I had to sign up just to go way back and reply to this. Yea I have done it about a week and a half only. Did the first week with 20mg dosages a day (like alot said.) Now its tapered to only 5 or less. I worked out a while back and am just restarting up in the last month or so. And yea the first few weeks with out it I had no pain. But with it I started to also go up in weight pretty fast. And my elbows and everything in that area really started to hurt. But only during pulling. Ala curls or pull down or whatever. I hate spending a tun on supplements, so I don't know about getting something to help the joints, If I stay on creatine. Its almost like tennis elbow. Which I id used to get when throwing a football in HS. But never during a workout. I wanna stay with it, because it works pretty well. No miracle worker, you still have to bust butt. But it does work, at the least when your on it.
