Melanotan 2 – Research peptide for skin pigmentation and tanning

Melanotan II (MT2) is a synthetic peptide used in laboratory research to better understand the processes behind skin pigmentation , melanin production , and tanning . MT2 is known for its ability to stimulate the skin's natural production of melanin—the pigment that creates a tan and protects against UV damage. Researchers often study the effects of Melanotan II compared to Melanotan I (MT1) to investigate differences in efficacy, receptor activity, and duration of skin tanning.

Benefits of Melanotan II

• Research into skin pigmentation and tanning without direct UV exposure
• Stimulates melanin production in laboratory studies
• Interesting for studies on protection against UV damage
• Is examined in combination with tanning bed and UV research
• Popular research peptide for anti-aging and skin rejuvenation
• MT2 is faster and more powerful in operation than MT1
• Suitable for measuring how pigmentation is biologically regulated

How does Melanotan II work?

In laboratory studies, Melanotan II works by binding to melanocortin receptors (primarily MC1R and MC3R) . This binding stimulates the production of melanin , the natural pigment that darkens skin. Compared to Melanotan I, which primarily targets the MC1R receptor, Melanotan II has a broader range of effects. Because of this, it is often studied as a more potent alternative in research on tanning, hormonal regulation , and energy metabolism .

Melanotan II is therefore not only interesting for pigmentation research, but also for studies of sexual function , energy consumption , and receptor mechanisms . In research models, MT2 also appears to have a faster effect than MT1, making it a popular choice in experimental studies of sunless tanning and skin protection against UV stress.

Preparation and storage

Melanotan II is usually supplied in freeze-dried (lyophilized) form. For laboratory testing, it should be dissolved in a suitable solvent, such as bacteriostatic water.
The peptide should be stored between 2°C and 8°C to maintain maximum stability and quality. Avoid prolonged exposure to light and heat to protect the peptide's structure.

Purity and quality

Each batch of Melanotan II comes with a COA (Certificate of Analysis) confirming the purity, identity, and stability of the product. Most high-quality suppliers guarantee a purity of at least 99% , which is essential for reliable research results. These quality reports demonstrate that the peptide meets international research standards.
