I recently asked a few questions about taking the sus250 verses the tes400 that I was taking, but did not ask about this unusual knot that I have where I gave myself a shot. I took the cc on Saturday and now I have a knot nearly the size of a tennis ball in my buttocks. Is this very normal after only 2 shots of tes400? I can bare the pain, but the unusal not is discomforting and worries me that something may have gone wrong. Please fill me in...
