Jimi, if you're gonna come in here and start correcting people, at least have a clue what you're talking about before you do. It does bind to the test. It will enable you to have more of the "good test" building muscle and none of it will convert to estrogen.
Here is a paragraph I copied about Proviron from steroid.com, one of the best sites for steroid research..obviously. I also included a link, for you Jimi, to educate yourself better about Proviron. Here is the paragraph as well, as I sense you may be too lazy to actually read the whole proviron profile. I hope this helps you better understand so that next time you are trying to "help" someone, you are armed with the proper facts.
Lets delve into some of the positive points of this drug before we go any farther. Androgen Receptors are found in fat cells as well as muscle cells(5), and whilethey act on the AR in muscle cells to promote growth, they also act directly on the AR in fat cells to affect fat burning.(9)(3) The stronger the androgen binds to the A.R, the higher the lipolytic (fat burning) effect on adipose (fat)tissue(6)(2). As if thats not enough good news, some steroids (notably, testosterone) even increase the numbers of A.R. in muscle and fat (9)(7). Thus, if you are taking a simple stack of proviron and testosterone, youll have more of the test you shoot as free testosterone floating around building muscle (compliments of the Proviron), more androgen receptors to be bound to (compliments of your testosterone) by your Proviron, thus causing more fat loss. Testosterone and Proviron are a very nice synergistic stack, pretty nearly an "ideal" stack of an oral and injectable, because both drugs will actually act to enhance the effect of the other.
