I have started taking endothil for about 3 weeks now, does any one else use it, or have used it? my results have been great so far, even though i have kinda eased up on the necessary work outs. right away the first time i used it, on biceps, i felt this rush of something through my biceps and the next day my left bicep would not stop twitching. lol. also for a while i have been working on my abs, and since i have been using endothil w/ my ab work out (25 lbs w/ the crunch movements on the bench like thing)., they're even more visible now. let me know wht experience you all have had with it and even tips. thnks.
