I was benching today and one of the GYM trainers told asked me if I felt allright, because he noticed that under my armpits were yellow colored. I asked him why this may be and he said, Jaundice. I have been taking Xenadrine for about a year now (on an off, 4 tabs a day) along with GNC multi and DHEA. All of my friends keep telling me that I need to stop taking it, because it will eventually "kill me" but so far I have lost about 70 pounds and am to supersticous to deviate from my daily routine. I run around the track usually about 5 times a week anywhere from 2 to 5 miles, and do upper boddy every other day. Recently I have not been getting sufficient amounts of sleep because of school, so am wondering maybe this could be the culprit. My question is, can anybody offer some honest input on whether or not Xenadrine (RFA-1 the original with ephedrine) is dangerous to ones liver. I dont get headaches, or the shakes, as in my previous "obese" lifetime, I was a caffene junkie, so to this day it really has no effect on me. Other then that I just know I have lost a shit load of weight through taking it, and its now a placebo whereas I don't want to run or work out without taking it.
