MT1
MT1 (Melanotan 1 / Afamelanotide) is a synthetic peptide that mimics your body’s natural melanocyte-stimulating hormone (MSH). It’s mainly used for skin pigmentation and UV protection, but it has a few additional effects.
Here’s a clear, complete breakdown:
🌞 Main Benefits of MT1 Injections
☀️ 1. Increased Skin Pigmentation (Tanning)
  • Stimulates melanin production in the skin
  • Helps you tan faster and more evenly
  • Can deepen natural skin tone without as much UV exposure
  • Often used to reduce the need for excessive sunbathing or tanning beds
🛡️ 2. UV Protection Support
  • Higher melanin levels can help: Reduce risk of sunburn Provide some natural defense against UV damage
  • Not a replacement for sunscreen, but adds a layer of protection
🧬 3. May Help With Certain Skin Conditions
MT1 (specifically the prescription form afamelanotide) has been used for:
  • Photosensitivity disorders (like extreme sun intolerance)
  • Some people report improvement in: Uneven pigmentation Vitiligo (in certain cases, when combined with UV therapy)
✨ 4. More Even Skin Tone
  • Can help: Blend uneven pigmentation Reduce appearance of pale patches
  • Results vary depending on your natural skin type
🔥 5. Mild Appetite Suppression (less common vs MT2)
  • Some users notice: Slight decrease in appetite
  • Much weaker effect compared to MT2
⚖️ MT1 vs MT2 (quick context)
  • MT1: More focused on skin + safer profile
  • MT2: Stronger effects but more side effects (nausea, libido changes, etc.)
⚠️ Potential Side Effects
Even though MT1 is considered milder, you can still see:
  • Nausea (usually mild)
  • Flushing or warmth
  • Freckle/mole darkening (monitor skin changes carefully)
  • Fatigue (rare)
  • Headache (occasionally)
🚨 Important Considerations
  • Still requires UV exposure to fully activate tanning effects
  • Overuse or high doses can lead to uneven darkening or excessive pigmentation
  • Long-term safety data is still limited outside of prescription use
  • Always monitor moles/skin changes closely
💡 Best Practices (general)
  • Start low and increase gradually
  • Pair with controlled, short UV exposure
  • Stay consistent rather than taking large doses
