Hey man i did my 5th week pin a few mins ago, and i was kind of shaky when i iniected i could feel something wasnt right, i pulled out and blood startedcto come out a good bit kind of squirting, i did the pin in my quad. The bleeding stoped short after and i pinned the rest of the cc in my glutes. Now i can see and feel a small bump in my quad, it kind of hurts but i dont think its anything major. This ever happent to anyone, i think i tore a bit of the muscle tissue, or maybe hit a vein, either way i seem to be ok just a small bump
