What is Melanotan II?
Melanotan II is a synthetic cyclic peptide analog of alpha-melanocyte-stimulating hormone, also known as alpha-MSH. It is mainly discussed in research for its ability to activate melanocortin receptors involved in skin pigmentation.
In research and clinical discussions, Melanotan II is most commonly associated with increased melanin production, tanning response, appetite changes, nausea, flushing and erectile activity as a noted side effect.
Melanotan II Reconstitution Example
The example below is based on a common 10mg Melanotan II vial mixed with 3.0mL bacteriostatic water.
Reconstitution Maths
10mg ÷ 3.0mL = 3.33mg/mL
3.33mg/mL = 3,333mcg/mL
1 unit on a U-100 syringe = 0.01mL
3,333mcg/mL × 0.01mL = approximately 33.3mcg per unit

Frequency and Timing Notes
Melanotan II is commonly discussed as once-daily subcutaneous use during an initial loading phase. The source protocol then discusses moving to 1-2 injections per week for maintenance after pigmentation has developed.
Timing is usually less important than consistency, conservative titration and monitoring tolerance. Lower starting amounts are commonly discussed because nausea, flushing and appetite changes can be dose-related.
Reconstitution Steps
- Confirm the vial size before calculating concentration.
- Draw 3.0mL bacteriostatic water using sterile technique.
- Inject the bacteriostatic water slowly down the inside wall of the vial.
- Avoid blasting the powder directly and avoid creating foam.
- Gently swirl or roll the vial until the powder fully dissolves.
- Do not shake vigorously.
- Label the vial with the reconstitution date and concentration.
- Store the reconstituted vial in the refrigerator at 2-8°C, protected from light.

- 16-week example: 10 vials × 3.0mL = 30mL total, so 3 × 10mL bottles may be needed.
Alcohol Swabs
- Per administration: one swab for the vial stopper and one for the injection site.
- Daily example: approximately 14 swabs per week.
- 8 weeks: around 112 swabs, so 2 × 100-count boxes may be needed.
- 12 weeks: around 168 swabs, so 2 × 100-count boxes may be needed.
- 16 weeks: around 224 swabs, so 3 × 100-count boxes may be needed.
Protocol Overview
- Goal discussed in research: increased skin pigmentation through melanocortin receptor activation.
- Schedule example: daily subcutaneous use during a 6-8 week loading phase.
- Maintenance example: 500-1,000mcg, 1-2 times weekly after the loading phase.
- Common amount discussed: 250-1,000mcg daily with gradual titration.
- Example reconstitution: 3.0mL bacteriostatic water per 10mg vial.
- Concentration: approximately 3.33mg/mL.
- Storage: lyophilised frozen, reconstituted refrigerated and used within 1-2 weeks.
Example Dosing Protocol
- Start: 200-250mcg daily in conservative examples.
- Titration: increase by around 100-250mcg every 1-2 weeks as tolerated.
- Target example: 500-1,000mcg daily by weeks 4-8.
- Loading phase: 6-8 weeks is commonly discussed for initial pigmentation.
- Maintenance phase: 500-1,000mcg, 1-2 times weekly is commonly discussed to sustain pigmentation.
How Melanotan II Works
Melanotan II binds to melanocortin receptors, especially MC1R and MC4R. Activation of MC1R on melanocytes can stimulate melanin production and distribution, which is why it is discussed in tanning and pigmentation research.
MC4R activation is one reason Melanotan II is also associated with erectile activity, libido changes and appetite effects in research and user reports.
The source protocol notes that effects may accumulate over repeated daily administrations during the initial loading phase.
Potential Benefits Discussed in Research
- Skin pigmentation and tanning research
- Melanocortin receptor activation
- MC1R and melanin pathway discussions
- Observable tanning effects after repeated administrations in research contexts
- Maintenance dosing to sustain pigmentation after a loading phase
- Erectile activity as a noted side effect in some men
Common Side Effects and Risks
- Nausea, often dose-related
- Facial flushing and increased skin warmth
- Reduced appetite
- Mild fatigue
- Spontaneous erections or increased libido in some men
- Injection-site redness, stinging or irritation
- Possible transient heart rate or blood pressure changes at higher amounts
- Potential mole or pigmentation changes
- Serious toxicity has been reported in case literature at very high amounts
Storage Instructions
- Lyophilised powder: store frozen at around -20°C or below in dry, dark conditions.
- After reconstitution: refrigerate at 2-8°C.
- Use window: commonly discussed as within 1-2 weeks after reconstitution.
- Avoid: heat, sunlight, moisture, contamination and repeated freeze-thaw cycles.
- Do not refreeze: reconstituted solution should generally not be refrozen.
- Practical note: allow cold vials to reach room temperature before opening to reduce condensation exposure.
Injection Technique Notes
This section is general educational information only. It is not personal injection instruction.
- Use a new sterile insulin syringe for each administration.
- Clean the vial stopper and injection site with alcohol and allow both to dry completely.
- Common subcutaneous sites discussed include abdomen, thighs and upper arms.
- Rotate injection sites systematically to reduce irritation, scarring and lipohypertrophy risk.
- Pinch a fold of skin and insert into subcutaneous tissue at an appropriate angle.
- Do not aspirate for subcutaneous injections.
- Inject slowly and steadily.
- Withdraw the needle at the same angle and apply gentle pressure if needed.
- Do not rub the site.
- Dispose of used sharps safely in a sharps container.
Lifestyle Factors That May Matter
- Sun protection: pigmentation does not remove the need for sunscreen or responsible UV exposure.
- Skin monitoring: regularly check moles and pigmentation changes, especially new or changing lesions.
- Hydration: adequate fluid intake may matter if nausea or appetite suppression occurs.
- Dose discipline: the source protocol strongly warns against excessive amounts and highlights case-report toxicity at very high doses.
- Tracking: documenting amount, date, site and side effects can make tolerance patterns easier to review.
