Ok I’ve been reading and seeing a lot of people leaving Clomid out of their PCT.
We’ll let me tell you Clomid is what gets your testis working again. How you ask well I’m about to show you.. YES you need both Clomid and Nova to make your PCT. However, Clomid is the most important. Here is why.

How your testis make natural testosterone.
(REMEBRER TESTOSTERONE DOES TRUN INTO ESTROGEN THAT’S WHY WE TAKE AI's)

Leyding cells(your testis)---->make Natural Test------>(some turns into estrogen)-------------->pituitary Gland(Makes LH)----LH goes to------>Leyding cells(testis)make Natural Test--------and the process starts again...

If you have too much estrogen well now there will be too much estrogen hitting pituitary so the pituitary cannot make LH—no LH than your Testis can’t make test..Which is what happens after Cycle.

How Clomid works during PCT when your Testis can’t do shit.

Leyding cells(your testis)---->make Natural Test(some turns into estrogen)---which isn’t happing cause they are shut down and LH is not hitting your testis----------->Clomid blocks estrogen from hitting the pituitary(now the pituitary can make LH)---->pituitary Gland(Makes LH)----LH goes to------>Leyding cells makes Natural Test(your testis start to come alive)--------and the process starts again the correct way..because Clomid it blocking estro and your testis are coming back online.

Hope this helps to understand how Clomid works.
