I understand, I'm as puzzled as you are and if you said that I would think "he's full of shit" however I KNOW its not fat. If its water then its inside the muscle cells and i stopped creatine a week ago to make sure that wasn't it. Maybe it because I lost 15lbs post cycle on my last cycle. I don't know bro, I can't explain it but my strength is through the roof and my size is noticably different. What it is???? I know that 3 scales are not lying to me. Maybe its not muscle but if its not then it sure looks like it because my arms, legs, chest, shoulder ...in fact whole body looks bigger muscularly.
No hard feeling bro, sorry if I snapped at you.
