Melanotan 2 Dosage Calculator: Reconstitution and Units

To calculate Melanotan 2 dosage, divide your target dose (mg) by the vial concentration. For a 10 mg vial with 2 mL BAC water: concentration is 5 mg/mL. A 0.5 mg dose equals 0.1 mL (10 U-100 units). A 1 mg dose equals 0.2 mL (20 U-100 units) on a standard insulin syringe.

Common vial and BAC water combinations with calculated concentration, draw volume, and U-100 syringe units. For education only — verify your vial label before use.

Vial (mg)	BAC water (mL)	Concentration	Dose (mg)	Draw (mL)	U-100 units
10 mg	2 mL	5 mg/mL	0.25 mg	0.05 mL	5 units
10 mg	2 mL	5 mg/mL	0.5 mg	0.1 mL	10 units
10 mg	2 mL	5 mg/mL	1 mg	0.2 mL	20 units
10 mg	2 mL	5 mg/mL	1.5 mg	0.3 mL	30 units

How to Calculate Melanotan 2 Dosage

Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.

Step 1 — Calculate concentration (mg/mL)
Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg Melanotan 2 vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.
Step 2 — Calculate draw volume (mL)
Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.
Step 3 — Convert to U-100 syringe units
Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.

Dosage Formula

Concentration formula

Concentration (mg/mL) = Vial mg ÷ BAC water mL

Draw volume formula

Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)

U-100 syringe units

U-100 units = Draw volume (mL) × 100

These three formulas apply to any Melanotan 2 vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example Melanotan 2 Calculations

Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.

0.5 mg dose from 10 mg / 2 mL vial

Vial: 10 mg | BAC water: 2 mL | Target dose: 0.5 mg
Concentration: 10 ÷ 2 = 5 mg/mL
Draw volume: 0.5 ÷ 5 = 0.1 mL
U-100 units: 0.1 × 100 = 10 units

1 mg dose from 10 mg / 2 mL vial

Vial: 10 mg | BAC water: 2 mL | Target dose: 1 mg
Concentration: 10 ÷ 2 = 5 mg/mL
Draw volume: 1 ÷ 5 = 0.2 mL
U-100 units: 0.2 × 100 = 20 units

Melanotan 2 Reconstitution Guide

Melanotan 2 (MT-2) is a synthetic melanocortin analog typically supplied as lyophilised powder in 10 mg vials. Reconstitute with bacteriostatic water for extended stability.

Swab both vial stoppers with alcohol swabs and allow to air dry.
Draw 2 mL BAC water into a sterile syringe (yields 5 mg/mL).
Inject BAC water slowly along the glass wall — not directly onto the powder.
Gently swirl until fully dissolved. Do not shake.
Store at 2–8 °C and use within 4–6 weeks.

Frequently Asked Questions

What is the standard Melanotan 2 reconstitution?

A common setup is a 10 mg vial + 2 mL BAC water = 5 mg/mL. At this concentration, 0.5 mg = 0.1 mL = 10 U-100 units and 1 mg = 0.2 mL = 20 U-100 units.

How many doses does a 10 mg Melanotan 2 vial provide?

At 5 mg/mL (10 mg + 2 mL BAC water): a 0.5 mg dose gives 20 doses per vial; a 1 mg dose gives 10 doses per vial.

What are U-100 syringe units?

U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading.

Do I need to recalculate if I change the amount of BAC water?

Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration.

What is Melanotan 2 used for in research?

Melanotan 2 is a melanocortin agonist researched for its effects on pigmentation and energy regulation via MC1R and MC4R pathways. It is a research compound only.
