There's a lot of buzz about torem, and it seems to be favored by a lot. I tried it and my bloods didn't look that great, so I went back to nolva. It might have just been me but I was a bit concerned about it not working, however, I seem to be the only one with that concern. Nolva is tried and true.
Bottom line: torem, according to everybody else, is phenomenal; it's like clomid+nolva sans the sides. I'd say try it. I'd love to see bloodwork by somebody using it.
