MT-2 (Melanotan 2 Acetate) 10mg

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.

Reconstitute: Add 3.0 mL bacteriostatic water → 3.33 mg/mL concentration.
Typical daily range: 250–1000 mcg once daily (gradual titration over 8–12 weeks).
Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U-100 insulin syringe.
Storage: Lyophilized: 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.

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

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

Week / Phase	Daily Dose	Units (per injection) (mL)
Week 1	250 mcg (0.25 mg)	7.5 units (0.075 mL)
Week 2	500 mcg (0.5 mg)	15 units (0.15 mL)
Week 3	750 mcg (0.75 mg)	22.5 units (0.225 mL)
Weeks 4–8	1000 mcg (1 mg)	30 units (0.30 mL)
Maintenance(after Week 8)	500–1000 mcg(1–2× weekly)	15–30 units(0.15–0.30 mL)

Frequency: Inject once daily subcutaneously during the initial 8-week tanning phase; transition to 1–2 injections per week for maintenance dosing to sustain pigmentation[3]. This schedule uses the standard 3.0 mL dilution for consistent unit measurements. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.

Schedule: Daily subcutaneous injections for 6–8 weeks during loading phase, then maintenance dosing 1–2× weekly[3]. Open source
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]. Open source

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]. Open source
Target: 500–1000 mcg daily by Weeks 4–8 (studied effective range is 1–2 mg/day)[1]. Open source

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]. Open source
Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 1–2 weeks with bacteriostatic water preservative[7]. Open source
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.

Important Notes

Practical considerations for consistency and safety.

Use new sterile insulin syringes for each injection; dispose in a sharps container immediately[9]. Open source
Rotate injection sites systematically (abdomen, thighs, upper arms) to reduce local irritation and scarring[10]. Open source
Clean vial stopper and injection site with alcohol swabs before each use; allow to air dry[11]. Open source
Inject slowly and steadily; wait a few seconds before withdrawing the needle.
Document daily dose, injection site, and any side effects to maintain consistency and track tolerance.
Safety warning: Do not exceed 2 mg per day; case reports document serious systemic toxicity and rhabdomyolysis at mega-doses (6 mg)[4]. Open source

How This Works

Melanotan II is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone that binds to melanocortin receptors, particularly MC1R and MC4R[1]. Activation of MC1R on melanocytes stimulates melanin production and distribution, resulting in increased skin pigmentation even without UV exposure[2]. Early Phase I studies in humans identified 0.025 mg/kg per day (approximately 1.5–2 mg for an average adult) as an appropriate dose, with measurable tanning observed after just five low doses administered over two weeks[1]. The peptide’s subcutaneous administration allows for steady melanocortin receptor activation, with effects accumulating over the course of daily injections during the initial tanning phase[3].

Lifestyle Factors

Complementary strategies for safe and effective outcomes.

UV exposure: Melanotan II increases melanin without UV, but some users combine with minimal UV exposure; always use appropriate sun protection to reduce skin cancer risk[6]. Open source
Hydration: Maintain adequate fluid intake, especially if experiencing nausea or appetite suppression.
Monitoring: Inspect moles and skin regularly for changes; seek dermatological evaluation if new or changing lesions appear[6]. Open source
Dose discipline: Adhere strictly to conservative dosing protocols; never exceed 2 mg per day to avoid serious adverse effects[4]. Open source

Injection Technique

Subcutaneous injection guidance from clinical best-practice resources[9][11].

Clean the vial stopper and injection site with alcohol swabs; allow both to air dry completely[11]. Open source
Use a 1 mL insulin syringe (29–31 gauge, ½ inch needle) for subcutaneous administration[9]. Open source
Pinch a fold of skin approximately 1 inch thick at the injection site (abdomen preferred, at least 2 inches from navel)[10]. Open source
Insert the needle at 45–90° depending on body composition; release the pinch after needle insertion[10]. Open source
Do not aspirate for subcutaneous injections; inject slowly and steadily[11]. Open source
Withdraw the needle at the same angle; apply gentle pressure with clean gauze if needed.
Rotate sites systematically to avoid lipohypertrophy or scarring[10]. Open source
Dispose of used syringes immediately in a proper sharps container; never reuse needles[9]. Open source
