Calcium D-Glucarate and Estrogen

I've found a study on PUBMED that states that Calcium D-Glucarate is a substantce that seems to regulate estrogen levels in th body.

Also found another piece (http://www.thorne.com/altmedrev/.fulltext/7/4/336.pdf) that states that Calcium D-Glucarate excretes exccess estrogen before it can be reabsorved.

If this is true, couldn't it be a good substance to take while on a PCT ?

Has anyone tried this product ? At which doses ?

Well, I'm be waiting for your opinions on the subject...
