Ok, so I plan on loading both test cyp and tren-e into a 27 gauge slin pin. What is the best way to go about this?
Do I need to inject air into vial 1, remove the pin, inject air into vial 2 and draw, and finally reinsert into vial 1 and draw.
Seems like the only way to do this while using only one pin. The needle would have to go through 3 rubber stoppers before I inject. Maybe there's a better way? What do you guys do?
