to me or the "committee" in my head? (joking) i post here while i'm at work and in a rush sometimes....ok when i come off a cycle, lets say an SD cycle (for example) my natural test is most likely shut down (or suppressed) my estrogen levels are high due to the fact that my body thinks it has a lot of test there (which is BS, cause it's just the SD, correct?) so when i come off cycle and into PCT my natural test is in the toilet (which that needs to be brought up ASAP, to keep my gains) and my estro really doesn't need to be that high (so lowering that is a good idea, LOWERING IT not killing it entirely). i have heard that when you come off cycle, there is some "good" estro that you still want to have around? now introducing a SERM (which i always do) in layman's terms, puts a coating around the estro causing no binding to the receptor, keeping it "alive" but pretty much nonfunctional, for the most part. so if my SERM is doing all that, then adding an AI to the mix would seem, stupid. Over kill, no? so what i was looking for, is a creditable source, Doctors or scientist's studies of test and estro levels being monitored, ie if someone was to take blood and so on after i just finished a cycle, to see where my test levels and all other levels are at. there is a lot of talk about levels being here and there since i became a member here, and kind of want to know a bit more about this, because so far (for me) it's only been "here-say", you know, one person repeating what they were told, which is fine...if the first person to start it had good info. i'm, not saying any of this is wrong or right, but that's my point, i don't really know where this info came from originally. make sense? if not,i have to involve the "commitee"...:thumbsup:
