I've got 5000ui of hcg and 1ml of sterile solution, both in amps.
I want to shoot with slin pins (28g x 1/2" x 1cc), but the pins won't reach the bottom of the amps (from the looks).
My question is, would it be wise to transfer the reconstituted solution from the amp into a spent hcg vial that has the stopper intact? Using a 22g x 1.5" 3cc pin to draw and transfer.

Intramuscular is not an option right now since shooting 500ui out of a 3cc syringe would be inaccurate.
