Bro you will get a lot of mixed opinions on VPX.
Since you already have it, with you stats I would probably do 3 ml
3x a day.
Stacking 1-AD would be of no benefit, since it converts to 1-test in the body.
Just my opinion but you can make 100 ml of 1-test cypionate, with the optimal delivery method

for a lot less than the VPX products.
And yes you will probably need some form of PCT.
