HCG Calc check?

[JamieDraper]

Hi everybody , just working out my HCG doses and just want somebody to tell me if am on the right track.

I have 5000ui hcg and I only have 2 ml of bac Water and would like to take 500ui

The calculation is 5000ui x 0.2cc(shot size) / 500ui (wanted dose) = 2ml

So by adding to 2 ml to my hcg and take only 0.2cc a shot that would give me 500ui ?

Thanks in advanced.
