Re: Ok, whats going on here?
I'm with Andrew guessing it's the creatine.
It sounds like you are slowly becoming leaner but you didn't notice because of increased water retention that can be caused by some creatine supplements (Chris says it's due to low supplement quality. His company AtLarge nutrition sells a good creatine that true to from I have not really noticed any bloating or water retention with. If you are using some off the shelf mystery creatine you should try his next time).
Are you trying to gain weight? If so, you might not be trying hard enough. Also, how is the mirror check going? Noticed any difference at any time?
