So I just placed an order with bestecig.com for a stock pile of juice. I grabbed 35 mL of 555, 35 mL of flu cured, 10 mL of ry4 (everyone raves about it.. but I'm not sure if I'll like a caramel vape), and 10 mL of flu cured extra high to avoid analogs while drinking My question is... does juice go bad? Has anyone found that the PG, flavor, or nicotine degrades or anything over time?
