tan couple

Melanotan II (MT2) is a Melanocyte Stimulating Hormone (MSH) which induces pigment cells (melanocytes) in the skin  to produce and release melanin which leads to skin tanning. Patients using MT2 for tanning also report increased fat burning and increased libido. Male patients report enhanced erections too. Due to the sexual "side effects," researchers altered its chemical structure to minimize the tanning and increase the sexual benefits and developed PT-141.

Scientists discovered the use of this “tanning peptide” when investigating possible ways to treat skin cancer. They hypothesized that by inducing the body’s natural pigmentary system through the process of melanogenesis, a protective tan could be produced before UV exposure, thereby reducing the potential for skin damage. With just a little UV exposure, the release of Melanocyte Stimulating Hormone stimulates a natural increase in the production of melanin from the melanocytes in the skin. Use of the tanning peptide provides more MSH which results in more melanin being produced and greater tanning potential (skin pigmentation) regardless of your skin type


  • Deep and natural appearing tan

  • The ability to achieve a darker tan with less exposure to UV radiation

  • Possible reduction in the risk of Melanoma (skin cancer)

  • A possible reduction in the incidence of sun-damaged skin

  • Fair skin individuals have the ability to develop a tan without burning

  • No sunburn

  • No tan lines

  • Increased fat burning

  • Enhanced libido

  • Enhanced erections


Side effects can include:

  • Facial flushing

  • Reduced appetite, nausea and vomiting

  • In males, spontaneous erections 1-5 hours after administration

  • Melanoma – a potentially serious form of skin cancer

  • Deepening of the color of moles, new moles and atypical melanocytic nevi

  • Darkening of freckles

  • Melanonychia – brown to black discoloration of one or more nails

Suggested usage: daily for 1 - 2 weeks then  weekly for maintenance as needed.
