CNS-mediated effects on arousal via MC3R and MC4R, and appetite suppression through hypothalamic melanocortin pathways. Its broad receptor activation profile distinguishes it pharmacologically from more selective analogs such as PT-141.
