Melanotan-2 (MT-2)
What is Melanotan-2?
Melanotan-2 (MT-2) is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production, leading to increased skin pigmentation (tanning). It is primarily used for sunless tanning, skin protection from UV damage, and libido enhancement.
Originally developed as a treatment for skin cancer prevention, Melanotan-2 has gained popularity for its ability to produce a deep, long-lasting tan without excessive sun exposure. Additionally, it has been noted for its effects on sexual arousal and appetite suppression.
How It Works (Mechanism of Action)
Melanotan-2 works by stimulating melanocortin receptors, which regulate melanin production, energy balance, and sexual function:
-
Increases Melanin Production (Tanning Effect):
- Stimulates melanocytes in the skin, leading to darker pigmentation and a sun-kissed appearance.
-
Protects Against UV Damage:
- Increases natural skin protection by boosting melanin, which acts as a biological sunscreen.
-
Enhances Libido & Sexual Function:
- Stimulates melanocortin receptors in the brain, leading to increased sexual desire and arousal (often used for erectile dysfunction).
-
Appetite Suppression & Fat Loss:
- May reduce food cravings and aid in weight loss by influencing metabolic pathways.
-
Possible Anti-Inflammatory Effects:
- Research suggests it may have anti-inflammatory and neuroprotective properties, though more studies are needed.
Potential Benefits & Use Cases
- Deep, Long-Lasting Tan: Provides a natural-looking tan without excessive sun exposure.
- UV Protection & Skin Cancer Prevention: May help reduce the risk of skin damage and melanoma.
- Libido & Erectile Function Enhancement: Frequently used as a natural alternative for erectile dysfunction (ED) treatment.
- Appetite Suppression & Weight Loss: May contribute to reduced cravings and improved metabolic function.
- Potential Neuroprotective & Anti-Inflammatory Benefits: Early research suggests it may have anti-inflammatory effects.
Typical Dosage & Administration
- Administration: Subcutaneous injection.
- Dosage:
- Loading Phase: 0.25 mg – 0.5 mg per day for the first 1-2 weeks.
- Maintenance Dose: 0.1 mg – 0.3 mg every few days once the desired tan is achieved.
- Effects can take a few days to a couple of weeks to become noticeable.
- Works best when combined with minimal sun exposure to enhance pigmentation.
Possible Side Effects
- Nausea & Flushing: Common in early use but usually subsides over time.
- Increased Skin Pigmentation & Darkened Moles/Freckles: May cause existing moles to darken.
- Erections & Increased Libido: Some users report spontaneous erections and heightened sexual desire.
- Appetite Suppression: Can reduce food intake, which may contribute to weight loss.
- Fatigue or Lightheadedness: Mild symptoms, especially after injection.
Other Relevant Details
- Long-lasting tan: Once developed, the tan can last for weeks, even without sun exposure.
- Not FDA-approved: MT-2 is still under research and is not officially approved for medical use.
- Can be stacked with other peptides for anti-aging and metabolic benefits.
