Just went to GNC to buy some xenadrine w/ephedra (i've taken it in the past - before starting atkins) and the guy said they're not making it any more. But he recommended "Stacker 2" and it contains ephedra. You're supposed to take 1 of these yellow pills after a meal......I'm a little nervous about taking them... Anyone ever try them? 1 capsule has 25 mg ephedra. I dont remember whether xenadrine had more or less.
