I started my pct yesterday with 50 clom. & 25 nolv. I have been off my cycle for going on 4 wks now. I haven't lost a thing that I gained, even put on a few lbs. Last time I did my pct, that was when I starting the decline of strenght and size. So do I need the pct? And will the clom and nolv cause lose of size and strenght?
