One of the biggest available, here the needles are pink, available from chemists, which fits all normal syringes, not the screw on type though. Also, really essential, lots of patience

Otherwise, depending on the situation, I suck it into the syringe without the needle on it, then put it on, if necessary, afterwards.
Also, when I
buy VG at the chemists I thin it down with distilled water, by 10% or more, as is done by the
vape Shops that sell it.
