Melanotan II dosing reference

Melanotan II (also marketed as MT-II®) is a peptide in the Cosmetic category. It is a research peptide and is not FDA-approved for human use. The dose ranges shown (0.25–1 mg) are summarized from peer-reviewed research literature where evidence is preliminary.

Melanotan II most commonly ships in 10 mg vials. Typical reconstitution volumes are 1, 2 ml of bacteriostatic water — choose the volume to land on a syringe-friendly unit count for your target dose.

Use the formula concentration = vial mg ÷ BAC water ml, then volume = dose mg ÷ concentration, then units = volume × 100 (for U-100). For example, a 10 mg vial reconstituted with 1 ml gives 10.00 mg/ml — at the typical low dose of 0.25 mg that resolves to 2.5 units. The free reconstitution calculator on this site verifies the math against your specific vial.

No. Melanotan II is a research peptide and is not FDA-approved for human use in the United States as of April 2026. Any use must come through a licensed healthcare provider, typically via a compounding pharmacy.

Side-effect profiles for research peptides are characterized in published research rather than an FDA label. Most users report mild local reactions at the injection site, occasional fatigue, and headache in the first few doses. Long-term human safety data is limited for most research compounds. Discuss with your prescribing provider before starting.

No. The values shown are reference numbers summarized from authoritative sources — FDA-approved labels for approved compounds and peer-reviewed research for the rest. They are not personalized recommendations. Always follow your prescribing provider's instructions and verify every calculation against your vial label.
