Is dimethylamylamine a steroid? I have been taking Jack 3d, which has this ingredient in it, and now have a fluid pocket on the back of my eye ball that is pressing on my center of focus and causing me blurry vision. I was told that this is common with stress and steroid use. I have been in the Marine Corps for 21 years, so yes, I have stress in my life. This is not new to my body, so for this to happen now and with only 1 eye does not make sense. However, maybe the use of the Jack 3D with this ingredient in it might be the source of this fluid pouch. Your thoughts?
