what size slin pins should i be using for hcg? 28g-30g im sure but some say 1/2cc or 3/10cc. im not quite sure on the conversion either. i've never seen an insulin pin, but how would i get 500iu out of 5000iu in 1ml of fluid? thanks.

wait i think i found it. 1ml = 100 units..? if this is right then i would just do 10iu shots, right? :stupid

so now do i just go with the smallest pin?

Im use 29g 1/2 insulin pins for hcg. and yes 100units =1ml

Last time i measured mine it was 13 inches
