clen has been working great for me so far, and i'm on my 12th day of taking it...however i have noticed that my wrists have started to hurt a little more and my right knee was killing me when i went to squat, when before i started clen my joints never hurt. and the bad part is that i am running out of clen, i need some more before spring break comes around. has anyone else ever noticed joint pain on clen or anything?![]()
