MT-II (Melanotan II) (10mg)

Melanocortin Peptide

Melanotan-2 is a synthetic peptide analog that activates melanocortin receptors to stimulate melanogenesis and enhance skin pigmentation, while also supporting sexual arousal and desire through central nervous system pathways—offering a dual-action approach to cosmetic tanning and sexual wellness.

The Science

What is Melanotan-2?

Melanotan-2 is a synthetic analog of alpha-melanocyte stimulating hormone (α-MSH), designed to activate melanocortin receptors throughout the body. Its primary mechanism involves binding to MC1R receptors in melanocytes, triggering increased production of eumelanin—the pigment responsible for darker skin tones. This results in enhanced tanning without prolonged UV exposure.

Beyond its cosmetic applications, Melanotan-2 also activates MC3R and MC4R receptors in the central nervous system, which play roles in sexual arousal, appetite regulation, and energy homeostasis.

Laboratory Observations

Key Observed Effects of MT-II (Melanotan II) (10mg)

Enhanced Skin Pigmentation

Stimulates melanin production for natural-looking tan without excessive UV exposure—ideal for individuals with fair skin seeking enhanced pigmentation or preparing for sun exposure.

Photoprotection

Increased melanin provides natural UV protection, potentially reducing sunburn risk and long-term photodamage—offering both cosmetic and protective dermatological benefits.

Libido Enhancement

Activates MC4R receptors involved in sexual arousal and desire—supporting enhanced libido, sexual motivation, and intimate wellness through centrally-mediated mechanisms.

Reduced UV Dependence

Achieves tanning effects with less UV exposure compared to traditional tanning methods—potentially lowering cumulative UV damage and skin cancer risk associated with excessive sun exposure.

Long-Lasting Effects

Melanin production continues for days after administration, with tan development occurring gradually and persisting longer than UV-induced tanning—offering sustained cosmetic benefits.

Mechanism of Action

Melanocortin Receptor Activation

Melanotan-2 binds to multiple melanocortin receptor subtypes, triggering diverse physiological responses including melanogenesis, sexual arousal, and metabolic regulation.

1

MC1R Stimulation

Activates melanocortin-1 receptors in melanocytes, stimulating eumelanin production and increasing skin pigmentation—producing darker skin tones with reduced UV exposure requirements.

2

CNS Receptor Activation

Binds to MC3R and MC4R receptors in the brain, enhancing sexual arousal, desire, and motivation through central nervous system pathways—similar to PT-141’s mechanism of action.

3

Photoprotection Effect

Increased melanin provides natural photoprotection against UV radiation damage—potentially reducing sunburn risk and offering ancillary skin protection benefits beyond cosmetic tanning.
