★ How to reconstitute

Reconstituting Melanotan-II, step by step.

  1. 1Draw 2 mL of BAC water into a 3 mL syringe.
  2. 2Tilt the MT-II vial 45° and inject the water gently down the inside wall.
  3. 3Swirl until clear. The powder dissolves fast — no shaking, no heat.
  4. 4Refrigerate. Reconstituted MT-II is good for ~30 days cold.
★ FAQ

Melanotan-II questions, answered.

What's a starter dose of Melanotan-II?+

Most people start at 100–250 mcg (1–2.5 units on a U-100 syringe from a 20 mg / 2 mL mix) for the first few injections to test for nausea and flush. Working dose for tanning is typically 500–1000 mcg per shot, dosed daily until you hit your target tone.

How do I avoid the nausea?+

Inject before bed and eat a small meal first. Lower starting doses help — the nausea is dose-dependent and most people tolerize within a week.

Does MT-II tan you without UV exposure?+

No. MT-II primes melanocytes; UV light from sun or tanning beds is what activates them. Without UV you'll get a mild background tan at best. With brief UV exposure you'll tan deeply and quickly — that's the whole point.
