Liquid Var Help

First cycle, following Austinite's incredible guide.

Exactly cookie cutter from the first cycle sticky.

I know it's not recommended to add anything extra into your first cycle but so far everything is going great & I just got some liquid var. I'm definitely interested in incorporating this into the 2nd half of my cycle and was wondering which of the following would be a better way to do this:

Weeks 6-12 - 75mg per day (6 weeks)

Weeks 5-12 - 60mg per day (7 weeks)

weeks 4-12 - 50mg per day (8 weeks)

Thanks for the feedback. BTW this spam software owned me like 8x in a row trying to post this.
