Yes for sue it is safe. It is a safer version of Clen and Ephedrine. I do work out hard almost every day. But there are a lot of us that would like the helping hand of a supplement. I take a multi Vit every day because I really do not want to sit down every day and pick out all the food it would take to equal one multi vit. This supplement is just to help out with mussel gain and fat loss. But when they took Ephedrine out of the supplements I found that they just did not work any more. But this is the new and improved way of doing it.

Just my opinion
