What is Melanotan 2 Pen?

Melanotan II is a cyclic lactam analogue of alpha-MSH acting at melanocortin receptors, studied in pigmentation and receptor-binding research.

The pen is filled at a fixed concentration and light-protected in packaging from the point of manufacture, addressing the light-sensitivity that lyophilised MT-2 requires researchers to manage manually.

Storage & handling
