Nolvadex should be more than enough for e-stane. Since you're running it 6 weeks and potentially at high doses, I like the way it looks. PCT Assist acts as a test booster and hte I3c and Trans-Res work to restore test and manage estrogen, so an additional test booster is not necessary. You could consider adding a cortisol controlling supplement, but personally I do not use them.
Some might argue that Nolva is overkill but based on your post, you seem educated enough to make that decision. Is it enough? Hell yeah...is it overkill? Some might argue yes, depends who you ask.
