was wanting to know why hwen i take T-911, activate extreme, etc...i get upper stomach problems. Like I feel upper knot in my stomach. Heartburn, etc.....I think there is some ingredient these have all in common???If so, i saw magenesuim . Could that be causing this? Something in these products are causing the issue i believe. Please let me know what you guys think? Could it be hormonal or something as well? But right after i took t-911 a minute ago, i started feeling it. So i know its something in it as well as when i took any other natural test booster. Please charm in? thanks
