Read our page about everything to know about Melanotan [name1] Melanotan’s peptide structure is almost the same as our endogenously produced melanocyte-stimulating hormone. MT is an agonist of the melanocortin-1 receptor (located on melanocyte cells) and when this receptor is triggered it eventually will cause tanning of the skin. MT 1 does not bind well to other receptors. Melanotan 2 has a shorter sequence of amino acids and also has a slightly different form then Melanotan 1. Because of this subtle change, binding at receptors other than the melanocortin-1 receptor is greater than that of Melanotan 1. This receptor binding on other receptors then the melanocortin-1 receptor results in some effects with MT-II usage that the user will not notice in MT1 usage.
MT2 also binds to the melanocortin-3 and 4 receptors and this binding will cause increases in sexual arousal. Which of the two is better? Because the amino-acid sequence is shorter in the case of melanotan2, there are more MT2 peptide chains available compared to MT1 on an mg for mg basis.
