I'm assuming your meaning 4iu/day... Is this a Kexing kit?(nevermind, I just read it was a soma kit)
you should get U100 slin pins, they are much easier to read. Just fill the pin to the 60 line, mix with the HGH and then each 20 is 4iu's.
What are your goals with running the HGH (gain mass, lose fat, etc...), do you have enough on hand to get you through a couple of months?
