Nolvadex for an anti-e during cycle isn’t very effective due to the way it works, it’s not an aromatase inhibitor like aromasin is. You need to run aromasin about 12.5mgs EOD, and see where your estrogen levels are when you get mid-cycle bloods done. You can adjust from there if needed. Also for PCT I would run both clomid and nolva at 50/50/25/25/12.5 and 40/40/20/20/10. You could just do four weeks I prefer to go a little longer. Also a good OTC test booster will help get your body back on track.
