My HC-110 bottle is down to its last 100 mls or so and is so dark red as to be almost like a strawberry syrup. Further, there are large amounts of solid chunks in the syrup. It looks like old used waste oil. But it develops just as good as the day I opened it. It's truly amazing how robust the product is despite the clear and massive changes it undergoes. I wish the products I designed had a shelf life like HC-110.
