Melanotan II typical research dosing

Across the available literature, Melanotan II is most commonly administered at 2501000 mcg per dose, 1 time(s) per day, via subcutaneous injection. Research protocols typically use 250–1000 mcg subcutaneously. Most protocols start at 250 mcg to assess tolerance before escalating. MT-II is not used daily continuously; most research cycles are 4–6 weeks. Not for use without UV exposure for melanin production goals — some sun or UV exposure is required for melanin deposition.

Melanotan II unit-conversion table

The number of insulin-syringe units you draw depends on how much bacteriostatic water you used to reconstitute the vial. The table below shows units to draw on a U-100 syringe for a 10 mg Melanotan II vial at common reconstitution volumes.

Melanotan II cycle length

Most reported Melanotan II protocols run 4 weeks on, then 4 weeks off. Cycles are used in research to study washout, receptor sensitivity, and to re-baseline endogenous signaling before re-introducing the compound.

Melanotan II half-life and timing

Melanotan II has a half-life of approximately 30 hours. This influences dose frequency: shorter half-lives often require multiple doses per day to maintain steady-state levels, while longer half-lives can be dosed less frequently.

Melanotan II dosage FAQ

What's the standard Melanotan II dose?+

Research protocols commonly use 250–1000 mcg per administration, 1× per day, via subcutaneous injection. Individual study designs vary.

How long is a typical Melanotan II cycle?+

4 weeks on, 4 weeks off is the most commonly reported research cycle.

How do I convert Melanotan II mcg to insulin syringe units?+

Reconstitute the 10 mg vial with 2 mL bacteriostatic water for 5000 mcg/mL. On a U-100 syringe, 1 unit = 50.0 mcg. Use the calculator on this page to compute exactly.

What time of day should I administer Melanotan II?+

Timing varies by protocol. Some researchers split doses to maintain steady levels; others administer post-workout or pre-bed. Consistent timing improves research-quality observations.

What's the difference between mcg and mg for Melanotan II?+

1 mg = 1,000 mcg (micrograms). Most Melanotan II research doses are in mcg because the bioactive amount is small relative to vial size. A 10 mg vial contains 10000 mcg total.
