Sorry for the late reply, but I did have to jump in really quick.
I did creatine on a cycle once and ran into what might have been a "serious" issue and will not do it again. This was about 8 or 10 years ago, when creatine was like the somewhat "new and great" thing to get. I actually ordered from a bulk distibutor, I think the company was JBN (just be natuaral) and I have no clue if they are around anymore. They sold all kinds of name brand products, but I bought their own brand. Again, this was a long ago, but I do remember their dosage said something like 25mgs 3 times a day. When I look at the dosages now a days on labels I see they are MUCH different, so that could be what the problem was. Anyway, I was taking anadrol with my cycle and within about 30 minutes after my first dose of creatine I had to piss and it felt a little funny.... then I had to piss again about 15 minutes later... then again, and again... this lasted a few hours. Then the next day I repeated the process and the same thing happened. I mean it, I was pissing about 6 times an hour and thought the lower right side of my back was hurting internally.
I never got any of this checked out, and again it was a long time ago. One thing for sure though is that it REALLY, REALLY scared the crap out of me!
I could be wrong on this so you can make fun of me like crazy, but I believe most labels list about 5 or 10 mgs of creatine now a days??? Is this correct??? If it is, and considering a few others posted they do it then I would..... my only suggestion would be to stick to the label. I think since the product was somewhat new when I got it that no one was really quite sure how much you can/should take, plus the fact that back then they were saying creatine is not harmful at all. I was forced to take a couple years off between then and now and I did not really read much, so maybe there was some big article somewhere about dosages and the like. If there is I would like to read it, because I mean it, I WAS SCARED and personally will never take creatine on a cycle again if orals are involved.
