On the 26th of Sept. I ordered 1 liter of 100mg nic. When I received it I put the nic in a cabinet until I could work on bottling it up for the freezer. Well, a few days later I fell and broke my hip, and after surgery, and rehab, I'm finally up to taking care of it. So I pull it out of the cabinet, and transfer some to a better bottle for pouring into the storage bottles, and it has turned a dark color. So what are my options with this? Can it still be frozen for use later down the road, like maybe a couple years? Thanks.
