What is Melanotan 2?
MT-II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), an endogenous neuropeptide and melanocortin agonist that affects many important biological processes. The melanocortin system is comprised of five distinct receptors that regulate functions such as melanogenesis, sexual arousal, and inflammatory response [4, 5].
Structurally, MT-II is classed as a cyclic heptapeptide, displaying a lactic ring and truncated form. MT-II primarily affects melanocortin receptor 1 (MC1R) and melanocortin receptor 4 (MC4R), which respectively modulate melanogenesis and sexual behavior. It additionally interacts with the MC3R receptor to influence energy expenditure and metabolic processes [4, 5, 6].
Melanotan 2 behaves similarly to its parent hormone, yet to a greater degree as it is 1000% more potent. Originally developed as a synthetic tanning agent, it has since undergone clinical analysis in a wider range of potential therapeutic contexts [5, 6].
Related derivatives of α-MSH are also under clinical evaluation, such as fellow melanocortin agonist melanotan 1 (MT-I). A precursor to MT-II, MT-I is a linear tridecapeptide that acts primarily on MC1R to elicit tanning effects, among other distinct functions.
Emerging studies indicate multiple useful contexts for the administration of melanotan 2. Continue reading as we uncover these additional benefits, as well as possible side effects, optimal dosages, and the best source for researchers to purchase quality melanotan 2.
Melanotan 2 Benefits | The A-Z Guide
Clinical research has indicated several key benefits of melanotan 2, namely:
Increased melanin production for a tanning effect
MT-II upregulates melanogenesis through its action at the MC1R receptor, increasing melanin production to darken the skin. The melanotropic agent also has photoprotective effects, shown to counteract photodamage and acute dermatoses from UV exposure in vulnerable subjects [1, 7].
Its activation of the third and fourth melanocortin receptors lends MT-II the potential to enhance sexual response in both male and female subjects, with particularly notable effectiveness in treating symptoms of male erectile dysfunction [3, 9, 10].
Cognitive and behavioral health
In its capacity as an MC4R agonist, MT-II has been linked in animal studies with reductions in autistic and addictive behavioral patterns. Researchers posit that this is due in part to the receptor’s upregulation of oxytocin, known to modulate antisocial behaviors such as social attunement and communication difficulties, as well as impulsivity [2, 11].
Several animal studies have revealed further effects of MT-II’s activity on melanocortin receptor 4, including diminished appetite as well as modified macronutrient preferences. The latter entails a reduction in fat and sugar consumption. This indicates the potential use of MT-II to treat obesity .
MT-II’s activity on melanocortin receptors 3 and 4 is evidenced to regulate blood glucose levels, suggesting its potential to counteract the effects of various metabolic diseases .
The role of the melanocortin system in fat storage and energetic expenditure suggests MT-II’s further effectiveness as a treatment for obesity. Clinical research involving animal subjects has linked MT-II with reduced adiposity .
Promising research into further potential therapeutic applications of MT-II is ongoing.
Melanotan 2 Side Effects
Melanotan 2 has been shown to elicit some side effects in clinical trials. Most side effects are minor, and there is a current lack of data on long-term side effects due to the peptide’s relatively novel status.
In one two-week trial involving three male subjects who received daily MT-II injections of 0.01 mg/kg, these side effects were reported  :
- Fatigue and drowsiness
- Spontaneous erections
- Stretching and yawning repeatedly
- Nausea ranging from moderate to severe
Further studies link MT-II with the development of moles as well as the increased pigmentation of pre-existing ones. Additional secondary effects include :
- Patchy skin pigmentation
- Streaks of pigmentation in the nails
- Flushing of the face
- Changes in taste
Severe side effects are uncommon and have included :
- Abdominal pain
- Heart palpitations
- Acute priapism necessitating medical intervention
Specialists discourage MT-II administration in subjects with symptoms of body dysmorphia, especially regarding skin tone. Most of the noted side effects are transient and cease with the termination of MT-II injections. They are also linked with factors such as comorbidities, drug interactions, and the use of artificial tanning beds.
Adverse effects are also significantly linked to improper dosage and contaminated peptides, typically sourced from disreputable vendors. Low-quality melanotan 2 products can include hazardous contaminants that lead to acute systemic toxicity. Thus, experts strongly advise that researchers acquire MT-II from strictly trusted sources and firmly abide by standard dosing guidelines .
While the information on long-term melanotan 2 use is pending, it is regarded by clinical specialists to have a favorable safety profile under proper conditions and handling.
How Long Does Melanotan 2 Take to Work
The rates of effectiveness in melanotan 2 vary depending on the desired therapeutic outcomes. Further, some potential benefits are evidenced only in clinical trials involving animal subjects, revealing latency periods that may change in human subjects.
With such factors in mind, here are the current findings on the primary evidenced benefits of melanotan 2:
In many clinical trials on human subjects, melanotan 2 has been proven as an effective synthetic tanning agent, rendering optimal results in concert with scheduled windows of UV exposure. While trial lengths vary, most have yielded visible tanning results within one to two weeks of daily injections. These findings are dose-dependent.
Although visible tanning effects show some latency, research has shown the photoprotective benefits of MC1R stimulation to be immediate.
The pro-erectile effects of MT-II in both animal and human studies are well-documented, owing to its affinity for melanocortin receptors 1, 3, and 4. In one important study, ten men with psychogenic ED were given MT-II injections of 0.025 to 0.157 mg/kg. Eighty percent of the subjects developed erections of notable duration and rigidity with latency periods ranging from 15 to 270 minutes. Another study on men with organic ED yielded similar results. Increased sensations of sexual desire were also reported.
The role of melanocortin receptors 3 and 4 in boosting sexual arousal in females has also been noted. A synthetic peptide and MT-II derivative called PT-141 has been proven to increase sexual response in premenopausal women within 24 hours of administration.
In a study on male mice exhibiting autism features per the MIA model, a complete reversal of autistic behavioral features was observed within seven days of daily MT-II administration. This suggests the potential of MT-II as a rapidly effective autism treatment.
Regarding addictive behavior and effects, MT-II has been shown to diminish alcohol consumption while reducing its neurotoxic effects in animal studies. In one of these, alcohol-seeking behavior was immediately reduced and curtailed for up to 24 hours after MT-II injection. This is theorized to be affected through MC3R and MC4R stimulus and is thought to pertain to additional addictive substances, pending further research.
Several studies involving animals have shown that MT-II injections can significantly decrease appetite and modify macronutrient preferences within 24 hours of administration.
While one animal study showed MT-II to modulate insulin sensitivity within 24 hours of injection, another showed significant improvements in insulin sensitivity after 10 days of continuous administration in obese rats.
Additional studies in rodents indicate the effectiveness of MT-II in weight loss and reducing body fat. In one study, a 40-day trial of daily MT-II administration in rats yielded significant decreases in body fat and adiposity in all subjects. This included increased thermogenesis.
Melanotan 2 Dosage Guide
- The base therapeutic dose for the subcutaneous injection of MT-II is 500 mcg per day.
- It is recommended to start with a low dose and gradually increase it to minimize side effects.
- The maximum dose seen in clinical trials is 1mg/kg daily.
- Trials range from one to more weeks. The indefinite use of MT-II is not recommended. Administration schedules vary from one to several weeks.
- To maximize tanning benefits, it is recommended to inject MT-II before regular UV exposure sessions of 60 minutes or less.
- Tiered dosing frequency is recommended, starting with a loading phase and then proceeding to a maintenance phase.
To correctly reconstitute melanotan 2 for injection, the following items are required:
- Vial of bacteriostatic water
- Vial of lyophilized MT-II
- Alcohol wipes
- Sterile syringe
The process of MT-II reconstitution before an injection is as follows:
- Wipe all items down with alcohol to reduce the risk of contamination. This includes the uncapped vials.
- Using the syringe, withdraw a small amount of bacteriostatic water, usually 1-2 mL. The exact amount depends on the dose.
- Gradually inject the bacteriostatic water into the vial of MT-II, allowing it to slowly drip down the side and evenly dissolve the powder.
- Avoid stirring or shaking the vial, as doing so may damage the peptides. When it is fully mixed, the solution will be transparent.
- Properly store and refrigerate excess solution for subsequent injections.
Melanotan 2 Cycle | A-Z
Melanotan 2 is not indicated for indefinite use and should be administered in cycles of varying lengths and quantities, depending on desired therapeutic outcomes. In clinical trials, duration and dosage specifics vary widely, so researchers are advised to familiarize themselves with the latest studies and best practice guidelines.
When it comes to injecting MT-II for sunless tanning, specialists agree that it is best to start at a low dose and gradually increase, moving between loading doses and maintenance doses. Let’s explore these phases [7, 24]:
The starting dose can be as small as 250mcg and is intended to allow the assessment of the subject’s reaction. Ideally, it would elicit no noticeable effects.
If no acute adverse reactions are noted, the dosage can be increased gradually to 500mcg-1mg daily. During this phase, regular UV exposure will result in visible tanning.
This phase begins when the subject has obtained the desired level of tanning. The frequency of administration can be cut down to as little as once a week, and the dosage may be modified.
Depending on the skin type of the subject, visible tanning effects should last for up to several months after cessation of the therapy. While there is no standard indication for the duration of use, most clinical trials last from one to several weeks.
