Some good info in the link but some some off base.
Nolva/Clomid are not extremely liver Toxic. Remember guys these drugs were not meant fro AAS's users, Woman take these for YEARS. I am not sure if he mentioned the positive effects of Nolva on lipid profile.
That said, I personally did not use Nolva for a 3 week SD cycle, just Rebound, Lean XT, and other support supps. I didn't do post cycle bloodwork to check my lipid profile but I feel a 3 week cycle of SD will not greatly effect Cholesterol and is easy enough to return to normal limits with support supps. I kept Nolva handy in case of Gyno, which ATD is not even remotely close to Nolva in treatment.
Although SERM's may not be completely necessary for PCT of all AAS, I cannot think of any reason not to have it on-hand.
