Tanning Protocol with Melanotan-II
⚠️ Critical Safety Information
Research Use Only: Melanotan-II is NOT FDA-approved for any use. This peptide carries significant risks including potential links to melanoma development, cardiovascular effects, and unknown long-term consequences. This information is for educational purposes only. Consult healthcare providers and dermatologists before considering use.
Melanotan-II (MT-II) is a synthetic analog of alpha-melanocyte stimulating hormone (α-MSH) that stimulates melanogenesis (melanin production) in the skin. It produces a tan without requiring UV exposure, though UV exposure accelerates and deepens the tanning effect. MT-II is popular among fair-skinned individuals who burn easily and those seeking year-round tans.
How Melanotan-II Works
Mechanism of Action
MT-II activates melanocortin receptors (primarily MC1R) in melanocytes, triggering:
- Increased melanin synthesis: Stimulates production of eumelanin (brown-black pigment)
- Melanocyte proliferation: Increases number of pigment-producing cells
- Melanosome distribution: Spreads melanin throughout skin layers
- Enhanced UV response: Amplifies natural tanning response to sun exposure
Tanning Timeline
- Days 1-3: No visible changes, peptide accumulating
- Days 4-7: Slight darkening, freckles may appear first
- Days 7-14: Noticeable tan development, especially with UV exposure
- Days 14-21: Full tan achieved, maintenance phase begins
- Maintenance: Tan persists 2-4 weeks after stopping, fades gradually
Skin Type Considerations
Best Results (Type I-III):
- Type I (Always burns, never tans): Most dramatic results, requires lowest doses
- Type II (Usually burns, tans minimally): Excellent results, standard dosing
- Type III (Sometimes burns, tans gradually): Good results, may need higher doses
Limited Results (Type IV-VI):
- Type IV-VI (Rarely/never burns, tans easily): Already have high melanin, minimal additional darkening

Phase 2: During Vacation
- Dose: 0.25-0.5 mg every 2-3 days
- UV Exposure: Natural sun exposure (still use SPF 30+)
- Benefit: Enhanced tanning, reduced burn risk
Phase 3: Post-Vacation Maintenance
- Dose: 0.25-0.5 mg, 2x per week
- Duration: 4-8 weeks to maintain vacation tan
Expected Results: Deep, even tan that lasts weeks beyond vacation. Significantly reduced sunburn risk.
Cost: $50-80 for full protocol
Protocol 4: Year-Round Maintenance
Best for: Maintaining consistent tan without seasonal variation
Initial Loading (First Month)
- Weeks 1-2: 0.5-1 mg daily with UV exposure
- Weeks 3-4: 0.5 mg, 3x per week
Long-Term Maintenance
- Dose: 0.25-0.5 mg
- Frequency: 2x per week (Monday/Thursday or Tuesday/Friday)
- UV Exposure: Optional 10 min weekly, or tanning bed 1x per week
- Cycling: Consider 1 week off every 8-12 weeks
Expected Results: Consistent, year-round tan. Minimal UV exposure needed after initial loading.
Cost: $40-60/month long-term
Administration Guidelines
Reconstitution
- Vial Size: Typically 10mg MT-II powder
- Bacteriostatic Water: Add 2ml for 5mg/ml concentration
- Mixing: Inject water slowly down side of vial, swirl gently (don't shake)
- Storage: Refrigerate immediately, use within 30 days
- Calculation: 5mg/ml = 5000 mcg/ml, so 0.1ml = 500 mcg
Injection Technique
- Site: Subcutaneous in abdomen (pinch skin, inject at 45° angle)
- Needle: Insulin syringe (29-31 gauge, 0.5-1ml)
- Rotation: Rotate injection sites to prevent irritation
- Timing: Evening preferred (reduces nausea, allows overnight melanin production)
- UV Timing: 2-4 hours after injection for optimal melanin response
UV Exposure Guidelines
- Natural Sun: 10-20 minutes during loading, 10 minutes during maintenance
- Tanning Bed: 5-10 minutes, low-intensity beds preferred
- Timing: 2-4 hours post-injection for maximum effect
- Protection: Still use SPF 30+ on face, avoid burns
- Note: MT-II produces some tan without UV, but UV accelerates and deepens color
Side Effects and Management
Common Side Effects (50-80% of users)
- Nausea: Most common, peaks 1-2 hours post-injection
- Management: Dose in evening, take with small meal, reduce dose by 50%
- Usually resolves after 3-7 days of use
- Facial Flushing: Temporary redness, lasts 10-30 minutes
- Management: Normal response, no action needed
- Increased Libido/Spontaneous Erections: Due to MC4R activation
- Management: Expected effect, dose in evening if problematic
- Appetite Suppression: Mild to moderate
- Management: Ensure adequate nutrition, may be beneficial for some
- Darkening of Existing Moles/Freckles: Very common
- Management: Monitor all skin changes, photograph moles before starting
Serious Concerns
- New Mole Formation: MT-II may stimulate new mole growth
- Action: Dermatology screening before and during use
- Monitor for asymmetry, irregular borders, color changes
- Melanoma Risk: Theoretical concern, no long-term safety data
- Action: Regular skin checks, avoid if family history of melanoma
- Cardiovascular Effects: Increased heart rate, blood pressure changes
- Action: Avoid if cardiovascular disease, monitor BP

Optimizing Results
Maximizing Tan Development
- Hydration: Drink 3+ liters water daily (improves skin appearance)
- Exfoliation: Gentle exfoliation 2x per week (removes dead skin, evens tan)
- Moisturization: Daily moisturizer with hyaluronic acid
- UV Timing: 2-4 hours post-injection for peak melanin response
- Consistency: Regular dosing schedule maintains even color
Supplements to Consider
- Astaxanthin: 12mg daily (antioxidant, may enhance tan, UV protection)
- Beta-Carotene: 25,000 IU daily (adds golden undertone)
- Vitamin E: 400 IU daily (skin health, UV protection)
- Vitamin C: 1000mg daily (collagen synthesis, antioxidant)
Avoiding Uneven Tanning
- Exfoliate before starting protocol
- Ensure even UV exposure (rotate body positions)
- Moisturize dry areas (elbows, knees) more frequently
- Avoid tight clothing immediately after UV exposure
Troubleshooting
Not Tanning Fast Enough?
- Increase dose by 0.25 mg (250 mcg)
- Ensure adequate UV exposure (15-20 min daily during loading)
- Verify peptide quality (should be >98% purity)
- Check skin type - Type IV+ may see minimal results
- Allow full 14 days before assessing results
Severe Nausea?
- Reduce dose by 50% for 3-5 days
- Dose in evening with small meal
- Consider anti-nausea medication (ginger, Dramamine)
- Split dose (morning and evening) if tolerated
- Nausea typically resolves after first week
Uneven Tan or Splotchy Appearance?
- Exfoliate thoroughly and consistently
- Ensure even UV exposure
- Moisturize dry areas more frequently
- May take 2-3 weeks to even out
Tan Fading Too Quickly?
- Increase maintenance frequency to 3x per week
- Add weekly UV exposure (10 minutes)
- Ensure adequate hydration and moisturization
- Avoid excessive exfoliation
Discontinuation and Tan Fade
When stopping MT-II:
- Week 1-2: Tan remains at full intensity
- Week 3-4: Gradual fading begins
- Week 5-8: Tan fades to 50% of peak
- Week 8-12: Return to baseline skin tone
Extending Tan: Occasional maintenance doses (0.25-0.5 mg weekly) can extend tan for months.
