What is Melanotan 2?
Melanotan 2 (MT-II) shows potential in several applications, from sunless tanning to boosting cognitive and sexual health [1, 2, 3].
This synthetic peptide is an analog of alpha-melanocyte-stimulating hormone (α-MSH), a melanocortin agonist with various physiological roles. The body’s melanocortin system consists of five different types of receptors that regulate processes such as melanin production, inflammatory response, and sexual function [4, 5].
MT-II has a cyclic truncated form and acts primarily upon melanocortin receptor 1 (MC1R) and melanocortin receptor 4 (MC4R), respectively involved in melanogenesis and the regulation of sexual behavior. It also has some effect on MC3R receptors, which affect metabolism and energy levels [4, 5].
As a synthetic analog of α-MSH, melanotan 2 fulfills similar functions, albeit to a higher degree due to its potency. Though it was initially studied as a sunless tanning agent, clinical analysis has expanded to explore its further potential applications [4, 5].
Additional α-MSH derivatives are also being heavily studied, namely melanotan 1 (MT-I). Though MT-I and MT-II both act on the melanocortin receptors, they have distinct structures and functions. Structurally, MT-1 is long and linear, while MT-II has a circular amino acid arrangement.
A highly modified α-MSH derivative called PT-141 is also found in both research and clinical settings, namely as a treatment for low sex drive [6, 7].
Ongoing investigation indicates numerous beneficial applications of melanotan 2. Read on to learn these and more, including proper dosage, potential side effects, and where to source the best melanotan 2 for your research.
Melanotan 2 Benefits | The A-Z Guide
Clinical studies have revealed numerous potential benefits of safely administered melanotan 2. Here are some of the most notable benefits to date:
Sunless Tanning Agent
Melanotan 2 is a potent melanotropic agent, boosting melanin synthesis to visibly darken the skin after several doses. The photoprotective properties of increased melanin also potentially reduce the risk of certain types of skin cancer and sun damage in susceptible individuals, while minimizing the need for UV exposure to obtain the desired tanned appearance. Subcutaneous injection is the preferred method of administration for this purpose [1, 6].
Treatment of Symptoms of Erectile Dysfunction
As a melanocortin 4 receptor agonist, MT-II has been shown to modulate sexual response in both male and female subjects. The melanocortin 3 receptor may also play a role in this action. Its effectiveness in eliciting penile erection in men with erectile dysfunction (ED) is particularly notable. While the exact mechanisms of this function are still under investigation, studies indicate that MT-II powerfully affects sexual arousal through the hypothalamus [3, 8, 9].
Addressing Symptoms of Autism
At least one animal study has shown MT-II to reduce aberrant behavioral patterns associated with autism, namely poor social responsiveness, repetitive actions, and communication difficulties. This is thought to be achieved through stimulation of the melanocortin 4 receptor, which upregulates cerebral oxytocin, a key hormone in modulating social attunement. Research is ongoing in this context .
Reduction of Addictive Behaviors
MT-II is reportedly associated with decreased alcohol consumption in animal studies, achieved through the hypothalamic activity of the melanocortin 4 receptors. In one study it was shown to reduce alcohol consumption and increase water intake among alcohol-preferring rats. Research indicates that the melanocortin system also plays a role in addictive responses to narcotics such as opioids, cocaine, and amphetamines. Beyond addiction, it may also play a role in regulating impulsive behavior. Continued analysis is underway in this regard [10, 11].
MC4R signaling in the hypothalamus is proven to mediate food intake, both reducing the appetite and altering macronutrient preference to reduce fat and sugar consumption in animals. The application of melanotan 2 in this context may have implications for the treatment of obesity, especially in MC4R-deficient subjects who are prone to the disease [12, 13, 14].
Blood Sugar Regulation
Studies in mice indicate that MT-II’s stimulation of the MC-3 and MC-4 receptors affects blood glucose levels, augmenting insulin sensitivity. In this capacity, it may counter metabolic disease symptoms. Studies are underway to ascertain the full benefits of this application .
Improved Body Composition
Tying into the neuropeptide’s above-mentioned effects on appetite and metabolism, MT-II has been shown to reduce body fat and increase lean muscle mass in animal studies. MT-II reduces adiposity through both the induction of caloric deficit and inhibiting the retention of subcutaneous and visceral fatty tissue. The role of the melanocortin system in regulating energy expenditure and fat storage is under study for therapeutic applications in both obese and healthy subjects [16, 17].
While this is an impressive list of benefits, it is by no means exhaustive. Emerging research on melanotan 2 continues to uncover new and exciting potential benefits in a range of clinical contexts.
Melanotan 2 Side Effects
There have been some side effects associated with melanotan 2 in clinical trials. Most of these are minor, and studies on long-term side effects are pending. Here we will explore the primary findings.
In one study, three healthy male subjects receiving daily subcutaneous MT-II injections dosed at 0.01 mg/kg variously reported the following side effects during the two-week course of administration :
- Moderate to severe nausea
- Repetitive yawning and stretching
- Spontaneous erections
Additional studies have linked MT-II administration with the darkening of pre-existing naevi (moles) and the development of new ones. Other minor effects include :
- Uneven skin pigmentation
- Nail pigmentation
- Facial flushing
- Alteration of taste
More serious side effects are rare and may include :
- Acute priapism requiring medical intervention
- Heart palpitations
- Abdominal pain
Clinicians caution against the use of melanotan 2 in subjects with body dysmorphic disorders, particularly as related to skin tone. In many cases, side effects subside with the discontinuation of MT-II and are affected by additional factors such as the use of tanning beds, comorbidities, and drug interactions.
Researchers note that adverse effects are often linked with impure products from disreputable sources as well as improper dosage. Low-grade MT-II products may contain dangerous contaminants that can cause severe systemic toxicity. For these reasons, researchers must purchase MT-II from strictly trusted suppliers and closely adhere to the dosage guidelines put forth by experts .
Again, data on the long-term effects of melanotan 2 is unavailable. However, leading clinicians consider it to have a generally favorable safety profile when correctly handled by qualified researchers.
Melanotan 2 Dosage Guide
Melanotan 2 is not manufactured for human use, so there are no official standard dosage indications at this time .
However, qualified researchers have put forth the following melanotan 2 dosage guidelines for sunless tanning :
- MT-II may be administered through subcutaneous injection with a starting therapeutic dose of 250mcg, increased incrementally to the typical daily dosage of 500mcg.
- This is considered the optimal dose for beneficial results and manageable side effects. However, it may be subject to variation based on desired therapeutic outcome.
- Dosing schedules are subject to variation, with durations ranging from one to several weeks. MT-II is not indicated for indefinite use.
- Researchers should start with a low dose and slowly increase it.
- For darkening of the skin, MT-II is often administered prior to scheduled tanning times, typically lasting no more than 60 minutes.
To properly reconstitute and inject melanotan 2, researchers should have the following supplies:
- Vial of lyophilized MT-II
- Vial of bacteriostatic water
- Sterile syringe
- Alcohol wipes
To reconstitute MT-II before injection, follow these steps:
- Remove the vial tops and wipe down their surfaces with the alcohol swab to prevent contamination and infection.
- Insert the sterile syringe into the vial of bacteriostatic water and withdraw the desired amount, typically 1-2 ml, dependent on the dose.
- Slowly inject the bacteriostatic water into the MT-II vial, letting it trickle down the side of the vial and gradually dissolve the powder.
- Do not shake or stir the vial, as this can compromise the peptides. The solution will appear clear when it is fully mixed.
- Refrigerate the unused solution.
