I have a quick question for anyone with experience using TRT injections and Luer-lock syringes.
If you draw up to the 0.2 mL mark on a 1 mL syringe, is the dose based only on where the plunger is, or should I also count the oil that sits in the luer-lock hub and the space above the zero line?

I noticed that when I draw a small air bubble into the hub, the oil reading is closer to 0.3 mL than to 0.2 mL. This makes me wonder if I’ve misunderstood how syringe calibration works.

I use the air-lock technique with about 0.1 mL of air, but I still notice a small amount of oil remaining in the dead space after injection. Is this normal with luer-lock syringes, or could I be doing something wrong?
I’d appreciate any advice from anyone who has dealt with this before.
