Melanotan 2 (MT2) 10mg is a synthetic peptide designed to stimulate melanin production in the skin, promoting a natural-looking, long-lasting tan. Popular among those seeking a sun-kissed glow without excessive UV exposure, MT2 also helps reduce sunburn risk by enhancing the body’s natural pigmentation. Ideal for individuals looking for safer tanning alternatives.

What Is Melanotan 2 (MT-2)?

Melanotan 2 (MT-2) is a synthetic version of human alpha-melanocyte-stimulating hormone (a-MSH). It was originally developed in the 1980s, at the University of Arizona, after it was found that a-MSH caused sexual arousal in rodents as well as darkening of the skin. Originally designed as a sunless tanning option, MT-2 was eventually found to have a wide range of effects such as: in

• increasing sexual arousal,
• promoting tanning or skin pigmentation,
• reducing compulsive behavior,
• controlling addiction,
• fighting hunger,
• reducing glucagon production, and
• reversing features of autism.

Melanotan 2 Research

Melanotan 2 and Melanocortin Signaling

Melanotan 2 produces its effects by binding with melanocortin receptors. There are five known melanocortin receptors, each with different function. MT-2 is known to bind primarily to MC-4R and MC-1R, but also binds weakly to MC-3R.

• MC-1R: Found on melanocytes, stimulation of MC-1R causes darkening of the skin and hair.
• MC-2R: Found in the adrenal glands, MC-2R binding promotes the secretion of adrenal hormones, such as cortisol.
• MC-3R: MC-3R is involved in appetite control and energy regulation, but little else is known about this receptor.
• MC-4R: Stimulation of MC-4R causes changes in feeding and sexual behavior. It also affects male erectile function and energy homeostasis.
• MC-5R: MC-5R is expressed on sweat glands and pancreatic islet cells.

Melanotan 2 and Autism

The newest research finding for MT-2 indicates that the peptide can reverse certain autistic features in a commonly used mouse model of autism spectrum disorder (ASD). There is no treatment for the condition, but recent search has indicated that oxytocin therapy may be useful in mitigating some of the behavioral problems associated with ASD. Using a mouse model of maternal immune activation known to lead to autism, researchers investigated whether MT2, which is known to stimulate oxytocin release, could counteract ASD or reduce common ASD behviors. Their research revealed that administration of MT-2 reverses the decreased communication, impaired social interaction, and repetitive behaviors associated with autism in this particular model. In fact, the researchers found that MT-2 administration increased the expression of oxytocin receptors in specific parts of the brain, suggesting a direct correlation between oxytocin signaling in those areas and ASD-specific behaviors[1].

Melanotan 2 and Hunger

There is good evidence to suggest that MT-2 can reduce fat storage and hunger behavior in animal models. Researchers have found that the melanocortin-4 receptor (MC-4R) plays a role in food preferences and intake and that MT-2 is a potent agonist of MC-4R. Administration of MT-2 to mice causes significant reductions in how much food they consume, but also changes their preference for fatty foods. Mice given MT-2 ignore fatty foods, which they would otherwise prefer. Similarly, mice devoid of the MC-4R receptor consume fatty foods almost exclusively and are immune to the effects of MT-2.

The effects of MT-2 are similar to those of the hormone leptin, sometimes called the satiety hormone because it reduces cravings and food intake. Leptin, however, has never been useful in the treatment of obesity, even in individuals who are leptin deficient. This is likely because there are two pathways for satiety, called leptin-dependent and leptin-independent pathways. Research suggests MT-2 is more effective in stimulating both pathways and thus may be a more effective exogenous treatment for reducing hunger. This latter finding has been bolstered by the discovery that thyrotropin-releasing hormone (TRH) gene expression, which has long been known to play a role in the leptin-satiety pathway, is also affected by MC-4R stimulation [5]. Both MT-2 and leptin are thought to cause an increase in TRH expression in the paraventricular nucleus of the hvpothalamus. a region of the brain associated with satiety and food intake, but only MT-2 crosses into the central nervous system in concentrations high enough to have an effect on TRH expression

Melanotan 2 and Diabetes

The pathogenesis of diabetes is defined by high blood sugar levels, hypersecretion of glucagon, and the production of ketone bodies. It has been known for some time that leptin counteracts these factors by increasing the uptake of glucose, suppressing glucagon production, and interfering with the pathway that leads to ketone body formation. These actions do not depend on insulin and thus leptin signaling is being actively investigated as an alternative means by which diabetes might be treated.

Research has revealed that leptin’s effects on blood sugar are regulated through melanocortin receptors and that MT-2 produces similar effects. This is significant because leptin has its primary effects in the brain but does not cross the blood-brain barrier as readily as MT-2. Thus, exogenously administered leptin does not reach the CNS in substantial quantities, a fact that reduces its effectiveness as a drug and hands an advantage to MT-2 even though the effects of the two peptides on melanocortin receptors are nearly identical.

Melanotan 2, Impulse Control and Alcohol Intake

In keeping with the idea that MT-2 may affect oxytocin signaling and thus behavior in ASD, research also reveals that the MC-4R receptor may play a role in impulse control. Past studies in rats have shown that administration of MT-2 reduces alcohol intake and increases water intake even in rats that prefer alcohol. More recently, research has revealed that melanotan-2 works synergistically (boosting efficacy more than seven-fold) with naltrexone to blunt binge-like ethanol intake in mice.

Melanotan 2 and Erectile Dysfunction

Erectile dysfunction (ED) is often attributed to vascular issues and can be effectively treated in a majority of men via sildenafil (Viagra) and other drugs that improve blood flow by reducing vascular resistance. Not all ED is due to vascular issues, however, and so sildenafil and similar drugs are ineffective in a small percentage of men and in the vast majority of women who suffer from hypoactive sexual desire disorder. It has long been known that MT-2 is an effective treatment for ED, but research suggests that it may have more wide-ranging application than drugs like sildenafil due to its actions in the central nervous system. In a study of men who had failed treatment with Viagra, eighty percent responded to MT-2 treatment[10]. MT-2 has been actively investigated in the past as a treatment for both male and female sexual desire disorders.

Future MT-2 Research

MT-2 is a heavily researched peptide, particularly regarding human behavior, sexual desire, and impulse control. The peptide, in various forms, has been investigated in clinical trials, though problems with routes of administration have forced scientists back to the drawing board. There is active and ongoing research into the benefits of this particular peptide.
MT-2 exhibits minimal to moderate side effects, low oral and excellent subcutaneous bioavailability in mice. Per kg dosage in mice does not scale to humans.
