Anastrozole, or adex, is an AI, which will control the conversion of test to estrogen. Post cycle, you want to use a SERM, clomid or Nolvadex. I have been leaning more toward Clomid, starting 2 wks after your last shot, using 100mg ED for 1 wk. Then 50mg ED for 2 more wks. 3 wks total. Prov will help some with estrogen control on cycle and will bind with SHBG, making your test a little more effective, but if you use it or not, your gains will probably look the same. It isn't going to make or break you. You might look a little harder with prov on cycle and it will increase libido. I would not use it as your PCT though.
