im about to begin a t1-pro cycle in a month or so... is 6-oxo good to use for the post or should i use nolva or clomid?

How long is the planned cycle? 6-oxo is good but clomid or nolva would certainly be better....
i used 6-oxo on my last cycle of normal dosing with t-1 pro.
600mg 1 week
400mg 2 weeks
300mg 1 week
worked ok but i would lean twards getting nolva cause it's cheaper and probably more effective. that's what im doing for my upcomming cycle.
