How to Reconstitute Melanotan II
Melanotan II typically comes in 10 mg vials. Reconstitution is standard but the larger vial size and dose range (0.25-1.0 mg) require attention to concentration calculations for accurate dosing across loading and maintenance phases.
Key Points
Step-by-Step Guide
Select Water Volume
For a 10 mg vial: add 2 mL BAC water = 5 mg/mL. A 0.5 mg dose = 0.1 mL (10 units). This is the most common concentration for convenient dosing.
Reconstitute
Standard technique: alcohol swab both vials, inject BAC water against glass wall, swirl gently. MT-2 dissolves readily into a clear solution.
Protect from Light
Melanotan II is light-sensitive. Store in the original box or wrap the vial in aluminum foil. Keep in the back of the refrigerator away from light exposure.
Calculate Doses
Test dose: 0.05 mL (5 units) = 0.25 mg. Loading dose: 0.1-0.2 mL (10-20 units) = 0.5-1.0 mg. Maintenance: 0.1 mL (10 units) = 0.5 mg.
Store Properly
Refrigerate at 2-8°C protected from light. A 10 mg vial at 0.5 mg/dose provides 20 doses, lasting through the loading phase. Use within 4 weeks.
Warnings & Precautions
- !MT-2 is light-sensitive—store in foil or dark container.
- !Start with a low test dose (0.25 mg) regardless of concentration.
- !A 10 mg vial contains many doses—sterile technique is critical for repeated use.
- !Do not confuse Melanotan I and Melanotan II—different peptides.
Frequently Asked Questions
Why is light protection important for MT-2?
Melanotan II contains amino acids susceptible to photo-oxidation. Light exposure degrades the peptide, reducing potency. Wrapping the vial in foil and refrigerating in a dark location preserves activity.
How long does a 10 mg vial last?
During loading (0.5 mg daily): about 20 days. During maintenance (0.5 mg twice weekly): about 10 weeks. One vial covers the entire loading phase for most protocols.
Can I use sterile water instead of BAC water?
Only if you will use the entire vial within 24-48 hours. For multi-dose use over weeks, bacteriostatic water is essential to prevent bacterial growth.
