that's interesting. I'm not sure if wheatgrass juice will contribute to gyne. It's funny that you post this because I actually came across some juice I was thinking of ordering the other day, and some person commented that "he felt it lowered his testosterone". Similar ingredients? Here's the amazon link to the juice. Check out the second comment down. Actually, I just tried posting the link, and it's prohibited. But if you're interested, just go to amazon.com and paste in the search "Berry Green Whole Foods by New Chapter". You will see the second comment down.
Anyhow, don't know if that directly answers your question. But it's something I'm curious about as well. I try to keep fit and drink these drinks, so I'll be following this post.
