What to Expect on Melanotan II: Week by Week Timeline

The first few days of the loading phase are focused on building peptide levels in the system. Facial flushing, mild nausea, and decreased appetite are commonly reported during initial dosing. Some individuals notice a subtle darkening of moles and freckles as the earliest visible sign of melanocyte activation.

By the end of the first week, many users report the beginning of a visible tan, even with minimal UV exposure. The pigmentation typically appears first on the face, arms, and areas with higher melanocyte density. Appetite suppression and occasional increases in libido are commonly described secondary effects during the loading phase.

The tan continues to deepen and spread across the body during weeks two and three. Many users transition from the loading dose to a maintenance dose around this time. UV exposure, even modest amounts, has been associated with significantly amplifying the pigmentation response during this phase.

Most users reach their desired level of tanning within four to six weeks. The maintenance dose is commonly reduced to the minimum effective amount, often only one to two administrations per week. Skin pigmentation at this stage is typically described as natural-looking and even, with greater UV protection compared to baseline.

After the desired tan is achieved, periodic maintenance doses are used to sustain the pigmentation. Frequency varies from once weekly to once every two weeks depending on individual melanocyte activity and UV exposure. Many people find that their maintenance needs decrease over time as the melanocytes remain primed from the initial loading course.
