Agree that checking kidney function is important before macro-dosing creatine.

I used to be a skeptic, but have come around after reading about it more. 
Only caveat is I would highly recommend doing both renal function and urinalysis (looking for microalbuminuria) before starting. If any family history of early primary kidney disease, I wouldn’t start in my pt. Otherwise it’s great.
