I've been training for awhile, since 92' so I've encountered pain before, but the other day I was training chest my head felt like it was going to explode, I just started taking NOX2 pinnacle, and had 3-4 servings Nitrotech within 10 hrs also a regular meal. I have used all of these products before without this result, now 3 days later I still have some residual effects, I am afraid to train, Plus I'm in Iraq without proper medical equipment to check my head... fuckin worried man,
