Melanotan II by XT Labs is a synthetic analog of the alpha-melanocyte-stimulating hormone (1$alpha$-MSH).2 This peptide is primarily used for its ability to induce skin pigmentation (tanning) by stimulating melanocytes to produce melanin.3 Unlike the larger 10 mg vials often found on the market, this 2 mg vial is ideal for beginners or those who prefer "fresh" reconstitution to minimize the degradation of the peptide over time.
This USA Domestic kit includes the 2 mg lyophilized vial and a dedicated vial of Bacteriostatic Water, ensuring rapid delivery and all necessary components for use.
Efficient Tanning: Stimulates a deep, natural tan with significantly less UV exposure required, reducing the risk of skin damage from over-tanning.
Appetite Suppression: Interacts with the MC4R receptors in the brain to help curb hunger, making it a useful tool during "cutting" or fat-loss phases in bodybuilding.4
Increased Libido: Known for its potent "pro-erectile" effects and overall boost in sexual desire.5
Photoprotection: Increases the skin's natural melanin levels, providing a biological barrier against future UV rays.

For a 2 mg vial, precise dosing is critical to avoid side effects. Subcutaneous injection is the standard method.
Reconstitution: Inject 1 ml or 2 ml of Bacteriostatic Water into the vial.
Conservative Protocol (2 ml dilution):
Assessment Dose: 100 mcg (10 units on a 100-unit syringe).
Standard Dose: 250 mcg (25 units on a 100-unit syringe).
Timing: Administering before bed is highly recommended to sleep through potential nausea or flushing.
UV Interaction: While it can tan without UV, a very small amount of sunlight (10-15 mins) every few days acts as a catalyst to "lock in" the color.
Nausea: Most common with the first few doses. Start with a very low dose to build tolerance.
Facial Flushing: A temporary feeling of warmth and redness shortly after injection.
Mole Darkening: Existing moles or freckles may become darker. Discontinue use if you notice irregular changes.
Blood Pressure: May cause a temporary slight increase in blood pressure; monitor if you have pre-existing hypertension.6
Pre-mixing: Store in a cool, dark place.
Post-mixing: Must be kept refrigerated. Because this is a 2 mg vial, it is typically used up within 1–2 weeks, ensuring the peptide remains highly potent throughout use.
Handling: Gently swirl to mix. Never shake, as it can damage the peptide structure.
