Buy Melanotan 2 Peptide (α-melanocyte-stimulating hormone). Also known as Melanotan II

Melanotan 2 is a synthetic analogue of the peptide hormone α-melanocyte-stimulating hormone (α-MSH), which belongs to the melanocortin peptide group. These melanocortin peptides are natural hormones involved with pigmentation, energy homeostasis, sexual functioning, the immune system, inflammation, and the cardiovascular system. Melanotan 2 non-selectively mimics the action of melanocortin peptides.

Melanotan 2 acts as a non-selective agonist of the melanocortin receptors type MC1, MC3, MC4, and MC5. To the extent that Melanotan 2 produces melanogenesis, this is thought to be caused by activation of the MC1 receptor, whereas its clinically documented sexual effects are thought to be related to its ability to activate the MC4 receptor (though the MC3 is thought to possibly also be involved). Increased melanin production helps protect the hypodermis, which is the layer under the skin from the UV-B light that causes damage. It works by absorbing UV-B light, which blocks its passage into the skin layer.

Clinical trials have shown the molecule significantly promotes natural melanogenesis. Related increased melanin production promotes faster and stronger tanning of the skin exposed to ultraviolet radiation from sun, and simultaneously improves its natural resistance before sunburn. With this way the molecule may  help to protect skin against the harmful effects of UV rays and prevent skin cancer. It may also significantly increases libido and sexual activity and suppresses hunger.

Melanotan 2 chemical structure


Melanin is a dark pigment primarily responsible for skin color. Functionally, melanin serves as protection against UV radiation. Melanin is produced through a process called melanogenesis by Melanocytes – melanin-producing neural crest-derived cells located in the bottom layer (the stratum basale) of the skin’s epidermis, the middle layer of the eye (the uvea), the inner ear, vaginal epithelium, meninges, bones, and heart. Typically, between 1000 and 2000 melanocytes are found per square millimeter of skin or approximately 5% to 10% of the cells in the basal layer of epidermis. Although their size can vary, melanocytes are typically 7 μm in length. Once synthesized, melanin is contained in special organelles called melanosomes which can be transported to nearby keratinocytes to induce pigmentation. Melanocytes also have a role in the immune system.

Peptides Prefer the Cold

Keep peptide vials refrigerated at all times to reduce peptide bond breakdown. DO NOT FREEZE. Most peptides, especially shorter ones, can be preserved for weeks if careful.

Always swab the top of the vial with an alcohol wipe, rubbing alcohol or 95% ethanol before use.

Before drawing solution from any dissolved peptide vial, fill the pin with air to the same measurement you will be filling with solution, ie. if you plan to take 0.1 ml, first fill the pin with 0.1ml of air, push the air into the vial, and then draw the peptide back up to the 0.1 ml marker. Doing so will maintain even pressure in the vial. Always remember to remove air bubbles from the pin by flicking it gently, needle side up, and pushing bubbles out. In addition, push out a tiny amount of solution to ensure there is no air left in the metal tip.


Only Mix With Sterile Bacteriostatic Water

The purity and sterility of bacteriostatic water are essential to prevent contamination and to preserve the shelf-life of dissolved peptides.

Push the pin through the rubber stopper at a slight angle, so that you inject the bacteriostatic water toward the inside wall of the vial, not directly onto the powder.

Lyophilized peptide should be stored at -20°C (freezer), and the reconstituted peptide solution at 4°C (refrigerated). Do not freeze once reconstituted.


Do Not Shake Vial To Mix

Air bubbles are unfavorable to the stability of proteins.
