well the ama can say what it wants....but there is nothing that beats the feeling of a brand new needle inserted into your muscle

....ive been known to resuse needles up to 3 or 4 times before, back in the day, and all i noticed was it being harder and harder to break the skin......get a new needle it will glide right in.....i mean there is a right way to do things ...clean your hands, wipe vial with alcohol, wipe area etc...just do that **** and get a new needle to inject....they arent that expensive that u need to be stingy haha whats the difference
p.s. i forget where cuz i look over 5 or 6 different boards but i remember somone posting 4 pictures....one for each of the first 4 times....it was magnified over and over and was intresting to see...i wish i could find the link
