Opinions vary, but after being in this game for over 30 years I've come to the conclusion that it's HMG, UNLEASHED, POST CYCLE, arimidex and Alpha Sustain.
Some people have other preferences but that combo always works. (Unless of course, you've completely obliterated your HPTA in which case NOTHING will work).
Firstly to ensure the best possible recovery run low dose HCG on cycle (250iu's twice weekly is generally sufficient) and then Nolva for PCT at no more than 20mgs/day and for 4 weeks duration in combination with PP's Test Recovery Stack.
