Omega, im not buying that nolva is superior. After all, nolva and clomid affect the system very similarly (ie they block estrogen receptors). Now I do believe that post cycle clomid use is a bandaid, but one of the main reasons recovery is slow is because the teste's have no been producing sperm or test. So while I do believe there is a bit of truth to haveing a crash after ending clomid, the crash is short and the body should kick in a hell of a lot faster since the teste's have been responding to the LH/FSH that the system has been fooled into producing.
On a side note, nolva greatly reduces igf-1 levels whereas clomid does not seem to adversly affect them to the same degree. Just because of that alone I would chose clomid over nolva any day.
