Re: question for my gf?
Like most thermogenics, it is safe. Although i would suggest she take the warning on the side of the bottle seriously.
I would also start w/ the lowest dosage and increase it accordingly, as directed.
Also, i would cycle it in and out. take for say 4 days and off for 2-3 days. That way your body does not become too accustom to having it in it's system. It will work better for her this way and she won't rely solely on it to help her burn fat and give her that added boost.
Above all, without good nutrition and an exercise program, this will be a short lived solution to fat loss for her in the end.
