Melanotan I Dosage Chart
Melanotan I is an alpha-MSH analogue studied for melanogenesis and photoprotection. Its therapeutic cousin, afamelanotide (Scenesse), is approved for erythropoietic protoporphyria. Melanotan I is more selective than Melanotan II and is associated with fewer off-target effects at comparable tanning exposure.

Dosage Protocols
Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.
Protocol 1
Loading Protocol
Dose
0.5mg once daily
Duration
Until desired pigmentation (often 1-3 weeks)
Lower and slower than Melanotan II protocols. Some UV exposure is typically part of the research context to drive melanogenesis. Start at 0.25-0.5mg to assess tolerance.
Protocol 2
Maintenance Protocol
Dose
0.5-1mg, 1-2 times per week
Duration
Ongoing (cycled)
Reduced-frequency dosing to maintain pigmentation after the loading phase.
Protocol 3
Conservative Entry
Dose
0.25mg once daily
Duration
First week
Low starting dose to assess nausea and flushing before stepping up.

Handling Notes
Lyophilized: 2-8°C preferred, -20°C for extended storage. Reconstituted: refrigerate at 2-8°C and use within about 28 days. Protect from light.
Research Considerations
Cautions
- Melanotan I is a research compound not approved for human use; the approved analogue afamelanotide is prescription-only.
- Melanocortin agonists can darken and change moles; baseline and ongoing skin/mole checks are strongly advised.
- Nausea and facial flushing are the most common early effects. Source only COA-verified material.
