Question 1

What is the difference between Melanotan I and Melanotan II?

Accepted Answer

Melanotan I selectively targets the MC1 receptor for pure pigmentation. Melanotan II is non-selective, targeting multiple receptors, which causes pigmentation, appetite suppression, and increased libido.

Question 2

How does MT-2 cross the blood-brain barrier?

Accepted Answer

Due to its cyclic structure and small molecular size, MT-2 efficiently penetrates the CNS to interact with central MC3 and MC4 receptors.

Question 3

Is Melanotan II safe for cosmetic use?

Accepted Answer

Melbourne Peptides strictly prohibits the use of MT-2 for human consumption or cosmetic tanning. It is supplied exclusively for in-vitro and laboratory research.
