MT2 Pen

MT‑II (Melanotan II) is a synthetic peptide analog of α‑melanocyte‑stimulating hormone (α‑MSH). It was originally investigated for its ability to stimulate melanin production (tanning) and later studied for central nervous system effects on sexual arousal and libido.

☀️ Skin Pigmentation & Melanin Production

MT‑II activates melanocortin receptors (especially MC1R) in melanocytes, leading to increased melanin production and progressive skin tanning in humans over multiple doses.
