Melanotan 2



Buy Melanotan 2 for Sale – Product Information

Melanotan 2 is a synthetic analogue of alpha-melanocyte-stimulating hormone. This hormone stimulates skin pigmentation to protect it from the harmful effects of UV rays. It also plays an important role in sexual arousal and regulating inflammation and reproductive function.

Melanotan 2 has also exhibited tanning activity in clinical trials. Research has shown this peptide to cause erections in men with erectile dysfunction, stimulate sexual desire (libido) in females, cause weight gain, and combat autism when given during early childhood development.

What is Melanotan 2?

Melanotan 2 is a non-selective melanocortin-receptor agonist, meaning it binds to melanocortin receptors in the body. It is a synthetic analog of α melanocyte-stimulating hormone (a-MSH), which increases sexual arousal and regulates inflammation and reproductive function.

Melanotan II was first synthesized at the University of Arizona in the 1990s. It shouldn’t be confused with Melanotan I, an FDA-approved drug for a specific disease. Research has shown that MT-II is much more potent than MT-I and can induce pigmentation at lower doses. [R]

Clinical trials have shown that MT-II can induce penile activity (erections) in men with erectile dysfunction. This peptide has also exhibited the ability to enhance sexual function in females. In a clinical trial, MT-II increased sexual desire and genital arousal levels in females. [R]

Preclinical studies have also investigated the potential effects of MT-II. These studies have shown that MT-II might reduce body weight without needing long-term caloric restriction. In a mice model of autism, this synthetic peptide reversed features of the disorder. [R][R]


How does Melanotan 2 Work?

Melanotan II works by binding to melanocortin receptors (MCRs).

MCRs are a family of G-protein coupled receptors that perform various functions. There are five of them in your body (MC1R, MC2R, MC3R, MC4R, and MC5R). They regulate pigmentation, inflammation, childhood growth, puberty onset, and lean mass accrual. [R]

According to research, Melanotan II is a potent agonist of four MCR genes, including: [R]

  • MC1R – plays an important role in normal pigmentation. [R]
  • MC3R – linked to childhood growth, the buildup of lean mass, and the timing of puberty [R]
  • MC4R – regulates sexual function, reproduction, and many other functions [R]
  • MC5R – necessary for normal sebum production. [R]


Melanotan 2 Research

What follows is a summary of existing research on MT II. The information presented in this section is for educational purposes only and doesn’t constitute medical advice. Behemoth Labz sells Melanotan 2 for scientific research purposes only.


1) Melanotan 2 and Erectile Dysfunction

In a double-blind placebo-controlled crossover study, MT-II treatment (0.025 mg/kg) led to penile erections in 17 out of 20 men with erectile dysfunction. Notably, the increase in penile activity was achieved in the absence of sexual stimulation. [R]

Another placebo-controlled study investigated the effects of MT-II treatment on 10 men with ED. Final results from the study reported that this synthetic melanotropic peptide is a potent initiator of erections in men with psychogenic erectile dysfunction. [R]


2) Melanotan 2 and Tanning

Melanotan II has exhibited tanning properties.

In a pilot phase 1 clinical study, alternating day Melanotan II treatment produced increased pigmentation in the face, upper body, and buttocks. These results demonstrate that this synthetic peptide has tanning activity in humans via subcutaneous injection. [R]


3) Melanotan 2 and Sexual Desire in Females

Research has shown that MT-II can enhance sexual function in females.

This synthetic peptide has been documented to increase women’s sexual desire and genital arousal level. Furthermore, since it works differently from other sexual-enhancement drugs (which don’t act at the level of the brain), MT-II can elicit a rather natural sexual response. [R]


4) Melanotan 2 and Weight Loss

MT II can cause weight loss without affecting food intake or energy expenditure.

A mice study investigating the effects of MT-II on energy homeostasis found that this synthetic peptide reduced body weight without causing decreased appetite. Animals who received MT II had 40 percent smaller fat pads in the abdominal area and peripheral tissues than those who did not. [R]


5) Melanotan 2 and Autism

In an adult male mouse model of autism, MT-II was found to be an effective agent for improving autism-like behavioral deficits. The researchers hypothesized that MT-II as a promising approach for individuals with before-birth exposure to infection. [R]

What is notable is that the above effects of Melanotan II were observed upon treatment of adult mice. This suggests that the potential benefits of MT-II treatment may not be limited to a small therapeutic window during early development. [R]


6) Melanotan 2 and Diabetes

Two preclinical studies have shown that MT II treatment increased insulin sensitivity and improved glucose tolerance in mice. [R][R]

High insulin sensitivity benefits your health by allowing the body to use blood glucose more effectively, thereby reducing blood sugar. Improved glucose tolerance (how quickly glucose is cleared from the blood) is crucial to maintaining normal blood sugar levels.


7) Melanotan 2 and Alcohol Abuse

Research has shown that the administration of MT II reduces voluntary alcohol consumption in mice. Data from the study suggests that MT-II antagonizes melanocortin receptor 3 (MC3R) to exert protective effects against binge-like ethanol drinking (alcohol abuse). [R]

MT-II’s potential ability to prevent and/or treat alcohol abuse could be backed by the fact that the activation of MC4R – the melanocortin receptor that MT I targets – has been proven to inhibit voluntary alcohol intake in adulthood in animal models. [R]


Melanotan II Safety

Clinical research has shown that nausea, yawning, stretching, and spontaneous erections are the most common side effects of Melanotan II. Speak to a licensed healthcare provider to know more about Melanotan II’s safety and efficacy.


Frequently Asked Questions

What does Melanotan II do?

Research has shown that Melanotan II enhances skin tanning or pigmentation. Pigmentation protects the skin from the harmful effects of sun exposure, such as skin cancers.


What is the half-life of Melanotan II?

Melanotan II has a relatively long half-life of approximately 2 hours. [R]


Is Melanotan-2 FDA approved?

Melanotan 2 isn’t approved by the FDA. Behemoth Labz sells MT-II for laboratory and research purposes, not for human consumption.
