Melanotan II dosage

Melanotan II injectable dosage

Reported-use amounts for Melanotan II are 250–500 mcg per administration, daily, for 4–8 wk. A separate reported subcutaneous pattern uses 100–250 mcg daily during a 1–2-week loading period, followed by 50–100 mcg every two or three days. The source does not define a fixed maintenance end date or establish the safety of ongoing use.[9][10]

Melanotan II stimulates melanocortin receptors associated with pigmentation and sexual-response signaling. Pigmentation changes and nausea can occur alongside its intended tanning effect.[1][2][3][9]

Frequency and timing

Evening is the listed injection timing.[4][5][1][9]

Cycle length and breaks

Injectable: 4–8 wk. A standard break interval between courses is not established.[9]

Approval and product quality

Melanotan II is not an FDA-approved drug.[5][6][7][8]

Side effects and long-term safety

Gastrointestinal, vascular, appetite and libido changes can accompany melanocortin activity. Mole and pigmentation changes, long-term melanoma risk, dose-response and repeated-cycle cardiovascular safety remain concerns.[4][1][2][3]

Route-specific dosing limits

Unapproved injectable sourcing and product purity add risks beyond the molecule’s pigmentation and cardiovascular effects. Reported-use injectable schedules and additional protocol patterns are not established human treatment regimens or approved product instructions.[4][1][2][3][10][9]
