How much is 1ml in a syringe?

[Cuz]

All I do is to fill up my syringe to 1ml from the liquid in the bottles and inject. I don't pay attention to the bottles.

Man, no disrespect you either trolling or seriously need to stop. You have no clue what you are doing or putting into your body. How do you know what you’re running if you dont even look at the mg/ml concentration? This literally makes no sense to me
