What is MT-2 (Melanotan II) used for?
MT-2 (Melanotan II) is most commonly used for users wanting deeper pigmentation than MT-1 delivers; people who specifically want the libido side effect; anyone who tolerated the nausea/flush profile in past use. Tans your skin harder than MT-1 and also bumps libido, but brings rougher side effects. A less selective alpha-MSH analog. Human evidence for MT-2 (Melanotan II) is limited, so these are the goals people pursue with it, not guaranteed outcomes.
