i hate to ask, but..

I tried this, my E got up to 87 without an AI.

300 TestCyp/400 Mast per wk, 10mg nolva daily. With SENSITIVE estrodiol of 87 and total testosterone of ‘only’ 1275. How high is too high before you use an AI?

its really person dependent.. with the Masteon in there plus the Nolva. I'm guessing you had very little negative estrogen sides even though blood levels were high (the estrogen receptors in the negative areas we want blocked, like breast tissue and fat tissue, were bound up and estrogen had no effect on them .. thats a good thing. where as the estrogen receptors we don't want blocked, like in the liver and muscle tissue, were benefiting from the elevated e).. however that number is pretty high on only 300mg of test. do you know what your 'free test' numbers were on that test

Yeah that's true, I was shocked at the number, but I really wasn't feeling bad at all. Admittedly, I've always kept my E in check, so I'm not sure I really know what high E feels like.

Unfortunately no, I only got Total test that time, no SHBG or anything. How would knowing my 'free test' be helpful? I have 'free test' values from random other cycles, but I don't get it every time.

thats what I like about SERMS ('selective' estrogen receptor modulators) . its 'selectively' blocking estrogen effects and not all E effects nor lowering blood levels of E like an AI would . lots of benefits here. one being the more E you have in the blood stream available to pass through the liver , the more the liver is able to produce HDL cholesterol (one reason why an AI lowers 'good' cholesterol and a serm does not).
and also the elevated IGF levels and anabolic effects higher blood levels of E have on muscle tissue.
so you were getting benefits out of the higher E levels, while blocking some of the negative traits . thats probably why you felt just fine

I was curious how much the Masteron may of been playing a part here, as it lowers SHBG and will then help raise free test levels. basically, Masteron can turn your 300mg of test your running and make it seem to work more like your running 400-500mg
