Time on=Time off. In your case, do you actually think the Kidney infection was from your AS usage?
where you drinking plenty of water?
I see alot of guys that develop symptoms or some type of illness and immediatley want to blame AS for this, when it may have not been the case. In other words, you may have gotten that infection if you were off AS.
Are you drinking enough water? Are you drinking soda's?
What is your diet like?
Could your doc give you any insight on what caused it?
