Ok, ephedrine. I ve put in a lot of work and money attempting to locate a product that gives me the drive the Ephedrine used to. Ephedra cramps my tummy, heavy caffine gives me a head ache. Ive heard that Vapor Xt is outstanding. Anyone out there able to shed some light on this product or have a better product that I can start using Like the old Ephedrine based products that used to line the shelves? Im only interested in losing fat and maintaining my current muscle mass.
