Clomiphene(clomid)--works by blocking estrogen at the pituitary. The pituitary sees less estrogen, and makes more LH. More LH means that the Leydig cells in the testis make more testosterone.
When your on Cycle the pituitary thinks your testis are making enough TEST and the LH falls off and the pituitary turns off..
You need to understand that there are two places your body makes LH one is the pituitary the other is the is your testis, which makes both luteinizing hormone (LH) (for natural test conversion, and FSH sperm count and motility)
How does Clomid really work---well you need to understand that in your testis, better yet the Leydig cell is where Testosterone is made. From the conversion of LH. See LH is what your testis use to make Natural test.
But why is Clomid so important in a PCT. Well Clomid, not only blocks estrogen at the pituitary so the pituitary can make more LH--BUT THE PITUITARY ALSO CONTROLS THE MAKING OF TESTOSTERONE IN THE TESTIS So if your pituitary is not functioning correctly your recover time will take longer during a PCT.
Always use Clomid in your PCT...
My little graph how test is made..lol
Normal..
pituitary---->LH------>Leydig cells---->test----little estor(guys need it to)---back to the pituitary and the process starts again
On cycle
pituitary---->LH------>Leydig cells---->Doesnt make test cause your body has enough pituitary shuts down.
Off cycle with clomid
Clomid blocks Estor from the pituitary---->LH------>Leydig cells---->test---->Clomid blocks Estor----Pituitary makes even more LH---and continues while on PCT--so every week your Pituitary makes even more LH when taking clomid, and will tell the testis MAKE MORE NATURAL TEST!!!!!
Hope this helps.
