2.  Description:

Melanotan (MT) and Melanotan II (MT-II) are both analogs of the alpha-melanocyte 

stimulating hormone (α-MSH) which is produced within the pituitary gland. Along with 

other melanocortins, they are responsible for various internal human functions including skin

and hair pigmentation, appetite, libido and physical sexual arousal. Whilst these effects have 

been observed in both sexes, it is worth noting that increases in libido and sexual function 

are exclusive to MT-II. This article will primarily look at the tanning and pigmentation properties 

of the hormone, though it would be foolish to ignore the other effects which are discussed further 

in the Side Effects section.

3.  Applications:
Melanotan II makes you tan darker very quickly.

Melanotan II has tanning activity in humans given only 5 low doses every other day by subcutaneous 

injection.” The side effects reported were mild nausea and a “stretching and yawning complex” that 

correlated with spontaneous penile erections. In addition to this, “tanning-in” of cuts, bruises and 

other skin damage has also been reported by some users in online bodybuilding forums.Melanotan II 

(MT-II) and Melanotan (MT) are both analogs of the alpha-melanocyte stimulating hormone

(α-MSH) which is produced within the pituitary gland.Melanotan II is a designed to stimulate

the body’s tanning response with minimal exposure to sunlight.Lyophilized Melanotan II is 

stable at room temperature for 90 days,however it should be stored in a freezer below -8C 

for any extended period of time. After reconstituting Melanotan II should be refrigerated 

at temperatures not to exceed 36 F.


Peptide and Human Growth Steroid Melanotan II Melanotan 2 for Lasting Tan

Melanotan is a tanning peptide that stimulates the production of melanin in the body to foster a deep, natural tan.This is the body's way of protecting itself from too much sun exposure by increasing the

level of melanin in the body.Melanin is your body's natural response to UV damage.The end result is a darkening of the skin.

How it works?

Melanotan 2 works by stimulating the release of the pigment melanin from the skin.Less UV exposure

is necessary with Melanotan 2 compared to "normal tanning", and the tan that occurs with tanning injections is deeper and longer lasting than an individual's "normal tan".Melanotan works best (has

the most noticeable effects) on people with fair skin tones.


Melanotan 2 benefits : 

Lasting Tan:Even if dosage is stopped, a warm sun-kissed tan can last for months at a time without

any exposure to the sun.Conversely, tans developed naturally fade in around a months time.

Flexibility of Use:Able to take a small loading dose with continued dosing until desired skin pigmentation

is achieved.Once achieved only need to dose once every couple of weeks to maintain same pigment.

Reduced exposure to sunlight (UV rays):Melanotan still needs exposure to sunlight to be effective.However it will allow the user a significant reduction in time to develop desired tan .



How to use Melanotan II for prosexual effect

Where there is no physical erectile dysfunction and where at least some degree of psychological

libido exists, Melanotan II can greatly increase the tendency to penile erection. The situation can

even become like the years of puberty, where scarcely even the beginning of a sexual thought or

even nothing at all (perhaps an unconscious thought however) produces an erection. General

physical fatigue can become irrelevant. These effects will not occur for all individuals, but do occur

for many.

Prosexual usage requires injection at least about 4-6 hours prior to desired effect. Duration of action

can be about 6-12 hours after onset of effect.

Needed dosage is typically about 1 mg, but for some even 0.5 mg can be effective. As a guide,

dosage should not exceed 2 mg.

Because of the associated effect in increasing tendency to tan, frequency of MT-II use for this purpose

is generally limited. If wishing this effect frequently, a better choice is to use PT-141 (bremelanotide,)

an MT-II derivative.


Melanotan 1 compared with Melanotan 2

Melanotan 1 (also referred to as Afamelanotide) is a synthetic peptide variant of a peptide hormone, called alpha-Melanocyte stimulating hormone or MSH that is naturally produced in the body and is responsible for stimulating melanogenesis, a peptide process for pigmentation of the skin.Alpha-

MSH activates certain melanocortin receptors in the process of exerting its effects.Indeed, MSH

also exerts potent influence over lipid metabolism, appetite, and sexual libido via these melanocortin receptors.As a result, Melanotan-1 sunless skin tanning effects.While Melanotan 2 and PT-141 have been studied at length as a potential remedies for the treatment of sexual dysfunction, Melanotan-1

has been researched extensively for use in protecting against the harmful effects of ultraviolet

radiation from sunlight due to its melanogenesis-stimulating properties.

Both Melanotan-1 and Melanotan 2 are analogs of the peptide hormone alpha-melanocyte stimulating hormone (α -MSH) that tend to induce skin tanning.Unlike Melanotan 1, Melanotan 2 has been shown

to have aphrodisiac properties, the additional effect of increasing libido.Melanotan-1 is a non selective agonist of the melanocortin receptors (MC1R, MC3-5R).As an analogue of α -MSH, its mechanism of action is biomimicry of the natural mammalian tanning process.
