how much does proviron lower estrogen?

any ideas compared to arimidex ?

I have been researching proviron AI efficiency and found nothing.
Bump for this, I am interested also.

Have a read on a clip from AR's profile on Proviron...there are clearly mechanisms at work that prevent estrogen aromatization...and this effect seems to have a synergistic effect if Proviron is stacked in a cycle, hence exhibiting some AI properties on the other compounds in the stack....

Proviron.

So lets go back to the comparison with being some sort of "Oral Masteron"& basically since Proviron is 5-alpha reduced and not capable of forming estrogen, and also has a very high affinity for binding to the aromatase enzyme (the enzyme responsible for converting all that good testosterone in your body into all that nasty estrogen). That means if you choose to take proviron with testosterone (and I know you wouldn´t even be doing a cycle without including some form of testosterone) and/or any aromatizable steroid, it should actually serve to prevent estrogen build up by the aforementioned binding to the aromatase enzyme, which prevents aromatase from doing it´s dirty work and making a bunch of estrogen out of the other steroids you are taking. It should also be noted that Proviron also binds very well to SHBG (Sex Hormone Binding Globulin& a hormone responsible for reducing the amount of circulating free testosterone in your body)(1). As a matter of fact, in the last study I read, it bound to SHBG better than any other drug studied. Also, I´d like to note that Proviron bound to the Anabolic Receptor better than any oral anabolic (except for the insanely toxic MethylTrienolone), having an ability to bind to the AR better then testosterone, but not as well as Nandrolone (1). Unfortunately, as we know, DHT also has a high affinity for binding to receptors in the scalp and prostate, causing some possible nasty side effects, like male pattern baldness and prostate enlargement. It´s important to remember that DHT and DHT derived compounds are used quite successfully to treat gynocomastia, and in this area, Proviron is no different.

I had seen that before. What I would like to know is like what you see in the profiles for Aromasin , Arimidex or Letro where it shows how much these compounds can prevent estrogen convertion (in percentage). I don't even know if there is a study about it, as I have been researching for a while.

i really dont think its that much, my dht got tested BEFORE me going on masteron at 100 mg EOD, and it was 1500 on the scale of >500 and my estro could still climb.
