I was just curious about this and was hoping that you guys could clear things up for me...
Scenario: When loading two compounds into a single syringe (For example Tren A/Prop or Test C/EQ)
I understand that loading an empty syringe with air of the same amount you intend to draw and then injecting that air into the vial before you draw the compound helps form a vacuum and makes drawing easier, but what's the procedure for the second vial once the first compound is loaded?
Are you able to draw more air into the loaded syringe on top of the compound and repeat the process?
Wouldn't this build a pocket of air between the two compounds in the syringe?
Maybe you can push that air to the top and eject it before pinning?
Is injecting air into the second vial even necessary?
Thanks a lot guys.
