Just a quick question about vials.
Just say a vial contains 10ml and its does is 250mg per ml then obviously i would get 2500mg (10 shots) out of 1 vial.
My question is how can one vial be used for 10 shots?
After i have jammed it wont there be a hole in the top?
This would allow air to get it, will this make the test turn bad??
