What is the longest you've kept an open bottle of bac water? I used a bottle that I took a couple mL from about 8 months ago without thinking and mixed up 20 units of HGH. I filtered it and transferred it to another sterile vial like a always do. Would you guys pin it or toss it? I have used oil based vials for a LONG time but not sure if this is the right thing to do.
