Slin Pin Readings and Genotropin

Hey everyone. I have "self injecting" insulin needles. They are 100 unit syringes. I was wondering how many IU's would be on this syringe? Because it is a 100 Unit syringe does that mean 4 IU's is filling it only to the 4 hash mark or are IU's different then the units on the pin. Also i have genotropin ready to go, it is very similar to this picture( http://shop.anabolics-online.com/sho...genotropin.jpg ) It is a dual chamber and i was wondering how i would go about mixing it. Should i mix it all at once? is there any other way to mix it? Thank you to anyone who has any advice! I just want to make sure i have double and triple checked EVERYTHING before i start! Thanks again!

any help is greatly appreciated! (yes this is a shameless bump)

No one has got anything to offer?

yes 4 on the hash mark, very difficult to read and guage but that is it.

thank you very much, i was just unsure because it seemed like such a small amount of liquid. Thanks for the reply though! Does anyone have any advice on their preference with the dual chamber Geno?
