Melanotan II Quick Reference

Typical Dose

250 mcg - 1 mg

Frequency

1x daily (loading), then maintenance

Route

Subcutaneous injection

Half-Life

~1 hour

Common Vials

10 mg

Reconstituted Stability

Up to 30 days refrigerated

Note: Start with a low dose (0.25 mg) to assess tolerance due to common initial nausea. Loading phase typically lasts 2-3 weeks with daily injections. Maintenance doses are less frequent. UV exposure is still needed for tanning effect.

Melanotan II Storage

Lyophilized: room temp or 2-8 C. Reconstituted: 2-8 C

Stability after reconstitution: Up to 30 days refrigerated. Always use bacteriostatic water for multi-use reconstitution. Label the vial with the reconstitution date and discard after the stability period. Use our peptide calculator above to determine the right amount of water to add.

Melanotan II Frequently Asked Questions

Start at 0.25 mg daily for 2-3 days to assess tolerance, then increase to 0.5-1 mg daily. Loading phase typically lasts 2-3 weeks until desired skin tone is achieved.

Add 2 mL bacteriostatic water for 5 mg/mL. For 0.25 mg, draw 0.05 mL (5 units). For 0.5 mg, draw 0.1 mL (10 units). For 1 mg, draw 0.2 mL (20 units).

Yes. Melanotan II stimulates melanin production but UV exposure is still needed to activate the tanning process. Use moderate sun or sunbed exposure during the loading phase.

After achieving desired tan, reduce to 0.25-0.5 mg once or twice per week to maintain skin tone. Some users only dose before anticipated sun exposure.

Nausea is very common, especially in the first few days. It typically subsides as tolerance builds. Injecting before bed can help avoid the discomfort. Starting at a lower dose (0.25 mg) minimizes nausea.

Visible tanning effects typically appear within 5-7 days of daily use with UV exposure. Full effect usually develops over 2-3 weeks of consistent loading.
