What is Melanotan II?
Melanotan II (MT-2) is a synthetic analogue of the naturally occurring peptide hormone alpha-melanocyte-stimulating hormone (α-MSH). It acts on melanocortin receptors and has been studied for its effects on skin pigmentation (tanning), sexual function, and appetite suppression.
Research Dosing Parameters
- Typical dose range: 500 mcg–1 mg per injection
- Common vial size: 10 mg
- Reconstitution: 2–5 mL bacteriostatic water
- Loading phase: Daily injections in initial research protocols; then maintenance
How to Reconstitute Melanotan II
- Inject bacteriostatic water slowly into the lyophilized vial
- Swirl gently until fully dissolved — do not shake
- The solution should be clear and colorless
- Store at 2–8°C after reconstitution
- Use within 30 days; protect from light
FAQ
What is the difference between Melanotan I and Melanotan II? Melanotan I (afamelanotide) is more selective for the MC1 receptor and focused on pigmentation. Melanotan II acts on multiple melanocortin receptors (MC1, MC3, MC4) and has broader studied effects including libido.
How do I calculate Melanotan II units for a 500mcg dose? Enter your vial size (10mg), BAC water volume (e.g. 2mL), and dose (500mcg) in the calculator above to get exact syringe units.
How should I start with Melanotan II in research protocols? Research protocols typically begin at low doses (250mcg or less) and titrate upward to assess response before reaching a standard maintenance dose.
