In the past 10mg nolva a day once the nips got sensitive if they did was the way to go. I feel that accidentally crashing your estrogen is by far the worse of the two situations. Now if you can dial in your estrogen and can get it tested on cycle then an AI keeping estrogen levels around 30-40 would be ideal. Most people can't nail that down as well as that to be honest.
So in the sake of ease of use and avoiding the pitfalls of low estrogen I would recommend a SERM
IF NEEDED.
Right now I am doing the 30mg of Torem that
Spurfy suggested with that 40mg of Var and it is treating me nicely. I am on TRT so not sure the SERM will do much but I had it at the house and Spurfy said to run it even though I was on TRT. So we are going to see how that works out. I did notice my semen volume seems to have increased slightly. Not much else going on. Definitely no signs of gyno but I dropped my Test E to 100-120 a week. So there really shouldn't even be any elevated estrogen anyway.
When i ran 200 test e, and 400 EQ I didn't need an AI, so I did not run one. Any time you don't have to mess with estrogen levels or a SERM leave them alone... that is my stance. However if you need to use both to get control of something then I would use both. If you want to starve Gyno to temporarily shrink it up some use both...
