MT-1 (Melanotan I) is a synthetic analog of melanocyte-stimulating hormone (α-MSH) and belongs to the class of melanocortin receptor agonists. It primarily functions by binding to the melanocortin-1 receptor (MC1R) within the body, thereby stimulating the production of melanin and inducing natural skin tanning upon exposure to ultraviolet light; it was originally developed primarily for the treatment of photosensitivity disorders or for use in related dermatological research.

In the biomedical and consumer markets, it primarily has the following applications and relevant background:

1. **Core Function and Applications—Induced Tanning and Photoprotection:** It stimulates the skin to produce melanin by binding to the Melanocortin 1 Receptor (MC1R) located on cutaneous melanocytes. Clinically (e.g., under the brand name Scenesse), it is approved for the treatment of photosensitivity disorders—such as Erythropoietic Protoporphyria (EPP)—where it significantly reduces the phototoxicity and photosensitivity reactions experienced by patients upon exposure to ultraviolet (UV) light.

**Misuse by "Biohackers":** In recent years, this peptide has sparked a craze within fitness and beauty circles, where it is utilized as a melanogenic agent by individuals seeking to achieve a healthy, bronzed complexion. Users typically administer the substance via subcutaneous  into the fatty tissue layer to accelerate and enhance skin darkening following sun exposure.

2. Differences from MT-2 (Melanotan II): MT-1 is frequently discussed alongside MT-2. MT-1 primarily specializes in melanogenesis  and rarely exhibits other hormone-like activities. MT-2 exerts a broader effect on receptors; in addition to inducing pigmentation, it often demonstrates effects such as appetite suppression and modulation of libido (e.g., improving erectile dysfunction).
