Got tired of using 25 gauge to draw, which takes like 3 min, so just got some 18 gauge needles. However, they call em cannons for a reason, never thought about this, but will those needles leave a whole in my vial big enough for gear to leak through?
beware of the 18ga! Since its so big it has been known to damage the rubber vial top to the point that small chunks of rubber drop into the juice. I had this happen to me first hand as well as hearing about others on this board have the same problem.
you dont want to be injecting chunks of rubber into your body.
I stick with 20/21ga to withdrawl.
kind of what i was afraid of. If this really does happen though i wonder why they sell them as it seems to be a definite health concern.
