ahhh...
you can buy those vitamin e tabs and squirt in them and pop 'em... but i'm thinking syringe contamination isn't a big concern if you aren't injecting... just pop it in the fridge or something... spats has something on the dosing, but i'm not sure just how much that would come into play?
but i'm a complete idiot when it comes to needles... so, maybe i'm missing something
