How to Use Melanotan 2: Dosing, Tanning Protocol, and Side Effects
Complete Melanotan 2 guide — loading dose (0.25mg), maintenance protocol, UV exposure timing, and managing nausea and spontaneous erections.
Overview
Melanotan 2 (MT-2) is a synthetic melanocortin receptor agonist that stimulates melanin production, producing a tan without UV exposure. It also has sexual arousal effects (similar to PT-141) and appetite suppression. This guide covers the loading protocol and side effect management.
What You Need
- Melanotan 2 vial (10mg)
- Bacteriostatic water (2mL)
- Insulin syringes (U-100)
- Alcohol swabs
- Sunscreen (for UV sessions)
Step-by-Step Instructions
Reconstitute the vial
Add 2mL bacteriostatic water to a 10mg MT-2 vial for 5mg/mL (5000mcg/mL) concentration.
Start with a very low loading dose
Begin at 0.25mg (250mcg) to assess tolerance. At 5000mcg/mL: 250mcg = 0.05mL = 5 units on a U-100 syringe.
Gradually increase to loading dose
Over 1–2 weeks, increase to 0.5–1mg per day. Inject daily during the loading phase until desired tan depth is achieved (typically 2–4 weeks).
Transition to maintenance dosing
Once desired tan is achieved, reduce to 0.5–1mg twice per week to maintain color. UV exposure 1–2x per week helps maintain the tan.
Manage side effects
Nausea: inject at night, start low, use anti-nausea medication. Spontaneous erections (men): reduce dose or switch to morning injection. Facial flushing: transient, dose-dependent. Mole darkening: monitor existing moles — consult a dermatologist if any change.
Common Mistakes to Avoid
Starting at 0.5–1mg
Fix: Always start at 0.25mg. The nausea and flushing at higher initial doses can be severe and leads to discontinuation.
Not using UV exposure
Fix: MT-2 stimulates melanin production, but UV light is needed to activate and distribute the melanin. Without UV, results are minimal.
Ignoring mole changes
Fix: MT-2 stimulates melanocytes broadly. Monitor all existing moles and see a dermatologist if any change. Do not use MT-2 if you have a history of melanoma.
Frequently Asked Questions
Is Melanotan 2 safe?
MT-2 is not FDA-approved and carries risks including mole darkening, nausea, and spontaneous erections. The long-term safety profile is unknown. It should not be used by anyone with a personal or family history of melanoma.
How long does the Melanotan 2 tan last?
With maintenance dosing (0.5–1mg twice weekly) and periodic UV exposure, the tan can be maintained indefinitely. Without maintenance, the tan fades over 4–8 weeks.
Does Melanotan 2 work without UV exposure?
MT-2 produces some baseline melanin stimulation without UV, but UV exposure significantly amplifies and distributes the melanin. Most users use both together for best results.
