MT2 10mg( MELANOTAN 2 )

Melanotan-2 (MT-2) is a synthetic analogue of alpha-melanocyte-stimulating hormone. Developed in the 1980s, Melanotan-2 has been shown to increase sexual arousal, reduce compulsive/addictive behavior, curb hunger and increase melanin production. Research has shown the peptide to stimulate melanocytes therefore producing increased skin pigmentation and may help to combat autism when used during early childhood development.

Melanotan II is a synthetic analogue of the peptide hormone α-melanocyte-stimulating hormone (α-MSH) that stimulates melanogenesis and increases sexual arousal.

It was under development as drug candidate for female sexual dysfunction and erectile dysfunction but clinical development ceased by 2003, and as of 2018, no product containing melanotan II was marketed and all commercial development had ceased.

Unlicensed, untested, or fraudulent products sold as "melanotan II" are found on the Internet, and purported to be effective as "tanning drugs", though side effects such as uneven pigmentation (it makes already uneven pigmentation more noticeable), new nevi (moles), and darkening or enlargement of existing moles have been reported and have led to medical authorities discouraging its use. There has been no scientific study into the long term and permanent side effects the use of this peptide may cause.

Synthesis

In the synthesis of melanotan II, an ε-amino group of lysine and an γ-carboxy group of aspartic acid have their orthogonal protection removed before undergoing a carbodiimide mediated lactamization, leading to an intermediate. This intermediate, when attached to N-acetylnorleucine, forms melanotan II. The entire process can be accomplished in 12 steps with an overall yield of 2.6%, and the product is more than 90% pure without preparative chromatography.

Mechanism of action

Melanotan II acts as a non-selective agonist of the melanocortin receptors MC1, MC3, MC4, and MC5.

Melanotan II produces melanogenesis by activation of the MC1 receptor, whereas its clinically documented sexual effects are thought to be related to its ability to activate the MC4 receptor (though the MC3 is thought to also possibly be involved).

Other effects of melanotan II, mostly regarded as adverse effects, include flushing, nausea, vomiting, stretching, yawning, and loss of appetite (the last via activation of MC4).
