Wow, I just read almost all of that pdf you posted. It makes yohimbine/yohimbe look like a killer. Damn, I was happy that enhanced works so well for me and I found a form of yohimbine that I react well too. After reading that I'm a little bit scared!. By the way, alphamine has a different form in it. Alphamine I don't react well to at all.
After reading that pdf...You can react well to Y or you can react poorly, its very individualized. Side effects are or "can be" dose dependant. I don't know it seems wishy-washy, but the jist of what I read tells me it is a dangerous product.
