Melanotan 2 Introduction:
Melanotan 2 (also referred to as Melanotan II) is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis, a process responsible for pigmentation of the skin. This peptide hormone, called alpha-Melanocyte stimulating hormone or MSH, activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido via these melanocortin receptors. As a result, Melanotan 2 has been shown in studies to exhibit appetite suppressant, lipolytic, and libido-enhancing effects in addition to promoting skin tanning. Melanotan 2 has been researched extensively for use in protecting against the harmful effects of ultraviolet radiation from sunlight due to its melanogenesis-stimulating properties.
Additionally, Melanotan 2 and a similar synthetically produced variant, known as PT-141, have been studied at length as a potential remedy for the treatment of sexual dysfunction; specifically, male erectile dysfunction.
Why Melanotan II
For a bodybuilder planning to compete on stage, there is a considerable amount of time and attention to detail committed before they are ready to compete. Being muscled up and defined is only accentuated by a nice tan to make lines and definitions pop out and become more evident to viewers and judges. Enter the heptapeptide Melanotan II, now bodybuilders can actually protect themselves from over exposure to the sun while boosting melanin. This results in a darker and more tanned complexion. When Melanotan II is added to a peptide protocol leading up to a show, it will boost melanin levels, resulting in tanner skin; in addition, it will increase fat loss and muscle hardness.
Melanotan 2 Studies and Further Information
Melanotan and Melanotan 2 are both analogs of the peptide hormone alpha-melanocyte stimulating hormone (α-MSH) that tend to induce skin tanning. Unlike Melanotan 1, Melanotan 2 has been shown to have aphrodisiac properties, the additional effect of increasing libido. Melanotan 2 is a cyclic heptapeptide analog of the alpha-melanocyte stimulating hormone (a-MSH).
The effects of Melanotan 2 on the diet and food intake of the laboratory mice have also been investigated. It has been demonstrated that the central melanocortin (MC) has been activated by melanotan 2 when fed and induced in the mice. The six-day treatment of Melanotan 2 has shown that the peptide actually reduced the body weight and the adipose tissue in the viscera of the mice and suppressed the caloric intake of the organism. This has implications in clinical applications of the possible treatment to reduce carbohydrate or calorie intake especially for the overweight and the obese. Furthermore, the same study has also demonstrated that there was a sustained increase in the available oxygen consumption in obese animals. Melanotan 2 also helped reduced the level of serum in-sulin and the cholesterol levels when compared with the control treatments. Furthermore, it has been suggested that melanotan 2 actually lowers the level of acetylcholine A caboxylase expression and even prevented the reduction of carnitine and palmitoltransferase I mRNA in muscle-type tissues by pair-feeding in the muscles of the obese rats. Moreover, the Melanotan 2 peptide actually increased the fat catabolism in the muscles and even improved the cholesterol metabolism
