Empty vials on the way, but could I just transfer my research peptides back into the bac vial?

[desinr-gal]

I am a newbie, please have patience..I received 70mg of Glo in a 2ml vial. I also have 3 new vials of 3ml bac water available. Could I just draw 50cc, (or 1ml) each from two vials of bac, recon in the glo vial, then draw back up 50cc/1ml and inject back into each bac vial? I have ordered 5ml sterile vials but it may take awhile, and someone said they may not actually be sterile.
The ones I have all came from Atomik, their own bac not Hospira.
Advice?
