 my first two cycles I did not run any anti-estrogen
 I managed to get away with it to some degree but I also had a lot of excess water retention and bloat 
This time i want to try doing 1000mgs testosterone and 1000mgs primobolan 
What is the length of cycle i should do this time?  
And should i try no AI again?
