Ok this is just my opinion but if this is your first cycle then 10 weeks is a good one. No harm in lengthening to 12 though. 12 weeks just gives you more time to grow. I am a believer in longer cycles. Not nessesarily biger cycles just longer in duration. I think 16 weeks is good. My next xyxle is going to be 6 months. Its really all preference. If its your first then you may want to stop at ten so you have something to compare a longer cycle to.
I would bump the anavar 2 weeks past your end date for the EQ and Sust. Those are both long acting esters.
