So im new here and I am starting my first ever cycle of AAS, I've done PH before, and decided to do the real thing. I have been reading countless articles on various websites as far as safe injections go prior to ordering. I will be running 300mg/week test e using a 21g pin. Now here is the part i wasn't expecting. I was expecting a little rubber stopper which would be easy to open and inject. I have absolutely no clue how to get this open.
