Calculator for Melanotan II (MT2) reconstitution and per-administration dosing maths. MT2 is supplied in pen, vial, and intranasal-spray formats.

Universal peptide & nootropic dose calculator
Standard research pen format: 3 mL total volume, 300 clicks per pen. That’s fixed โ so the only thing that changes is how many mg are in your specific pen. mg per click = your pen’s mg รท 300.
Vial mode: most research peptide vials are 3 mL borosilicate glass (industry standard โ about 99% of compounds ship in this size). Larger compounds like NAD+ or high-mg GHK-Cu sometimes come in 5โ10 mL vials. The bacteriostatic water you add must fit inside your physical vial โ for a standard 3 mL vial, that’s usually 1โ3 mL of BAC water. Tell us the vial’s peptide content (in mg), the BAC water you added, and your target dose โ we work out the concentration, the volume to draw, and the syringe units on a U-100 insulin syringe.

About Melanotan II (MT2)
Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone (ฮฑ-MSH). It is supplied as a research-grade compound for laboratory study and is unscheduled under the UK Misuse of Drugs Act 1971. However, the MHRA has previously issued public-safety statements about MT2 โ the compound is not licensed as a medicine in the UK and is not approved for human consumption.
Published research literature describes MT2 in pigmentation, appetite, and sexual-function research contexts.
Typical reconstitution / pen formats
| Format | BAC water | Concentration / mg per click | Volume to draw / clicks | For |
|---|---|---|---|---|
| 10mg vial | 2 mL BAC water | 5.0 mg/mL | 0.10 mL (10 units U-100) | for a 500mcg target administration |
| 10mg vial | 5 mL BAC water | 2.0 mg/mL | 0.25 mL (25 units U-100) | for a 500mcg target administration |
Melanotan II (MT2) dosing observed in research literature
Reported research-literature dose ranges for MT2 fall predominantly in the 250mcgโ1mg range per administration, with daily administration during initial loading phases and reduced-frequency maintenance described.
These figures are reported here for completeness of the research-literature picture and do not constitute a dosage recommendation.
Half-life and frequency
Short serum half-life, supporting the daily-loading and reduced-frequency-maintenance pattern described in research literature.
Storage and shelf life
Lyophilised refrigerated; reconstituted with BAC water approximately 28 days refrigerated.
Frequently asked questions
How much bacteriostatic water for a 10mg MT2 vial?
A common choice is 2 mL of BAC water, giving 5 mg/mL โ a 10-unit draw on U-100 for a 500mcg target administration.
Is MT2 legal in the UK?
MT2 is not a controlled substance under the Misuse of Drugs Act 1971 and is supplied as a research-grade compound. However, the MHRA has historically issued public-safety statements about MT2 and the compound is not licensed as a medicine.
How is MT2 typically administered in research?
Subcutaneous administration is the predominant pattern in research literature, with daily loading-phase administration described in published protocols.
