What is Melanotan 2?

Melanotan 2 is a synthetic peptide that mimics alpha-melanocyte-stimulating hormone (α-MSH), a naturally occurring substance secreted from the pituitary gland [1].

The α-MSH peptide, along with all the other peptides in the body, plays an important role in regulating various bodily functions. They produce chemical signals by binding to receptors that are found throughout the body. Specifically, α-MSH binds to a set of receptors called melanocortin receptors [2].

There are 5 types of melanocortin receptors and each has a slightly different effect on the body. MC-1R is responsible for signaling the body to produce more melanin, the substance responsible for darkening skin and hair. Melanotan 2 can bind to the same receptors and may offer similar benefits in test subjects. 

The other melanocortin receptors have different roles. For example, the MC-3R plays a role in regulating appetite and energy and MC-4R plays a role in regulating sexual behavior and erectile function. That's why past studies have linked melanotan 2 to other effects such as heightened libido and decreased body fat levels in test subjects. 

Researchers unfamiliar with melanotan 2 may note that it differs slightly from melanotan 1. We’ll explore the main similarities and differences between these two peptides in the next section.

Melanotan 1 vs. Melanotan 2

What's the difference between melanotan 1 (MT-1) and melanotan 2 (MT-2)?

The main difference lies in their chemical structure. While both peptides have a chemical structure that closely resembles α-MSH, they differ in several important ways. Melanotan 1 is a straight, longer peptide while melanotan 2 is a shorter, circular peptide.

These chemical differences mean that these peptides bind to different melanocortin receptors and stimulate them differently. This means they have some effects in common, but also produce some different effects.

Similarities:

• Both melanotan 1 and melanotan 2 appear to darken the skin when administered to test subjects.
• Both peptides have similar side effects: flushing, nausea, darkening of moles.

Differences:

• Studies have linked melanotan 2 dosing to increased libido in test subjects. This effect has not been observed in MT-1 studies.
• Melanotan 2 has a longer half-life than MT-1, so it has a more flexible dosing schedule. In past studies, test subjects have been administered MT-2 once per day, while MT-1 studies have typically involved twice-daily injections. 
• Melanotan 1 is approved by the FDA and in the EU as a prescription medication for patients with erythropoietic protoporphyria; MT-2 isn't.

Having reviewed the main similarities and differences between MT-1 and MT-2 we will turn our attention to the main benefits and uses of MT-2.

Melanotan 2 Benefits and Uses

Past studies have linked melanotan II to a number of effects in test subjects. Here's a shortlist of those.

• Tanning and skin darkening. Studies have shown that melanotan 2 reduces the chance of test subjects getting sunburn and appears to protect the skin from sun damage. Some studies have suggested that MT-2 can even reduce the chance of getting skin cancer [3, 4, 5].
• Reduces hunger. Some research has found that melanotan II plays a role in regulating appetite. In animal studies, It has been found to reduce fat storage and change food preferences away from fatty foods [6, 7, 8].
• Regulating blood sugar. Some research has indicated that melanotan 2 doses may play a role in regulating blood sugar [9]. This indicates that further research into the ability of MT-2 to regulate blood sugar levels may be merited. 
• Improving impulse control and addictive behavior. Animal studies have found that melanotan 2 doses can help regulate impulsive behavior [10]. This suggests that further research is warranted. 
• Increasing libido and improving sexual function. Several studies have linked MT-2 to increased libido in test subjects [11, 12]. In fact, it was originally developed as a way to treat hypoactive sex drives in both male and female research subjects. 

While these purported effects may spike the interest of peptide researchers, it should be stressed that melanotan 2 is a research chemical and has no safe dosage in human test subjects. So, what is known about melanotan 2 side effects?

Melanotan 2 Side Effects

What side effects does melanotan 2 produce in test subjects? Here’s a shortlist [3]:

• Yawning
• Stretching
• Decreased appetite
• Increased sexual arousal and libido
• Darkening facial hair
• Darkening moles
• Flushing
• Nausea
• Lethargy
• Dizziness

Despite these side effects, a review of research on melanotan 2 has concluded that “side effects observed in clinical trials are largely minor” [3]. 

Let’s dive into how melanotan 2 has been dosed in past clinical studies.

Melanotan 2 Dosage Calculator and Guide

After reviewing the background, effects, and overall safety profile of melanotan 2, we’ll now explore how this research chemical has been administered in past clinical studies. We must stress that melanotan 2 studies are lacking and this merits further research.  

Recommended melanotan 2 dosage

Melanotan 2 has not been evaluated or approved by the United States Food and Drug Administration and has no recommended dosage or protocol.

Dosage regimes used in past studies may help inform peptide researchers when planning future experiments [3].

For erectile dysfunction in men, the available research reveals that melanotan 2 has been administered at doses of 0.025mg/kg (roughly 0.011mg/lb), with a total of four doses separated by a 48 hour period. This is equal to a 2mg dose for a 175lb person [3, 11].

For tanning, research reports that the peptide has been used in doses of 0.01mg/kg (0.0045mg/lb) daily for up to two consecutive weeks. This would be equal to 0.8mg/daily for a 175lb individual [4].

Experts recommend using the lowest effective of the peptide and initiating research with melanotan 2 at a lower dosage within the range of 0.25-0.5mg/daily.

Based on the research, here is a sample melanotan 2 dosing protocol to be used for reference during tanning research:

• Daily Dosage: 0.25-0.5mg
• Frequency: Once-daily subcutaneous injections
• Study Duration: Up to 14 days. This cycle has not been repeated according to the available research. Accordingly, grant at least a few months’ washout period or preferably administer the cycle only annually.
• Notes: Researchers are recommended to initiate research at the lowest possible dose. A 10mg melanotan 2 vial is sufficient for two courses at 0.25mg/daily or a single course at 0.5mg/daily.

Getting the right equipment

To judge and calculate the correct melanotan 2 dose to administer to test subjects, researchers need to know a few things. These are as follows: 

• Size of the syringe. Most peptide researchers opt to use insulin syringes to administer melanotan 2 because these have thin, short needles. There are several sizes, but they usually come in one of two sizes: 10 International Units (IUs) = 0.1 milliliters (mL) or 100 IUs = 1 mL.
• How much melanotan 2 is in the vial. Usually, melanotan 2 vials come in 2 milligrams (mg) or 10 mg. 

For reasons of brevity, the following examples will assume that researchers are using a 100 IU (1 mL) syringe and 10 mg vial of melanotan II.

How to reconstitute melanotan 2

When purchased as a reference material, melanotan 2 is shipped as a freeze-dried powder. This must be reconstituted with sterile water such as bacteriostatic water prior to use. 

To reconstitute melanotan 2 and make it injectible, researchers may follow these directions:

1. Remove the top of the melanotan 2 vial. Wipe the rubber stopper with an alcohol swab to sterilize it.
2. Remove the top of the bacteriostatic water. Wipe that rubber stopper with alcohol too. This is to reduce the chance of infection.
3. Insert the syringe into the vial of water. Hold it upside down and take out the water. Most researchers use 1 or 2 mL, but researchers should be aware that the amount will affect the melanotan 2 dose. 
4. Inject the water slowly in the vial of melanotan 2, aiming at the side (not the powder).
5. Refrigerate for a few hours or overnight until the powder dissolves. The vial can be swirled or tilted but not shaken. 

Dosage calculator

These calculations assume that researchers have access to a syringe size of 1 mL and have reconstituted 10 mg of melanotan 2 with 1 mL of bacteriostatic water:

• 250 mcg (0.25 mg) dose = 3 IUs
• 500 mcg (0.5 mg) dose = 5 IUs
• 750 mcg (0.75 mg) dose = 8 IUs
• 1 mg dose = 10 IUs

These calculations assume that researchers have access to a syringe size of 1 mL and have reconstituted 10 mg of melanotan 2 with 2 mL of bacteriostatic water:

• 250 mcg (0.25 mg) dose = 5 IUs
• 500 mcg (0.5 mg) dose = 10 IUs
• 750 mcg (0.75 mg) dose = 15 IUs
