MT-2

PigmentationSkin

MT-2 is a melanocortin receptor agonist studied for pigmentation, appetite, and sexual-function research.

What does it do?

Increases melanin so skin tans more easily
Can reduce the amount of sun needed for color
Often lowers appetite
Can increase libido
Color builds faster than with MT-1
Comes with more side effects than MT-1

How does it work?

Activates melanocortin receptors involved in pigment
Tells melanocytes to make more melanin
Also hits receptors tied to appetite and arousal
That broader receptor activity is why extra effects show up
Color still needs some UV or sun exposure to develop fully

What to expect?

A flush or queasy feeling is common after early doses
Freckles and moles can darken
Tan usually appears over 1 to 2 weeks with light exposure
Appetite may drop
Libido can rise more than people expect
