Cycle would be 10weeks of 500mgs of sust. I know pct is a combo of nolvadex and clomid but my question is what to take while on the cycle. Below are the options I've read, any suggestions?

A)Nolvadex (10-20mgs) every day
B)Nolvadex (10-20mgs) every day & Aromasin .25mg every day
C)Aromasin .25 every day

Which option is best and while on cycle?
