high concentration gear hurts am's makes me feel rough. As quester mentioned, could be some contaminates. That a whole lot of juice for a week. You'll regret that one day! I've been there and done it a long time and live with the regret every single day. As long as you run these huge dosed cycles, all I would like to add (other than I wouldn't) is to make sure all of your cycles aren't this high unless it's 1 a year. Most guys run 2 or 3 a year, so I hope you're not running that much that often. Don't think I'm trying to preach at you. I'm only looking out in hopes I can sway others from making the mistakes I have. That's the only good that came from my moronic doses. The hope that I can help others learn from my stupidity! Lol. Good luck to you sir.
