i was doing a delt injection, 333mg of test, 1cc, 23g pin, i was pushing in, and for some reason it wouldnt go, but i had no pain in pushing, i ketp pushing and finally, i felt this click, and the pin shot all the way in, it kinda freaked me out, i aspirated, no blood, no pain, shot, not pain, no blood, so what the f**k was i breaking through, usually scare tissue is much more painful
