What Melanotan I is

Melanotan I, also known as Afamelanotide, is a synthetic analog of alpha-Melanocyte Stimulating Hormone (alpha-MSH), a naturally occurring peptide in the body. It primarily acts as an agonist for the melanocortin 1 receptor (MC1R), which is predominantly found on melanocytes, the cells responsible for producing pigment. By binding to and activating MC1R, Melanotan I stimulates the process of melanogenesis, leading to increased production of melanin, the pigment that determines skin, hair, and eye color. This peptide is designed for sustained action compared to native alpha-MSH, allowing for a more prolonged stimulation of melanin production.

In practical research settings, Melanotan I is observed to induce a gradual tanning effect, typically developing over several weeks of consistent administration. Its slower and milder action, compared to other melanocortin peptides, often results in fewer reported side effects. Researchers typically investigate cycles lasting several weeks to months to achieve the desired level of pigmentation, followed by a potential maintenance phase. It is important to note that Melanotan I is an investigational research compound and is not approved for human medical use, and thus should not be considered for personal use or as a therapeutic agent.

Storage & handling

LYOPHILIZED (unopened): store at 2-8°C (fridge) or -20°C (freezer) long-term. Protect from light.

AFTER RECONSTITUTION: refrigerate 2-8°C. Do NOT freeze. Discard after 30 days OR if the solution becomes cloudy, discolored, or contains particulates.

What people track

Because individual responses vary so much, the useful thing is your own record: what you logged and when, how much is left in the vial, and how your chosen metrics move over the weeks. Peptide Wizard keeps all of that in one place, alongside a 3D reference vial for Melanotan I.
