Freezable? ✅ Yes

Melanotan II is a synthetic analog of the peptide hormone alpha-melanocyte-stimulating hormone (α-MSH). It is primarily known for its ability to induce skin tanning without excessive UV exposure.

Biological Activity

It acts as a non-selective agonist of the melanocortin receptors (MC1, MC3, MC4, MC5). MC1 activation is responsible for skin pigmentation, while MC4 activation influences sexual arousal and appetite suppression.
