Before a cycle..about 4 to 5 weeks in..and post cycle..
To get a baseline before..if the Test levels are not normal range..during the cycle to see what's doing what..and after everything has cleared, after coming Off..
Also,you what to know about Estrogen..
That's how you know if you need an AI..
TIP....
Some compounds have AI qualities..like EQ,Primo,..damn it's late, I can't remember them all..and Proviron..
Lots of experienced guys prefer to run said compounds instead of dedicated AI's..due to sides..
The Only Way to really know what works for you...is to run Test only with said compounds and bloodwork ...
It's a slow process..but the pay off is nice down the road..
Remember it's not a race..or the destination..rather the Journey..
Enjoy the Ride..!!
