Melanotan is a cosmetic product that increases the production of melanin in the body. Melanin is a brown pigment that causes the skin to become darker when exposed to ultra violet rays; it is the main factor in determining skin color. Taken in injection form, Melanotan causes the user to build a gradual tan without spending hours in the sun. According to Melanotan Europe, Melanotan is especially useful for fair-skinned people who burn in the sun rather than tan. Storage of Melanotan is a relatively simple process.

Store powder (unmixed) vials of Melanotan in sealed plastic bags or containers in your refrigerator. Temperature should be between 36 to 46 degrees Fahrenheit, and make sure to keep the vials away from food products. Powder vials stored at this temperature will remain viable for up to 12 months, according to Melanotan Europe.

Store mixed (reconstituted) vials of Melanotan in your refrigerator as well. As with unmixed vials, keep these vials in sealed plastic bags/containers and away from food. Use mixed vials within an eight-week period as the Melanotan degrades after this allotted time. It is still safe to use after eight weeks but it will not be as potent.

Store unmixed vials of Melanotan in the freezer for up to 24 months. If using the Melanotan within 12 months, simply keep the vials in the refrigerator, according to Melanotan Europe as freezing and thawing vials can damage the Melanotan II peptide.


Never shake vials of Melanotan.

Do not use Melanotan as a replacement for sunscreen as it does not reduce UV damage.


Do not pre-load and freeze Melanotan syringes. When peptide freezes, it can potentially come out of the solution into particles, according to Melanotan Europe, and may not return to the solution when thawed. This can result in particles being directly injected into your skin, which can cause damage or irritation at the injection site.
