On the second time the is positive pressure in the vial. As I draw the HGH is slowly draw the pin out at the same time until HGH stops drawing. That means my pin is in the rubber and will not draw any more fluid. Then I slowly push the pin back into the vial until the fluid flows again. The positive pressure pushes the rest of the HGH out and i have nothing left in the vial. Works for me.
