Its not about eliminating estrogen. That is a bad thing. Its about balancing it. You need a testosterone to estrogen ration. Without Estrogen you will notice things like Achy joints and low libido. Keep in mind if you crush it now it will rebound on you which could give you gyno symptoms or even surpass your current number it was at. Daily control of it through the use of an estrogen blocker and then re testing will be necessary in 4 weeks to make sure you have it under control. Letrozel will crush it but like I said that is not necessarily a good thing looking several weeks out. Arimidex works well but keep in mind it is bad on your good cholesterol so use something to support that. Exemestane is a great product for lowering estrogen and not as many risks as Letro or Arimidex. If you are not being RX'd Exemestane (im for getting its brand name) you never know what you are actually getting so keep that in mind. If the dose is off or the actual chemical is not Exemestane it could be little to no benefit to you. i would not even play with Research Chemicals at this point. You are in a dangerouse situation and you want to be sure you nip it in the bud immediately. Finally, just because you got it under control in 4 weeks when you re test does not mean you can stop using an AI. I would do a few test to make sure you have tour E levels in the range they need to be in and then stick with the protocol once you know its dialed in. High estrogen puts you at an increase risk of Heart Disease, Tyep II Diabetes, water retention, increased blood pressure etc. if you have any other questions please feel free to PM me if youd like. Good luck
