Unexpected weight gain.

Short and sweet with this one boys. I am 2 weeks into my first cycle. All lifts have gone up almost exponentially and I have not noticed a decrease in abdominal definition, however, I am up 10 pounds! As I understand it, the test should barely be having any effect at this point, though I do feel slightly bloated since carbing-up the past 2 days. Is it possible that I have actually gained this much weight without massive amounts of retained water? I know it can't be fat, my diet is clean, though since beginning the cycle, my pro intake has shot up (likely why I am seeing such quick gains so early). I'm not too worried but just thought I'd see if this was highly abnormal or not.

Mostly water weight.

water, expect to lose 10lbs at least when you come off
