Anadrol stack with Test Pro

I have been reading about anadrol and out of the orals it sounds like it is the best. I have heard good things about it. My question is how long does it stay in your system? A friend of mine told me it stays for like 3 months, but I think he is wrong.
Also would a stack of Test Pro for 12 weeks and 4 weeks of Anadrol be good?
Or is that running the Test for too long?

age
height
weight
bf%
diet summary/# meals per day
years lifting / workout split
cycle experience
pct/estrogen control knowledge
goals (size/cut/strength/speed etc...)

its a good cycle bro
in your system for steroid drug tests?
