how long will 0.6acetic acid stay good?

[ripped691978]

Hey guys, I made 8.5cc of acetic acid about 9months ago, I used 3 or 4cc to recon my igf-1 lr3. back then.I used a 10cc sterile sealed bottle and whatman filter and have done this a few times over the years. I dont wana waste my igf-1 by using the AA if its no good.. I am guesing its good but really need some opinions at best...I have a 30cc bottle of bac water thats half empty and it had a little over a year for an experation date..Im sure someone will say use the bac water but that would be an even worse idea lasting mayb 5days, im mixing igf-1 des this time.

I'd throw it away. I don't like it when stuff has been open for too long. IGF-1 is expensive too, while sterile water is not (or shouldn't be).
