Paraphernalia - insulin syringes and the pharmacy, what insulin?

[JaWill88]

im not sure if this is the right place for this thread and my appologies if that is the case. swim always uses insulin syringes to do his cocaine and heroin. swim gets them from the pharmacy. swim gets them 90% of the time. but that other 10% is what this thread is regarding. for that 10% the question after asking for 1cc 5/16" insulin syringes is "what kind of insulin do you use?" and of course swims answer is always... "none". and then swim is embarrased and leaves. swim would like to know what the correct answer would be. any help would be GREATLY APPRECIATED.
