As Fish44 stated Human Chorionic Gonadotropin (HCG) would be for on cycle.
I'm hesititant to answer your other questions, as I'm more interested in how you've been a member since 2011 and haven't picked up on those answers. At any rate Nolva and Clomid is a good combo for post cycle therapy (pct). The Human Chorionic Gonadotropin (HCG) can be ran at the dose given to you above by Fish everyday up to 4 days before your serm(2) treatment (PCT). Nolva can be at 40/40/40/40, Clomid can be at 50/50/50/50.
