Hi, this is my first post. I have been using this product called Melanotan which offer sun protection, libidoe enhansement and fat burning in addition to giving you a pretty descent tan. After using this stuff for a few months I can honestly say this stuff gives you a pretty good colour. Once you have loaded you only need a small amount for maintenance. Probably worth increasing dosage for any event you want to increase your colour for or as a way to cope with hotter weather. While not yet FDA approved this will eventually go to the mass market in some form.
