Educational reference only. TNHL calculates and organizes user-entered values; it does not diagnose, prescribe, recommend doses, or replace guidance from a qualified professional.
MechanismMelanotan II is a synthetic analog of α-melanocyte-stimulating hormone studied for its ability to increase skin pigmentation and noted for inducing erectile activity as a side effect [1] . Early human trials identified effective daily doses in the range of 1–2 mg for tanning, with conservative protocols starting lower to minimize side effects such as nausea and flushing [2] [3] .
Dosing250–1000 mcg once daily (gradual titration over 8–12 weeks).
ReconstitutionAdd 2.0 mL diluent to a 10 mg vial.
StorageLyophilized: freeze at −20 °C (−4 °F) or below; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) ; use within 1–2 weeks.

Quickstart Highlights

Melanotan II is a synthetic analog of α-melanocyte-stimulating hormone studied for its ability to increase skin pigmentation and noted for inducing erectile activity as a side effect [1] . Early human trials identified effective daily doses in the range of 1–2 mg for tanning, with conservative protocols starting lower to minimize side effects such as nausea and flushing [2] [3] . This educational protocol presents a once-daily subcutaneous titration approach using practical dilution for clear insulin-syringe measurements.

ReconstituteAdd 3.0 mL bacteriostatic water → 3.33 mg/mL concentration.
Reference dose250–1000 mcg once daily (gradual titration over 8–12 weeks).

Dosing & Reconstitution Guide

A practical calculator-ready setup based on the imported protocol reference. Use these values as a math starting point, then verify every entry against your own vial, diluent, and professional guidance.

Standard / Gradual Titration (3 mL = 3.33 mg/mL)

Phase / setup Dose & frequency Volume / units
Week 1250 mcg (0.25 mg)7.5 units (0.075 mL)
Week 2500 mcg (0.5 mg)15 units (0.15 mL)
Week 3750 mcg (0.75 mg)22.5 units (0.225 mL)
Weeks 4–81000 mcg (1 mg)30 units (0.30 mL)
Week 8) 500–1000 mcg (1–2× weekly) 15–30 units (0.15–0.30 mL)

250–1000 mcg once daily (gradual titration over 8–12 weeks).

Reconstitution Steps

  1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall to avoid foaming; do not shake vigorously.
  3. Gently roll or swirl the vial until the powder is fully dissolved.
  4. Label the vial with the reconstitution date and store refrigerated at 2–8 °C (35.6–46.4 °F) , protected from light.

Protocol Overview

  • Goal: Increase skin pigmentation (tanning) through melanocortin receptor activation [1] .
  • Schedule: Daily subcutaneous injections for 6–8 weeks during loading phase, then maintenance dosing 1–2× weekly [3] .
  • Dose Range: 250–1000 mcg daily with gradual titration to minimize side effects.
  • Reconstitution: 3.0 mL per 10 mg vial (3.33 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized frozen at −20 °C (−4 °F); reconstituted refrigerated at 2–8 °C (35.6–46.4 °F); use within 1–2 weeks [7] .

Dosing Protocol

  • Suggested daily titration approach based on clinical research.
  • Start: 200–250 mcg daily; increase by 100–250 mcg increments every 1–2 weeks as tolerated [2] .
  • Target: 500–1000 mcg daily by Weeks 4–8 (studied effective range is 1–2 mg/day) [1] .
  • Frequency: Once per day (subcutaneous) during loading phase.
  • Cycle Length: 6–8 weeks for initial tanning, then switch to maintenance dosing.
  • Maintenance: 500–1000 mcg administered 1–2× per week to sustain pigmentation [3] .
  • Timing: Any consistent time; rotate injection sites to reduce irritation.

Storage Instructions

  • Proper storage preserves peptide stability and potency.
  • Lyophilized: Store at −20 °C (−4 °F) or below in dry, dark conditions; keep desiccated to minimize moisture exposure [7] .
  • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 1–2 weeks with bacteriostatic water preservative [7] .
  • Avoid freeze–thaw: Do not refreeze reconstituted solution; prepare aliquots if longer storage needed.
  • Allow vials to reach room temperature before opening to reduce condensation.

05 · How it works

How This Works

Melanotan II is a synthetic analog of α-melanocyte-stimulating hormone studied for its ability to increase skin pigmentation and noted for inducing erectile activity as a side effect [1] .

Early human trials identified effective daily doses in the range of 1–2 mg for tanning, with conservative protocols starting lower to minimize side effects such as nausea and flushing [2] [3] .

This educational protocol presents a once-daily subcutaneous titration approach using practical dilution for clear insulin-syringe measurements.

The library page pairs that educational context with calculator-ready vial math, so users can understand the protocol structure and then track their own entered values in one place.

06 · Daily habits

Lifestyle Factors

  • Keep meals, training, sleep, and recovery notes in the journal so trends are easier to review.
  • Track body metrics only if they are relevant to the user's goal and approved data sources.
  • Use consistent timing and logging habits so adherence data is meaningful.

07 · What to expect

Potential Benefits & Side Effects

  • Melanotan II observations should be recorded conservatively: expected research endpoints, tolerability notes, injection-site reactions when applicable, sleep, appetite, energy, mood, and any adverse or unusual response.
  • This section is not a claim of therapeutic benefit.

08 · Technique

Injection Technique

Pre-injection preparation
  • Wash hands with soap and water.
  • Wipe the vial stopper and chosen site with alcohol, then let both dry.
  • Confirm the vial concentration, calculator result, and intended draw amount before loading the syringe.
Injection procedure
  • Use the route and needle technique directed by a qualified professional or product instructions.
  • For subcutaneous injections, rotate sites and inject slowly to limit leakage and irritation.
  • Do not reuse needles or syringes.
Post-injection care
  • Dispose of sharps in a puncture-resistant container.
  • Return stored items promptly to the correct temperature.
  • Log dose, site, date, time, inventory change, and any observation.
