MT-2 (Melanotan 2 Acetate): Product Information and Research Overview
Melanotan 2 Acetate, commonly referred to as MT-2, is a synthetic analogue of the naturally occurring peptide hormone alpha-melanocyte-stimulating hormone (α-MSH).
It is primarily known for its ability to stimulate melanin production, which results in skin tanning.
MT-2 is often used by individuals seeking a darker complexion without excessive sun exposure.
How Does MT-2 Work?
MT-2 works by binding to melanocortin receptors in the body, particularly the MC1R receptor, which stimulates the production of melanin in the skin.
This results in:
Increased pigmentation (tanning)
Reduced risk of sunburn
Enhanced photoprotection from UV damage
Besides its tanning effects, MT-2 can also interact with other melanocortin receptors (MC3R, MC4R), which may influence libido, appetite, and energy levels.
Common Uses of MT-2
Cosmetic tanning
Protection against UV radiation
Potential sexual health applications (due to reported libido-enhancing effects)
Research into appetite control and obesity

-
Loading phase: 250–500 mcg daily until desired pigmentation is achieved
-
Maintenance phase: 250 mcg every 2–3 days
Dosage should always be tailored individually and used with proper medical oversight.
