Yes. Use filter syringes with amps. If medical pros do it, you should too. Or, you can be a dumbass bro and tell stories about pinning and "hitting veins" and injecting little shards of glass into your vessels like it's an awesome story that makes you cool or hardcore. Injecting little pieces of glass into your muscle tissue may not give you a stroke or anything, but I think most people would agree that it's generally not advised. Just an example, if there is something infectionous on the outside of the vial and you inject it into deep tissue, you immune system will encapsulate it with an abcess (pus-filled pocket). Because of the depth of it and possibly how much mass you have around it, it could be golf ball sized or bigger by the time you make it to a doctor. They either give you antibiotics or cut into to it to drain it, then pack it daily until it heals. It's pretty awesome, especially the rotting flesh smell that comes out with it. *Moral of the story: Don't be a bro. Inject safely and smartly.*
