I have 100 insulin syringes. They are 5/16" and 30 gauge. Is this to small to use for humatrope gh? do i need a bigger gauge or longer pin. Or am i ok with what i have. your info is greatly appreciated.

thanks bros. I know that it is subcantenous, but i wanted to make sure the growth powder doesnt hang up in the pin like winstrol does.
