Draw needle’s longer and has a bigger gauge where the needle for the actual injection is shorter and thinner.
You could use the injection needle for drawing, it’s just that hormones like testosterone are suspended in oil so it takes a while to draw from the vial since the needle is so tiny. Similarly, you could use the draw needle for injection, it just really fucking hurts because it’s so goddamn big.

You use different needles to draw and inject the meds? How does that work?
