About Melanotan II

A non-selective melanocortin receptor agonist studied for melanogenesis (skin tanning), appetite suppression, and sexual arousal.

Research dose ranges

  • Dose: 2501000 mcg per administration
  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~30 hours
  • Cycle: 4 weeks on / 4 off

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.

Storage

Lyophilized vials stable at 2–8°C. Reconstituted solution should be refrigerated and used within 30 days. Protect from light.

Melanotan II calculator FAQ

How do I use the Melanotan II calculator?+

Confirm your vial size in mg (default 10), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Melanotan II reconstitution?+

Most Melanotan II research protocols reconstitute a 10 mg vial with 2 mL of bacteriostatic water, yielding 5000 mcg/mL.

What syringe should I use for Melanotan II?+

U-100 insulin syringes are standard for Melanotan II subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Melanotan II calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
