Okay guys, so I am not running any cycle right now. (I havent actually for 4 years) I am just on a solid diet that is almost perfect right now and taking NO Explode pre-wo, whey protein post-wo with creatine, multivitamins, and lifting 5-6 days per week. So I have noticed over the last couple weeks that the joints in my elbows are really sensative and hurting. I though it was originally from over extending on lateral 90 degree dumbell extensions. But then this last week, and especially after legs last night, my knees are starting to ache as well. I wont to know why this is happening. I mean, my supplement intake is really shallow right now so I dont know if it is the N.O.? Or is there something I can take to counter this? I figured I would ask for advice before I started searching the web for joint products. Thanks guys!
