Quick answer · Community-reported standard
A 2 mg vial of Melanotan-1 reconstituted with 2 mL of bacteriostatic water yields a concentration of 1.00 mg/mL. At that concentration, a 500 mcg dose of Melanotan-1 equals 50 units on a U-100 insulin syringe (0.500 mL). Melanotan-1 is typically administered once daily via subcutaneous.
Melanotan-1 2 mg reconstitution and dosage: 1 mL vs 2 mL bac water
For a 2 mg vial of Melanotan-1, bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 2 mg vial.
| BAC water added | Concentration | Volume per 500 mcg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 2.00 mg/mL | 0.250 mL | 25 units |
| 2 mL | 1.00 mg/mL | 0.500 mL | 50 units |
Melanotan-1 dosage chart: per-injection to weekly total
Common Melanotan-1 protocol doses centered on the 500 mcg baseline (research range 0.5 mg–1 mg), with weekly totals at once daily frequency.
| Dose level | Per injection | Frequency | Weekly total |
|---|---|---|---|
| Lower | 0.25 mg | Once daily | 1.75 mg |
| Baseline | 0.5 mg | Once daily | 3.5 mg |
| Higher | 0.75 mg | Once daily | 5.25 mg |
| Upper range | 1 mg | Once daily | 7 mg |
Weekly totals assume consistent once daily dosing. Adjust the calculator below for your specific vial size and dose.

Melanotan-1 reconstitution & storage
Lyophilized powder reconstituted with sterile water or bacteriostatic water; peptide is most stable at acidic to neutral pH (avoid pH >8)
Lyophilized powder stored at 2-8C; reconstituted solution refrigerated and used within days; Ea ~15.8 kcal/mol supports significant stabilization with refrigeration
Melanotan-1 dosing FAQ
How much bacteriostatic water should I add to a 2 mg vial of Melanotan-1?
The community standard is 2 mL of bacteriostatic water for a 2 mg Melanotan-1 vial. That gives a concentration of 1.00 mg/mL, so a 500 mcg dose is 50 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 2.00 mg/mL and halves the draw to 25 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 500 mcg dose of Melanotan-1?
On a standard U-100 insulin syringe, a 500 mcg dose of Melanotan-1 is 50 units when the 2 mg vial is reconstituted with 2 mL of bacteriostatic water (1.00 mg/mL). If you use 1 mL of bac water instead, draw 25 units (2.00 mg/mL).
What is the standard Melanotan-1 dose?
Community-reported protocols for Melanotan-1 typically use 0.5 mg–1 mg once daily via Subcutaneous. 500 mcg is a common starting dose. Higher doses than MT-2 due to MC1R selectivity (less potent per mg); combined with moderate UV exposure
How long does a vial of Melanotan-1 last at 500 mcg once daily?
A 2 mg vial of Melanotan-1 contains roughly 4 doses at 500 mcg per injection. At once daily dosing, that is approximately 4 days (about 1 weeks) of supply per vial. Reconstituted Melanotan-1 should generally be used within 28 days when refrigerated.
Where do you inject Melanotan-1?
Melanotan-1 is typically injected subcutaneous. Common sites reported in the literature and by users include: Abdomen (subcutaneous), Upper arm (subcutaneous). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for Melanotan-1?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Melanotan-1 because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
