Somatropin dosages

I will be using HGH 3iu ED 5/2. Question is I have Somatropin 9mg (Approx. 27iu) and will be reconstituting it with 2.7ml of bacteriostatic water. According to this dilution scale 1unit= 0.1ml (the "10" on the insulin dart). So I would be injecting (SQ) 30 mark on slin dart correct? Also, any opinions on drawing up extra Bwater then GH to make sure no residual is left in syringe? :scratch:

Correct on the amount to measure for 3iu..

And I would not go through "rinsing" the needle and re-injecting. The plunger is squegeeing everything out and you could be risking infection.
