Melanotan 2 is a type of peptide called a melanotropin peptide which is an analog of the alpha-melanocyte stimulating hormone. This peptide is created and circulated within the skin. Synthetic Melanotan 2 is designed to tan and darken skin.
Melanotan 2 is a smaller and more potent than melanotan 1,it targets more melanocortin receptors. This new peptide has a protective ring of amino acids which further seperates it from the linear style peptide of melanotan 1, which ensures better absorption. Melanotan 2 is in a class of peptide hormone known as Melanocortins (MCs). Melanocortins (MCs) are multifunctional peptide hormones that regulate a diversity of physiological functions. MCs have been implicated in sexual function in animals. It is a cyclic lactam analog of -MSH with the amino acid sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2.
Because of its effect on fat loss, tanning peptide is also used to aid in weight loss. Since the melanocortin system is important for controlling body weight, the use of melanotan increases oxidation in fatty acids which improves insulin sensitivity, requiring less food to feel full and helps the body flush out fats. There are many who make use of melanotan: fitness enthusiasts and bodybuilders along with some athletes tend to use these types of peptides in order to increase the efficiency of their training regimen. This is because of the melanotans ability to store energy within cells for easy access by the body, making it easier for the body to use them during training.
Because melanotan treatments are so effective (around 1,000 times more potent than naturally occurring melanotropin), many people think that they can begin a melanotan therapy and will be immune to the harmful effects of the sun. Those with blonde or red hair, especially those who are very pale should be careful and protect themselves with sunglasses, sunscreen and basic protections when going out in the sun for extended periods of time. Melanotan requires a bit of patience but users will see dramatic results in longer time.
Melanotan comes freeze dried and sealed in a multi-use sterile vile which is injected under the skin where it binds to melanocortin receptors. These receptors influence things like pigmentation, appetite, skin inflammation, and sexual function. For practical purposes, this means that those that have fair skin, can achieve a rich, natural-looking tan even if they have an allergy to sunlight. This also means that these peptides make one of the best defenses against skin cancer available, all without spending years trying to develop a tan that will protect the skin.
When taking melanotan 2 to darken the skin, its important to remember that the tanning effect is a side effect of the peptide. When UV damage occurs in cells, the body responds by dispatching cells to repair this damage which then tan to protect the skin from further damage. This means that the users body is not growing darker but is in fact tanning naturally with help from the peptide.
