Test E PCT question

OK .. I'm in week 6 right now of my cycle ...

500mg Test E / week (in 2 - 250mg shots / week)

I've hate moderate success with this cycle so far ... but i'm just hitting the mid of week 6 now so I understand I should hit highs soon.

My question is regarding PCT tho ... what kind of PCT should be done for a Test E only cycle specifically ... I've have no acne, no water retention .. etc yet ... and am wondering what the best combo is

Nolva
Nolva / Clomid
Nolva / Trib

or Clomid only since I'm not having water retention of any other aromatizing side effects yet.

Nolva, clomid, trib and an AI is what I would recommend. Some will say that it is going overboard but why not cover all the bases? At least use nolva and clomid though.
