Wow been doing fina at about 100mg a day for a little over a week now and I am doing leg extensions and after the 4th set I walked around and my legs almost locked up, it felt like they just cramped I am gettting about 2 gallons of water a day, now is it cramping or just some serious mother fuckin pump because I almost have to stop it is pumped so much and cannot even bend down for about 5 minutes then it goes away?
