Mechanism of Action

Melanotan 2 is a cyclic lactam analogue of alpha-MSH, cyclo[Nle4,Asp5,D-Phe7,Lys10]-alpha-MSH(4-10), that binds four melanocortin receptors with high affinity: MC1R, MC3R, MC4R and MC5R. MC1R is expressed on melanocytes and couples to cAMP; MC3R and MC4R are central receptors involved in energy homeostasis; MC5R is expressed in exocrine tissue. The lack of receptor selectivity distinguishes it from PT-141, which was derived from the same scaffold with a narrower MC3R and MC4R profile.

Scientific Research

Why Researchers Choose Melanotan 2

Melanotan 2 (MT-II) is the reference tool compound for the melanocortin system, because a single cyclic alpha-MSH analogue engages four receptors at once. That breadth makes it a frequent subject across several research areas:

  • UV-independent melanogenesis and photoprotective pigmentation via MC1R
  • MC4R signalling in sexual motivation and erectile function
  • MC3R and MC4R signalling in energy-homeostasis models
  • Receptor-selectivity comparisons against the linear analogue PT-141 (bremelanotide)
  • Structure-activity work on cyclic versus linear melanocortin peptides

Melanotan 2 Receptor Pharmacology

The four melanocortin receptors relevant to MT-II research and the effect each one mediates:

ReceptorPrimary LocationMT-II Effect
MC1RMelanocytes, skinMelanogenesis, photoprotection
MC3RHypothalamus, limbicEnergy balance, anti-inflammatory
MC4RHypothalamus, brainstem, spinal cordCentral energy homeostasis, reproductive signalling
MC5RExocrine glands, adrenal cortexExocrine secretion

MC1R is expressed on melanocytes, while MC3R and MC4R are central receptors. The absence of receptor selectivity is the defining pharmacological feature of MT-II.

Scientific Significance

Melanotan 2 was the compound that established MC4R as the central receptor for mammalian sexual function. A 1998 Science study showed that MT-II induced spontaneous erections in MC4R-expressing rodents and that knocking out MC4R abolished the effect. That finding led directly to three developments:

  1. The design of PT-141 (bremelanotide) as a selective MC4R agonist
  2. PT-141’s FDA approval as Vyleesi for hypoactive sexual desire disorder (HSDD)
  3. Sustained MC4R research across obesity, sexual dysfunction and cardiovascular regulation

As the molecule that opened up MC4R biology, Melanotan 2 remains a reference compound in melanocortin receptor research. It is not an approved medicine.

Reconstitution and Storage

Reconstitution: use bacteriostatic water; swirl gently until dissolved, do not shake. After reconstitution: keep refrigerated (2-8°C), protect from direct light, and use within 30 days.

Been a solid bronze for a year. Potent MT2. Highly recommend, ordered many times. Glowing skin and a noticeable boost in libido.

Works great. And the service is the best.

Works great, it's legit. Delivery in less than 2 days to Pathum Thani. I recommend taking cetirizine 30 minutes before pinning to avoid nausea.

I arrived from Russia very fair-skinned and was badly sunburnt after my first week here. I tried another company's Melanotan and had to stop using it after a few days because it made me nauseous and the results were poor. A friend recommended Milo Lab, and after purchasing this product, the results were amazing. My skin was a golden brown, I had no side effects, and overall I felt and looked fantastic. I highly recommend Milo Lab for this product - the service and packaging were also very professional, so I could tell it's not a cheap backyard operation. From Russia with love, Zhenya.
