i found some info from Bill Roberts about frontloading SERMs. HIs recommendations are
-300mg of clomid in 6 doses on day 1, dropping down to 50mg a day thereafter
-140mg of nolva in 3 or 4 doses on day 1, dropping down to 20mg a day thereafter
I've decided that's what I'll do. Might be overkill, but I don't see how it could hurt.
