So I am on my first cycle of test cypionate at 2x250 a week I'm on about week 8 now. For over a month now I'm getting terrible "backpumps" in my lower back when doing things that put pressure on my back like digging etc. Does anyone know the cause of this? I dug out a wood post yesterday and within 5 mins my back was on fire. I have never experienced this so I'm curious if the test has anything to do with it?
