Got a question for you bros,

Was checking on some humalog insulin and didnt know which one to go with when I get ready to get it, I've still got alot of research I'm going to do before I do it.

the place i can get it at has:

Humalog Insulin
(1.5ml) cartridge

Humalog Insulin
100/ml vial

Humalog Insulin
cartridge (+free pin)

these are all by namebrand Lispro I think it is

out of these which one would be the best to get?

thanks for any info.
