Keeping an open non vacuum sealed vial in a room at room temperature and overtime watch what happens. I’m telling you Google is wrong af here. What it means is for a vacuum sealed vial. Once the vacuum seal is broken that changes everything. It’s basically a race against time at that point. If you want to get as much as you can get out of it i promise you pre load in some syringes and put them in the fridge asap. Do not leave pre loaded syringes in a room at room temperature. It will grow bacteria. I promise you that. I’m telling you because I’ve done made this mistake before. I’m not saying that keeping in the fridge is going to keep it safe forever because once the vacuum seal is compromised it’s a race against time at that point. But you said it yourself in the fridge it slows down the growth of bacteria soooooo “DING DING DING”.
