The research team that developed Melanotan II, also called Melanotan 2, MT-II, or MT-2, aimed to create a compound that harnesses the body’s natural tanning mechanism. Their goal was to provide a protective shield and reduce the risk of skin cancer while allowing a deep tan without prolonged sun exposure.
The peptide they developed did more than produce a tan. Melanotan II is a synthetic analogue of α-MSH. It activates melanocortin receptors throughout the body, increasing eumelanin production to create a deep, natural-looking tan without the need for sun exposure.
Melanotan II also has additional effects beyond tanning. Because melanocortin receptors influence several physiological processes, research has shown that Melanotan II can boost libido, suppress appetite, and activate metabolism. Sunless tanning is just one application, but these secondary effects have become a major focus of recent studies.
Melanotan 2 provides a deep, natural-looking tan from the inside out. Researchers have also observed libido and sexual function effects, appetite suppression, and interesting fat-burning potential. The effects of Melanotan 2 are powerful and have immediate quality-of-life implications, which explains its rising interest in research circles.
Research requires high-quality peptides manufactured responsibly, and your studies depend on a source you can trust. CellPeptides is that source. We are a scientific research company based in Switzerland, and our Melanotan 2 is:

Melanotan 2 was developed to replicate the effects of Alpha-Melanocyte-Stimulating Hormone, or α-MSH, the natural peptide responsible for skin pigmentation and tanning. Because natural α-MSH disappears too quickly for research purposes, a longer-lasting version was created.
Melanotan 2 binds to MC1R receptors to boost eumelanin production, producing a deep tan without sun exposure. It also binds to MC3R and MC4R receptors, which are located in the brain, gut, and central nervous system. These receptors are linked to sexual desire, appetite, and metabolism.
This broader activity makes Melanotan 2 valuable for research beyond dermatology. It remains a key tanning agent while offering appetite regulation, potential fat burning, and libido enhancement.
Melanotan 2 research extends far beyond sunless tanning. The peptide has a system-wide effect that depends on dosage. Lower doses mainly influence appetite, while higher doses are studied for tanning and libido.
Melanotan 2 binds to MC1R receptors to boost eumelanin production and create a protective, natural-looking tan. Research includes applications for individuals with fair skin, photosensitivity disorders, or high sun exposure environments.
Melanotan 2 also binds to MC4R receptors in the hypothalamus, which are part of the body’s appetite regulation system. Animal studies show Melanotan 2 can reduce excessive food intake, suggesting potential applications in obesity and metabolic research.
Research indicates that Melanotan 2 increases energy expenditure, helping fat stores burn more efficiently. Appetite suppression and fat-burning effects work together, offering a two-pronged approach in metabolic studies.
MC4 receptors in the hypothalamus are closely linked to sexual desire. Melanotan 2 activation of these receptors has demonstrated libido-boosting effects in studies. These findings also led to the development of PT-141, a targeted peptide for sexual health.
Melanotan 2 is relevant for researchers studying:
CellPeptides provides pharmaceutical-grade Melanotan 2 for labs ready to explore these areas and design new peptide studies.
Melanotan 2 dosing depends on research goals. Lower doses are used for appetite studies, while higher doses are for tanning and libido research. Literature typically cites doses ranging from 0.1 to 2.0 mg per day.
Melanotan 2 is supplied in dry form for stability. To prepare it for research, reconstitute with bacteriostatic water using sterile techniques. Inject the water slowly into the vial, angled along the wall, and swirl until fully dissolved. Avoid shaking. Reconstituted peptide remains stable in the refrigerator at 2 to 8 degrees Celsius for 30 to 60 days.
For precise dosing, researchers can use CellPeptides’ peptide dosage calculator.
What is the half-life of Melanotan 2?
Research shows a half-life of two to three hours, with effects lasting 24 to 48 hours.
Is PT-141 the same as Melanotan 2?
No. PT-141 is a targeted melanocortin peptide derived from Melanotan 2’s libido effects. It does not induce tanning.
Does Melanotan 2 cause freckles?
Yes. Studies show Melanotan 2 darkens all pigmentation, including freckles.
How much bacteriostatic water is needed for 10 mg of Melanotan 2?
Two millilitres provides a lower concentration suitable for many applications. One millilitre creates a more concentrated solution for specific research purposes.
