i have been using the ttokkyo stanol v now for 2 weeks and i know there is a lot left in the bottle. i cant seem to extract anymore of it with a brand new 18 gauge needle. what should i do
Shoot a bunch of air into the vial. Like 6-9cc's worth. It will draw then. You should always be shooting like 3cc's of air into the vial before each shot, just so you know next time. It helps push the liquid out.
