If you want to get extra fancy, German made, needleless spike with a 5um particle filter for the fluid, automatic 1um air filtered venting (dude with the extra
dusty house needs this!) to equalize vial pressure for easy drawing, auto closing bacteria tight valve when syringe is disconnected, and a built in cap the best deal I've found is Altruan (search for 4550579). Buy 50, choose "auto delivery 6 months" to get $10 off and pay by paypal to get them for $2.49 each. Then cancel subscription.
Only downside is $35 DHL express shipping to US, but these are $12 each in the US so it's still a good deal.
Peptide vial size micro spike version is item 4550528 . Remember you need to use luer lock syringes though, regular insulin syringes with permanently attached needles won't work.
