Around four weeks ago i started injecting 250mg of test e a week(trt) split between two shots, rotating between quads and right glute. The first 3 or so shots were fine, but the shots since then in my quads have been giving me trouble. When i insert the needle(1.25, 23g) im getting pretty bad muscle twitches like im about to hit a nerve, lady at the needle exchange said that hitting a nerve directly can be some of the most painful shit one can experience, any truth to this? Normally im 100% comfortable giving myself injections, but this scares me.... Next, my last 4 quad shots have leaked blood and oil every shot , i insert the needle as deep as possible, inject very slowly, and even left the needle in for a full minute last shot, it didn't help and the shot before that in the opposite guad felt like it leaked right out into the subq tissues because the pip was right under the skin and not deep in the muscle. If anyone has any advice its highly appreciated.
