I'm Currently on Testrogrow 2HP and about done with my first cycle. It says to go 21 days on then 3-4 weeks off, which I think 21 days is a little short so I'm thinking of extending it. Anyways! my real question is should I be on some sort of estrogen blocker after I get off the T2HP?? If so, doesn't anyone have any supps that have good reviews or where I would look to find them?? Thanks for any info you could provide.
