I have no opinions on either Prop or Test E. Only difference is the water retention being more on test E, but less frequent Injections. As for the Vars, you noted that you'll start from week 5 - 12 or 13. I personally would not start it off so early in the cycle simply because I think it is effective for the first 6 weeks, after which the effects become less profound. So, assuming you're using Test E, you'll probably gain most (not in terms of weight, but lean muscle mass and strength) on week 4-6. Starting on week 5 is kind of a waste IMO. Better to start off at week 8-14 (or 2-3weeks after your last shot of Test E). Basically, when the effects of Test E peaks out and when it starts to plateau, you throw in the Vars to bring on another spurt of growth. So you'll be growing from week 3-4 non stop until almost towards the end of your cycle.
