Nolva is not good for PCT...it does not always illicit an LH response, however, if no progestins were used, there may be some utility in using it for a short period with clomid (it is estrogenic at the pituitary level but antiestrogenic at the testes, albeit less so compared to AIs). Its not recommended for use in cycles or PCT if progestins were used. It is a gyno promoter in this situation via the progesterone receptor. It also lowers IGF. It destroys HDL and kills libido in most guys. It is also adipogenic. It does antagonize the E2 receptor in breast tissue so it can be effective in managing existing gyno...but letro works great as well. Generally speaking, AIs are a better choice for estrogen control...PCT included. Clomid(illicits LH response) + AI for PCT. Nolva will cause estrogen rebound...even at low doses. Clomid can, but not at the doses used for PCT.
