hello, i cracked open a 10ml, water based test susp back in July, and have about 6ml left. I understand bacteria contamination can be a concern. It's been about 100 days....am I safe to still pin from this? Thanks
Water based is always a bit more risky, but as long as you did sanitary drawing techniques it should be just fine. Just make sure it look correct, no inclusions or unusual cloudiness or coloring.
I wouldnt let it get real old.
if its a true water based suspension I would worry if it went to long past exp.
Not worth and infection or bad reaction.
