Is it possible to get back pumps from EQ and Test E? I heard of them from DBOL, but not anything else. Reason I'm asking is because the last two times I've played hockey I've had severe back pain. I think maybe its kidney stones?(because when I feel my lower back I have two hards little knots on both sides around where the pain is) IDK?!? I might actually have to go to the hospital for this one. Not good at all......any help/ideas? Doc???
