I by no means have enough personal experience under my belt to give anyone advice, so all I'll say is that I plan to use Tenny's PCT plan, with some low dose Aromasin to further control estradiol.
I have read a lot of threads where people used aromasin along side nolva, with good results. Plus, if you're one of the people that flood your system with HCG the week before you start PCT, aromasin will help.
Hopefully one of the gurus will chime in on this.
