MT-2 (Melanotan 2 Acetate) – 10mg

Table of Contents

  • Quickstart Highlights

MT-2 (Melanotan II Acetate) 10mg protocols focus on this synthetic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH), studied for its ability to stimulate melanin production in the skin. By activating melanocortin receptors, MT-2 may promote tanning response, increase skin pigmentation, and influence appetite and libido pathways. This guide outlines a subcutaneous administration approach optimized for the 10 mg vial format.

  • Reconstitute: Add 2.0 mL bacteriostatic water → 5 mg/mL concentration
  • Typical dosing range: 250–1000 mcg per dose (subcutaneous)
  • Easy measuring: At 5 mg/mL, 1 unit = 0.01 mL = 50 mcg (0.05 mg) on a U-100 insulin syringe
  • Storage: Lyophilized: store at −20 °C; after reconstitution, refrigerate at 2–8 °C and use within 2–3 weeks
  • Protocol Overview

Concise summary of the subcutaneous regimen.

  • Goal: Support skin pigmentation (tanning response) via melanocortin receptor activation
  • Schedule: Daily injections during the loading phase, then maintenance dosing
  • Dose Range: 250–1000 mcg per dose
  • Dosing Protocol

Suggested approach for the 10 mg vial format.

  • Start: 250 mcg once daily to assess tolerance
  • Loading phase: 500–1000 mcg daily until desired pigmentation is achieved
  • Maintenance: 500 mcg 1–2 times per week as needed
  • Frequency: Once daily (loading), then reduced frequency for maintenance
  • Vial Duration: One 10 mg vial typically lasts 10–40 days, depending on protocol
  • Mechanism of Action

MT-2 (Melanotan II) is a synthetic analog of α-melanocyte-stimulating hormone (α-MSH) that binds to melanocortin receptors, primarily MC1R in melanocytes. Activation of MC1R increases cyclic AMP (cAMP), which stimulates melanin production and leads to darker skin pigmentation.

Beyond melanogenesis, MT-2 also interacts with other melanocortin receptors involved in appetite regulation and sexual function. This is why users in research settings have reported changes in appetite suppression and libido modulation alongside tanning effects.

  • Potential Benefits & Side Effects

Observations based on preclinical research and reported use.

Potential Benefits:

  • May promote increased skin pigmentation and tanning response
  • May reduce the need for UV exposure to achieve a tan
  • May influence appetite regulation pathways
  • May affect libido in some users

Possible Side Effects:

  • Nausea, flushing, or facial redness (especially during the loading phase)
  • Temporary loss of appetite
  • Increased freckling or uneven pigmentation
  • Spontaneous erections reported in some cases
  • Not approved for human cosmetic use in many regions; remains investigational
