Melanotan II Reconstitution Calculator

Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone studied in pigmentation research. It ships lyophilized and is reconstituted with bacteriostatic water. Research doses are in the small microgram range, so accurate concentration math is critical.

Reading the result: If you have a 5mg vial reconstituted with 2mL of BAC water, your concentration is 2,500 mcg/mL. On a U-100 insulin syringe, that's 25 mcg per IU mark.

Melanotan II concentration reference

Pre-computed concentrations for common Melanotan II vial sizes (10 mg) across 1–3 mL of bacteriostatic water. All values assume a U-100 insulin syringe.

Melanotan II research reference

  • Dosing range: Loading then maintenance; published research uses small mcg-range doses (research range)
  • Administration: Subcutaneous
  • Storage: Refrigerate after reconstitution; used within 30 days in most research protocols.

How the math works

Concentration (mcg/mL) = vial mass (mg) × 1000 ÷ bacteriostatic water volume (mL). For a 10 mg Melanotan II vial reconstituted with 2 mL, that is 5,000 mcg/mL. On a U-100 insulin syringe (100 IU marks per mL), each IU mark holds 50 mcg.
