.5ml syringe

James · Mar 25, 2017

I want to make the move to a .5ml insulin syringe. I'll inject 50mg twice weekly of 200mg/ml cypionate. What notch/line would that be on the syringe? I've thought about it for a while and the numbers just aren't adding up correctly. Thanks guys!

200/4 = 50mg

1/4 = .25mL

Another way to think of it is that you can double the mL to get the mg. So 1mL = 200mg.

200mg/ml = 20mg/0.1 mil (a tenth of a ml)

10 X 20 = 200

2.5 X 20mg = 50mg

2.5 X 0.1 ml = 0.25 ml

50 mg = 0.25ml

0.25mil is 1/2 of 0.5 mil.

So for a 1/2 ml (0.5ml) syringe you would need to fill it 1/2 way (50%)

If my math is off I am sure someone will correct me.

johndoesmith - those numbers make sense if using a 1 ml syringe. I'm currently injecting 60mg twice weekly and fill to .30ml. You think it would it be the same with a .5ml syringe.

Orrin - There's no way I'm doing that kind of math brother.

Of course, .25ml is .25ml regardless if it's in a .5ml syringe or a 1ml syringe. Good picture Vince.

The numbers still make perfect sense, mL is mL no matter what. A .5mL syringe can only hold up to .5mL, but that has no bearing on the amount of volume the units measure.
