The only comparison i know of was no estrogen compared to having estrogen .
So of course having estrogen is good but having higher then normal estrogen is not proven to build more muscle its a female hormone .
Most people who praise estrogen and post some pics i see they have gyno , high prolactin Ed, but tell you they are fine and have no side effects its strange really.
I bought in to this bullshit myself reading online and hearing it on Youtube ….
And let me tell you the worst side effects i ever got from using steroids is when i stoped taking an ai!
The thing is its not a sudden change it happens gradually its so slow its hard to notice… but depression happens with high E.
Add a limp dick , acne and gyno to it and your set brother .
So don't be afraid to take an ai, don't be afraid to experiment.
So what if your estrogen get to low? Its not a life sentence you just take more testosterone , or some Dbol , dhea or even ment ….. and its back to normal.
Crashed estrogen does not just happen it gets low first and you feel it so you can test for it and adjust .
If you happen to not need an ai great more power to you , one less thing to worry about.
All the horror crashed estrogen stories com from TRT guys that where over prescribed ai and stuck to that protocol for to long as they did not understand what was going on.
But back to topic your protocol looks fine dont start the ai till 2 weeks in and do bloods week 4 or 5 and re evaluate based on results and how you feel.
