Calcidum D Glucarate

I’m reposting this here because I haven’t gotten any responses in the supplement forum and people here tend be much more knowledgable and on the up-and-up:

Calcium d Glucarate is known for its anti-estrogenic properties. I’ve used it in the past and think it is a good supplement. [and a cheap one]. But I’ve recently heard some talk that it can also reduce ‘excess’ testosterone. Anyone know anything about this? Think it’s something to be concerned with?
