my friend and I are used to injections, and sometimes we will do it for eachother so it is easier. we used to draw back and check for blood all the time, and never had a problem with blood but little annoying bubbles would come in to syringe... anyway, this time i forgot to, and when half of the juice (1ccDeca and 1cc sustanon) was already squeezed into him, he said "DUDE MY WHOLE ARM IS TINGLING, SOMETHING ISNT RIGHT!" so i curiously stopped injecting and pulled back on the syringe and a SHITLOAD of blood entered the syringe. i was fucking shaking and i pulled out and i didnt know what to do, neither did he. we sat and waited and he said besides a little pain throughout his arm and shoulder he was alright. we went to the store and while walking around he said to me "hey, my heart feels funny" and he said it was hurting and felt like it was stumbling... i wanted to take him to the hospital and he said he wouldnt go, soon after he was fine, so he said... has anyone ever had this happen, or known someone that has had it happen? is my friend going to be in any serious danger? please respond, i would hate to know that i killed my friend.
