I was eating 4 Zone bars a day. They have soy protein in them. When I visited Dr Crisler, he told me not to eat them, because the soy could raise my E2 levels.

[role model]

Yas, thay raise E2 levels.

[pmgamer18]

Well Soy does not in a sense rase e2 it has a marker like E2 and the brain can't tell the difference between the 2 and thinks it's testosterone. So if you eat enough and fill your cells wtih it your brain will think it's testosterone and stop sending the messages to your testis to make more T. If your on TRT and do a lot of SOY your cells will fill with it and you will piss the T down the drain. I had a guy post to me he had low T and lost his sex life he went on to say what a health nut he was and that he drank SOY MILK every day. I told him this was his probelm he stopped the Soy milk and in 4 weeks was fine.

Not sure how much soy I was taking in, but about 2 months ago, I started taking my protein shakes with soy milk (about 24 oz/day) instead of regular milk. I am lactose intolerant and got tired of buying lactaid.

Anyway, about 2-3 weeks in it, I started feeling like crap. Had a rash on my face and just felt in the gutter mentally. After I stopped taking the soy milk, the rash disappeared and I felt better within a few days.

Now see when my E2 is on the higher side I break out in rashs so remember this if you have a rash think about high E2.
