And with the recepters blocked it lowers estrogen. Holy shi* are you serious?
No it doesn't
It lowers estrogens effects but not the estrogen itself, and note specifically its selective as to what type of receptor it effects and the breast tissue is definitely dense in this type of estrogen although not the only place in the body.....
An ai literally erases the possibility of estrogen n being made in a male body by preventing Testosterone from converting into estrogen.
Since coming into pct your test levels will naturally be low and est high in comparison it is VERY wise to use both a SERM and an AI. The way you use then is important though. As you start the pct start with a higher dose of SERM while using a lower dose of an AI (since there isn't much test to be attacked by aromatase enzymes in the first place). Then lower the dose of the SERM as pct progresses and increase the amount of AI being used as test rises, preventing more estrogen from being formed. As receptor sites from less and less serm being used are freed up some est will also be used swaying the balance between t:e in tests favor.
In the end you'll finish your pct with more normal to less then normal levels of estrogen instead of ceasing use of a serm that only blocked the receptor sites from free flowing estrogen that has been amassing more and more as your newly produced test was being converted by aromatase into estrogen and suddenly the floodgates are opened to all receptor sites and you get a dandy rebound in estrogen.
Now this is rebound is also possible if you aren't using a suicide inhibitor for your ai (which most otc steroidal ai's are luckily) cause it will likely have an abrupt release of aromatase that was merely temporarily bound and it will go ape **** on your test converting it to estrogen.
So essentially, use both the ai and the serm, use them in moderate doses to avoid lethargy and if lethargy strikes anyways that's why we have caffeine, or maybe you need to look into cortisol control as high levels van also cause lethargy in pct.....
Don't let fear mongering run amuck folks, you always see one person say one lil thing can cause thus and such and then every one else says what can I do now extreme to avoid something that may not even ever effect me since it may not even be the actual cause of this very persons problem but was just a mere suggestion.....sheeesh
