Description
Melanotan II (MT-II) is a synthetic analog of the naturally occurring hormone α-MSH. This hormone regulates skin pigmentation and is also involved in several other physiological functions including appetite and sexual arousal. When administered, Melanotan II stimulates melanocortin receptors which then trigger melanin production in the skin. Melanin is the pigment responsible for the coloration of skin, hair, and eyes and also plays a key role in UV protection.
Melanotan II is typically injected subcutaneously. After entering the bloodstream, it binds to melanocytes stimulating them to produce and release more melanin. This leads to gradual skin darkening over time, mimicking the effects of a sun-induced tan without significant UV exposure.
Additionally, MT-II binds to other melanocortin receptors like MC3R and MC4R, which are involved in appetite regulation, metabolism, and sexual function. These off-target interactions help explain some of the peptide’s secondary effects, such as libido enhancement and appetite suppression.
Benefits of Using Melanotan II :
- Sunless Tanning
- Enhanced Libido
- Appetite Suppression
Potential Side Effects :
- Gastrointestinal Issues : The most commonly reported side effects include nausea, vomiting, and stomach cramps, particularly during the early stages of use. These symptoms are often dose-dependent and may diminish as the body acclimates to the peptide.
- Hyperpigmentation and Skin Changes : Changes in mole and freckle pigmentation.
Dosage Guidelines and Administration :
- Reconstitute with 2ml Bacteriostatic water
- Starting Dose : 250 mcg daily (5 units), especially for first-time users
- Daily injection schedule for steady melanocortin receptor injection
- Titrate up to 0.5–1 mg per day based on tolerance and results
- Injection Timing : Administer in the evening to mitigate nausea
- Cycle : 4-6 weeks or longer
- Space injection to 3 times per week when you reach the tanning goal to keep it steady.
It’s critical not to exceed recommended doses, as overuse increases the risk of side effects, including hyperpigmentation and nausea.
