Well, clomid makes some people moody. It makes me quick tempered and unhappy at high dosages. I like taking both together, but take lower than usual doses of clomid. If I wasn't so old, I'd probably just go with nolva, but at my age I want to be very thorough with my PCT.
I haven't tried vitrix or trib. I've used longjack and avena sativa during PCT though. longjack didn't seem to do anything, but the avena sativa jacked my libido up pretty quickly.
