Melanotan II is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Melanotan II is administered via subcutaneous injection at 250-500 mcg per injection every other day. Subcutaneous injections into the abdominal fat or thigh are most common. Proper reconstitution with bacteriostatic water is required first.
How Do You Inject Melanotan II?
Melanotan II is administered via subcutaneous injection. For most researchers, subcutaneous injection is the standard approach — it's simple, relatively painless, and effective for Non-selective melanocortin receptor agonist compounds.
This guide covers injection technique, site selection, needle choices, and common mistakes.
How Do You Prepare for a Melanotan II Injection?
Step 1: Wash your hands thoroughly.
Step 2: Clean the top of the Melanotan II vial and BAC water vial with alcohol swabs. If not yet reconstituted, see our Melanotan II reconstitution guide.
Step 3: Draw your dose (250-500 mcg per injection) into an insulin syringe. Use our calculator for exact units.
Step 4: Clean the injection site with an alcohol swab and let it dry.
What Is the Correct Injection Technique?
Subcutaneous (most common): Pinch a fold of skin — typically abdominal fat 2+ inches from the navel, or the thigh. Insert the needle at a 45-degree angle. Push the plunger slowly and steadily. Hold for 5 seconds, then withdraw.
Intramuscular (less common for Melanotan II): Insert the needle at 90 degrees into the muscle (deltoid or vastus lateralis). This route provides faster absorption but isn't necessary for most peptide protocols.
Rotate injection sites to prevent lipodystrophy (fat tissue changes from repeated injections in the same spot).
What Size Needle Should You Use?
For subcutaneous Melanotan II injections, 29-31 gauge insulin needles (½ inch or 8mm) are standard. These are thin enough to be nearly painless while long enough for proper subcutaneous delivery.
Use a fresh needle for every injection. Never reuse or share needles.

Mild redness, swelling, or itching at the injection site is normal and typically resolves within hours. Small bruises can occur, especially if you hit a capillary.
If you experience persistent pain, swelling, warmth, or redness lasting more than 24 hours, discontinue and consult a healthcare provider — these may indicate infection.
Bottom Line on Melanotan II Injection
Melanotan II is administered via subcutaneous injection at 250-500 mcg per injection every other day. Subcutaneous injection with a 29-31 gauge insulin needle into abdominal fat is the standard technique. Rotate sites and use a fresh needle every time.

Frequently Asked Questions
What is Melanotan II?
Melanotan II (Melanotan II (cyclic α-MSH analog)) is a Non-selective melanocortin receptor agonist. Synthetic cyclic α-MSH analog with non-selective activity across MC1, MC3, MC4, and MC5 receptors. It is researched for rapid skin darkening, appetite suppression, erectile function enhancement, increased libido.
What is the recommended Melanotan II dosage?
Common dosages: 250-500 mcg per injection administered every other day via subcutaneous injection. Cycle length: 2-4 weeks for tanning effects. Half-life: not precisely established; effects persist longer than MT-I. Use our peptide calculator for exact reconstitution math.
What are the side effects of Melanotan II?
Extensive adverse effects: nausea, vomiting, facial flushing, involuntary erections, yawning, loss of appetite. Serious reports of rhabdomyolysis, renal infarction, posterior reversible encephalopathy syndrome, and sympathomimetic toxicity. Increased melanoma risk, atypical moles, melanonychia (nail darkening). Dose-dependent toxicity.
Is Melanotan II safe?
Melanotan II has shown a preliminary safety profile in research. Not FDA-approved. Banned for human use in many jurisdictions. Warnings issued by US FDA, UK MHRA, and other health agencies. WADA banned. All research should follow appropriate safety protocols.
