IMO, front load the 1st wk too.
I'm not convinced about running nolva at such a high dose for a week, it's a moderate dose medium length cycle.
My choice for an adequate PCT for this cycle would be
Clomid 100/50/50/50.
Nolva 40/20/20/20
Hcg if your nuts shrivel up too much could be used for the last 2wks @ 500iu twice wk.
