What is Melanotan 1?
Melanotan 1 (MT1): A synthetic peptide analog of alpha-melanocyte stimulating hormone (alpha-MSH) that binds to melanocortin 1 receptors (MC1R) to stimulate melanin production in the skin.
Melanotan 1, also known by its pharmaceutical name afamelanotide, was originally developed for research into skin pigmentation disorders. Unlike its cousin Melanotan 2, MT1 is more selective for the MC1R receptor, which may result in fewer off-target effects according to research literature.
The peptide works by triggering melanocytes to produce and distribute melanin throughout the skin. This process can result in gradual skin darkening even without significant UV exposure, though research suggests that some sun exposure may enhance results.
MT1 is typically supplied as a lyophilized (freeze-dried) powder in 10mg vials that must be reconstituted with bacteriostatic water before subcutaneous injection.
Melanotan 1 Dosage Chart: Quick Reference
Based on clinical research protocols and established dosing guidelines, here’s the standard Melanotan 1 dosage breakdown:
| Phase | Duration | Daily Dose | Frequency | Notes |
|---|---|---|---|---|
| Loading Phase (Conservative) | Days 1-10 | 0.25-0.5mg | Once daily | Start low to assess tolerance |
| Loading Phase (Standard) | Days 1-10 | 1mg | Once daily | Per clinical protocols |
| Maintenance Phase | Week 2+ | 0.5-2mg | 1-2x weekly | Adjust based on results |
| Long-term Maintenance | Month 2+ | 1mg | Once weekly | Or as needed to maintain |
Pro Tip: Many experienced users report that starting with 0.25mg and gradually increasing over the first week helps minimize common side effects like nausea and facial flushing.
How to Calculate Your Melanotan 1 Dose?
Calculating your injection volume requires knowing three key variables: your peptide amount, your bacteriostatic water volume, and your target dose.
The Dosage Calculation Formula
Here’s the formula I use for every peptide calculation:
Injection Volume (ml) = Target Dose (mg) / Concentration (mg/ml)
Where concentration = Peptide Amount (mg) / Water Volume (ml)
Step-by-Step Calculation Example
- Determine your peptide amount: Most MT1 vials contain 10mg of lyophilized powder
- Choose your bacteriostatic water volume: The standard is 2ml, creating a 5mg/ml concentration
- Calculate your concentration: 10mg / 2ml = 5mg/ml (or 5000mcg/ml)
- Identify your target dose: For a 0.5mg (500mcg) loading dose
- Calculate injection volume: 0.5mg / 5mg/ml = 0.1ml
- Convert to syringe units: 0.1ml = 10 units on a standard insulin syringe
Quick Dose Reference Table
Using the standard 10mg vial + 2ml bacteriostatic water setup (5mg/ml concentration):
| Target Dose | Injection Volume | Insulin Syringe Units |
|---|---|---|
| 0.25mg (250mcg) | 0.05ml | 5 units |
| 0.5mg (500mcg) | 0.1ml | 10 units |
| 0.75mg (750mcg) | 0.15ml | 15 units |
| 1mg (1000mcg) | 0.2ml | 20 units |
| 1.5mg (1500mcg) | 0.3ml | 30 units |
| 2mg (2000mcg) | 0.4ml | 40 units |
Dosing by Skin Type (Fitzpatrick Scale)
Your Fitzpatrick skin type significantly impacts how your body may respond to Melanotan 1. Research suggests that individuals with lighter skin types may require different protocols than those with naturally darker complexions.
| Skin Type | Description | Recommended Loading Dose | Loading Duration | Maintenance |
|---|---|---|---|---|
| Type I | Very fair, always burns, never tans | 0.25mg daily | 14-21 days | 0.5-1mg 2x weekly |
| Type II | Fair, usually burns, tans minimally | 0.25-0.5mg daily | 10-14 days | 0.5-1mg 2x weekly |
| Type III | Medium, sometimes burns, tans gradually | 0.5mg daily | 7-10 days | 0.5-1mg weekly |
| Type IV | Olive, rarely burns, tans easily | 0.5-1mg daily | 7 days | 1mg weekly |
| Type V-VI | Dark, never burns, tans profusely | 0.5-1mg daily | 5-7 days | 1mg every 1-2 weeks |
Important: These are general guidelines based on available research. Individual responses vary significantly. Always start with the lowest recommended dose for your skin type and adjust based on your personal response.
How to Reconstitute Melanotan 1: Step-by-Step Guide?
Proper reconstitution is critical for peptide stability and accurate dosing. Follow these steps carefully to ensure you’re working with a properly prepared solution.
Supplies Needed
- Melanotan 1 vial: 10mg lyophilized powder
- Bacteriostatic water: 2ml (or your preferred volume)
- Insulin syringes: 29-31 gauge, 0.5ml or 1ml
- Alcohol swabs: For sterilization
Reconstitution Steps
- Prepare your workspace: Clean your work surface and wash your hands thoroughly
- Sterilize the vial tops: Wipe both the peptide vial and bacteriostatic water vial with alcohol swabs
- Draw bacteriostatic water: Using a clean insulin syringe, draw exactly 2ml of bacteriostatic water
- Add water slowly: Insert the needle into the MT1 vial and release water slowly against the glass wall, not directly onto the powder
- Allow to dissolve: Let the vial sit for 5-10 minutes without shaking. Gentle swirling is acceptable if powder remains
- Inspect the solution: The reconstituted peptide should be clear and colorless. Any cloudiness or particles may indicate contamination
- Label and store: Write the reconstitution date and concentration on the vial. Store immediately in the refrigerator
Never shake the vial. Peptides are fragile molecules that can denature with aggressive handling. Always use gentle swirling motions if needed.
Visual Syringe Volume Guide
Understanding syringe markings is essential for accurate dosing. Here’s how common doses translate to syringe units using the standard 5mg/ml concentration.
| Dose | Volume (ml) | Units (U-100 syringe) | Visual Reference |
|---|---|---|---|
| 0.1mg (100mcg) | 0.02ml | 2 units | Barely visible – first small line |
| 0.25mg (250mcg) | 0.05ml | 5 units | Halfway to the 10-unit mark |
| 0.5mg (500mcg) | 0.1ml | 10 units | First major line after 0 |
| 1mg (1000mcg) | 0.2ml | 20 units | Second major line |
| 2mg (2000mcg) | 0.4ml | 40 units | Near middle of 0.5ml syringe |
Pro Tip: On a standard U-100 insulin syringe, each small line equals 1 unit (0.01ml). Each major numbered line represents 10 units (0.1ml). For doses under 5 units, consider using a U-40 syringe for greater precision.
Melanotan 1 vs Melanotan 2: Key Differences
Understanding the differences between MT1 and MT2 helps you make an informed decision about which peptide may be more appropriate for your research goals.
| Feature | Melanotan 1 (MT1) | Melanotan 2 (MT2) |
|---|---|---|
| Pharmaceutical Name | Afamelanotide | No approved name |
| Receptor Selectivity | More selective for MC1R | Binds multiple melanocortin receptors |
| Tanning Effect | Gradual, more natural-looking | Faster, more pronounced |
| Common Side Effects | Nausea, flushing (typically milder) | Nausea, flushing, spontaneous erections |
| Off-Target Effects | Fewer reported | More common (libido, appetite) |
| Typical Loading Dose | 0.5-1mg daily | 0.25-0.5mg daily |
| Research Status | More clinical trials completed | Less formal research |
| Typical Price (10mg) | $35-55 | $25-45 |
MT1 may be preferred by researchers interested in a more targeted approach with potentially fewer side effects, while MT2 is often chosen by those seeking faster results despite the broader receptor activity.
Storage and Stability Guide
Proper storage significantly impacts peptide potency and longevity. Here’s what research suggests about maintaining Melanotan 1 stability.
Storage Requirements
- Unreconstituted (powder): Refrigerate at 2-8C (35-46F) for up to 24 months. Can be frozen for longer storage.
- Reconstituted (liquid): Refrigerate at 2-8C and use within 3-4 weeks for optimal potency.
- Never freeze reconstituted peptide: Ice crystal formation can damage the molecular structure.
- Protect from light: Store in original vial or wrap in foil to prevent light degradation.
Signs of Peptide Degradation
- Cloudy or hazy appearance (should be crystal clear)
- Visible particles or floaters in solution
- Color change (should remain colorless)
- Unusual odor
- Reduced effectiveness despite proper dosing
If you notice any of these signs, the peptide may have degraded and should be replaced.
Potential Side Effects and Safety Considerations
Melanotan 1 research has documented various potential side effects. Based on available literature, here’s what researchers have reported:
Common Side Effects (Mild)
- Facial flushing: Temporary redness, typically lasting 1-2 hours
- Nausea: Most common in first few days, often subsides with continued use
- Headache: Usually mild and temporary
- Injection site reactions: Minor redness or irritation
Less Common Side Effects
- Fatigue or drowsiness: Some users report lethargy
- Appetite changes: Either increased or decreased
- Mole darkening: Existing moles may become more pronounced
Safety Considerations
Important Safety Note: Anyone with a history of skin cancer, dysplastic nevi (atypical moles), or melanoma should not use Melanotan peptides. Consult with a healthcare provider before beginning any peptide research.

Frequently Asked Questions
How much Melanotan 1 should I take?
The standard Melanotan 1 loading dose is 0.25-1mg daily for 7-10 days, followed by a maintenance dose of 0.5-2mg weekly. Most researchers start with 0.25mg to assess tolerance before increasing to the full loading dose.
How do I reconstitute Melanotan 1?
Add 2ml of bacteriostatic water to a 10mg MT1 vial to create a 5mg/ml concentration. Insert the needle and release water slowly against the glass wall, not directly onto the powder. Allow 5-10 minutes to dissolve without shaking.
How much bacteriostatic water for 10mg Melanotan 1?
The standard is 2ml of bacteriostatic water for a 10mg vial, creating a 5mg/ml concentration. This makes calculations simple: 0.1ml equals 0.5mg. You can use 1ml for a stronger concentration or up to 3ml for a weaker solution.
What is the difference between Melanotan 1 and 2?
Melanotan 1 is more selective for MC1R receptors and may have fewer off-target effects like appetite suppression and libido changes. MT2 typically works faster but has broader receptor activity. MT1 has more clinical research backing.
How long does Melanotan 1 take to work?
Most researchers report visible changes within 7-14 days of consistent use. Initial effects like facial flushing appear immediately after injection. Noticeable skin darkening typically begins after 5-7 daily doses during the loading phase.
Can I use Melanotan 1 without sun exposure?
Research suggests MT1 can stimulate melanin production without UV exposure, though results may be enhanced with some sun exposure. This was the original design purpose – to provide photoprotection before UV exposure.
What are the side effects of Melanotan 1?
Common side effects include facial flushing, nausea, and headache – typically mild and subsiding after the first few days. Less common effects include fatigue, appetite changes, and darkening of existing moles. Anyone with a history of skin cancer should not use MT1.
How should I store reconstituted Melanotan 1?
Store reconstituted MT1 in the refrigerator at 2-8C (35-46F) and use within 3-4 weeks. Never freeze reconstituted peptide. Keep protected from light and inspect for any cloudiness or particles before each use.
Final Thoughts: Getting Your Melanotan 1 Dosage Right
Accurate Melanotan 1 dosing comes down to proper reconstitution, understanding your syringe measurements, and starting conservatively. The calculations themselves are straightforward once you know your concentration.
Based on my research, the key principles for successful MT1 dosing are:
- Start with the lowest effective dose (0.25mg) and increase gradually
- Use the standard 2ml bacteriostatic water per 10mg vial for easy calculations
- Consider your Fitzpatrick skin type when planning your protocol
- Store reconstituted peptide properly and use within 3-4 weeks
- Purchase only from verified vendors with third-party testing
Remember that individual responses vary significantly. What works for one person may not work the same way for another. Monitor your response, adjust as needed, and prioritize safety throughout your research.
