test and finastride

ok guys Im going to be running a cycle with test in it the cycle looks like this

1-3 test prop 100mg eod
1-10 test enth 500mg
winny 9-12 50mg ed
arimidex .50mg eod

now I read an article about how much safer it is to run finastride with test to prevent prostate problems. The question I have is how much to take throughout the cycle and does it have any negative effects by taking it. I figured the man sells it so cheap why not take it I mean if it can prevent prostate cancer then Im all for it.
