I would use real Nolvadex as PCT (it is a SERM) rather than GASPARI NOVEDEX XT an (AI)
Nolvadex is cheap and even on the black market it is half the price of NOVADEX XT.
When you come of a cycle you have no artificial testerone in your body and your own levels are low or non existent, but you have lots of estrogen.
As a mans body makes Estrogen by Aramatising it from Testerone your body uses the levels of Estrogen to monitor how much testerone to make, if the estrogen levels are high it makes less testerone and if they are low it makes more testerone.
After a cycle all of this is out of sink with high Estrogen levels, your testicles not working and your body not wanting to switch them on because your Estrogen levels are high.
It is not much good taking an AI ( aramotise inhibitor) as there is NO TESTERONE IN YOUR BODY TO CONVERT.
A SERM is different and blocks Estrogen at the receptor site.
Forcing your body to switch on your testicles again
Always go with a SERM.
