eo has no smell, that dumb ass people on the internet confusing guiacol with eo. also just a tip BD barrels blow, and nipro is even worse. if you want hands down the best combination for injections you buy exel syringes with the no loss plunger (it has a nipple that fills the luer lock hub so you get everything out). then you buy terumo needles which have been proven in studies to be the sharpest needle available. the exel plungers are the most solvent resistant i have found. even drawing 100% eo the plungers will not degrade if you inject right away.

nipro plungers will degrade with less than 10% eo in just a minute or less sometimes. i guarantee the exel terumo combo to be the best out there. terumo needles are much harder to come by these days only 1 or 2 suppliers but well worth it. i usually order 300 plus at a time.
