# 100unit Insulin Syringe math

I am confused and want to check if my.math is correct.

I have Genotropin 5.3mg. I also have U-100 insulin syringes.

How do the lines on this syringe equate to 1iu of the Geno?

If you reconstitute with 1ml water, then 6.25 units (lines) = 1iu.

(cause iirc, it's 16iu per)

Correct, the Geno 5.3mg = 16iu.

So, basically, the number 2 on the Syringe equals two iu's of the Geno?

Drawing to 0.2 on the syringe would be about 3.2IU.

Reconstitute with 1ml and you now have 16IU in that 1ml solution. That means the full insulin syringe would be 16IU. Drawing to 0.5 on the syringe would be 8IU, drawing to 0.25 on the syringe would be 4.

When you say "0.5," do you mean between the first line and the number "1"?

You're talking in decimals here.

If I pulled in fluid to the 2 line, how many IU's of Geno is that?

If you pull to the '20' line, you'd have 3.2iu.

He meant 0.5 as in half a ml (1/2 of the syringe), or the '50' line.

Understood.

Thanks, gents.

Use simple proportion calculation to keep you in line. This assumes you're rehydrating with exactly 1mL of water, which is 100 units.

If 100 Units = 16iu, then:

Multiple the number of IU's you want to inject by 100, and then divide by 16.

For example, if you want to inject 2iu:
2 * 100 = 200; 200 / 16 = 12.5
You would draw to the 12.5 unit line on the syringe to inject 2iu.

For example, if you want to inject 5.5 IU:
5.5 * 100 = 550; 550 / 16 = 34.375
You would draw to approximately the 34.4 unit line on the syringe to inject 5.5iu

For the sake of comparison, let's say your vial only had 12iu of HGH and you mix that with 1mL (100 units) of water. If you wanted to inject 3.5iu of GH, here's the calculation:

3.5iu * 100units = 350; 350 / 12 = 29.2
You would draw to approximately the 29 unit line on the syringe to inject 3.5iu

....or to make it really easy in your case, just mix your GH with 1.6mL of bacteriostatic water.

If you do that, every 10 line on your syringe is 1iu.
