PCT looks like this: (Anthony Robert’s)

Week Nolvadex HCG Aromasin Vitamin E
1 20mgs/day 500iu/day 20-25mgs/day 1000iu/day
2 20mgs/day 500iu/day 20-25mgs/day 1000iu/day
3 20mgs/day 500iu/day 20-25mgs/day 1000iu/day
4 20mgs/day 20-25mgs/day
5 20mgs/day 20-25mgs/day
6 20mgs/day

I am wondering if I can drop the aromasin from it, is it necessary? If I drop it do I need to replace it with anything else? Or do you think it is an important part to my pct? My cycle is:

Wk 1-4 Dbol 30 mgs ED
Wk 1-13 Test E 500 mgs/week
Wk 1-12 Equipoise at 400 mgs/week
Wk 10-15 Winny 50 mgs ED
Thanks.
