I would recommend Aromasin over Proviron...
And you shouldnt use Adex in PCT as Adex and Nolva reduce each others effectivness.
I agree with Mercy Dog. I would stay away from blended tests. Stick to a single ester test.
Also why are you bumping the dose up to 750mgs a WEEK?
Heres the PCT i would do.
Nolva - 20/20/20/20
Aromasin - 25/25/25/25
Clomid - 25/25/25/25 (Clomid is optional if you have Aromasin.)
No Adex, or Letro for PCT EVER!
