Does fina cause insane muscle pumps? I didn't know if it was from the test or not, but im doing preacher curls and my biceps expoded with the most painful pump of my life. Im laying there trying to strech it out trying not look to dumb because i have tears in my eyes and then my lower back starts getting pumped up from my trying to strech my biceps. Just wondering if anyone went through this, my forearms are getting pumped from just typing this,annoying...i cant even rub one out without my shoulder and arms getting all jacked up..WTF!!!
