Melanotan II is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Melanotan II is typically reconstituted with bacteriostatic water (BAC water). The standard dosage of 250-500 mcg per injection is administered every other day via subcutaneous injection. Use our peptide calculator for exact mixing ratios.
How Do You Reconstitute Melanotan II?
Melanotan II is supplied as a lyophilized (freeze-dried) powder that must be reconstituted before use. Proper reconstitution is critical for accurate dosing and maintaining stability.
This guide covers the step-by-step process for mixing Melanotan II with bacteriostatic water to achieve your target concentration.
What Supplies Do You Need?
To reconstitute Melanotan II, you need: the Melanotan II vial (lyophilized powder), bacteriostatic water (BAC water with 0.9% benzyl alcohol), insulin syringes (typically 1mL/100-unit), alcohol swabs, and a clean workspace.
Important: Always use bacteriostatic water — not sterile water or saline. BAC water's benzyl alcohol prevents bacterial contamination, extending the usable life of reconstituted Melanotan II to 4-6 weeks.
Step-by-Step Melanotan II Reconstitution
Step 1: Clean the vial tops of both the Melanotan II and BAC water with alcohol swabs.
Step 2: Draw the calculated amount of BAC water into an insulin syringe. Use our peptide calculator to determine the exact amount.
Step 3: Insert the needle into the Melanotan II vial at an angle, and let the water run down the side of the glass — never spray directly onto the powder as this can damage the peptide bonds.
Step 4: Gently swirl (do not shake) the vial until the powder is fully dissolved. The solution should be clear.
Step 5: Label the vial with the date and concentration. Store at 2-8°C.

Open Calculator →How Do You Dose Reconstituted Melanotan II?
After reconstitution, the standard Melanotan II dose is 250-500 mcg per injection administered every other day via subcutaneous injection. The number of units on your insulin syringe depends on how much BAC water you added.
Our calculator will tell you exactly how many units to draw for your dose based on your specific reconstitution ratio.
How Do You Store Reconstituted Melanotan II?
Store reconstituted Melanotan II at 2-8°C (standard refrigerator temperature). Use within 4-6 weeks. Keep away from light and temperature fluctuations.
Unreconstituted Melanotan II powder can be stored at -20°C for 12+ months. Once you reconstitute it, the clock starts.
Bottom Line
Reconstituting Melanotan II is straightforward — add BAC water, swirl gently, refrigerate. The key is using the right amount of water for accurate dosing. Use our peptide calculator every time.

Frequently Asked Questions
What is Melanotan II?
Melanotan II (Melanotan II (cyclic α-MSH analog)) is a Non-selective melanocortin receptor agonist. Synthetic cyclic α-MSH analog with non-selective activity across MC1, MC3, MC4, and MC5 receptors. It is researched for rapid skin darkening, appetite suppression, erectile function enhancement, increased libido.
What is the recommended Melanotan II dosage?
Common dosages: 250-500 mcg per injection administered every other day via subcutaneous injection. Cycle length: 2-4 weeks for tanning effects. Half-life: not precisely established; effects persist longer than MT-I. Use our peptide calculator for exact reconstitution math.
What are the side effects of Melanotan II?
Extensive adverse effects: nausea, vomiting, facial flushing, involuntary erections, yawning, loss of appetite. Serious reports of rhabdomyolysis, renal infarction, posterior reversible encephalopathy syndrome, and sympathomimetic toxicity. Increased melanoma risk, atypical moles, melanonychia (nail darkening). Dose-dependent toxicity.
Is Melanotan II safe?
Melanotan II has shown a preliminary safety profile in research. Not FDA-approved. Banned for human use in many jurisdictions. Warnings issued by US FDA, UK MHRA, and other health agencies. WADA banned. All research should follow appropriate safety protocols.
