I have noticed more frequent peeing while on AAS, but it could be due to a lot of things. The increased food/liquid intake, increased stress on the liver/kidneys from the drugs themselves, and/or, maybe, the prostate issue mentioned above.
By the way, if you DO get on Cipro, cool off on any heavy lifts - cipro can cause tendon tears - I had to go on it a while back and members on here informed me of the possibilities, and I confirmed the fact from the doctor i was seeing. Be very careful with your lifting. I'd switch to slow, controlled, lower weights for a good 2-4 weeks (at least 1-2 weeks longer than you take cipro, if you do)
