The way to avoid hitting a vein is to first inject in the correct areas of the muscles, and 2nd to aspirate . Aspiration is as follows: after you stick the needle in you pull up on the plunger slightly. You should either see blood enter the syringe or bubbles. If there are bubbles you are good to go, if blood then it means you prob hit a vein.
The key is to inject slowly. If you inject slowly minimal amounts will enter your bloodstream before you begin coughing violently and feeling nauseaous, and as long as you don’t keep shooting you will probably be fine. You will feel like shit, but you probably won’t die.
But like as everyone else said you are too young bro and you haven’t done nearly enough research. If you were a 40 year old asking these questions I would tell you to research more so don’t just think it’s because of your age. But again you are too young to be juicing.
