Mixing and storage

There is nothing to mix: it arrives as a yellow liquid ampoule, about 3 mg of active material in 10 mL, with the colour coming from riboflavin. Keep it cool, dark and sealed, because riboflavin is broken down by light and the botanical extracts do not improve with warmth. The ampoule carries no preservative, so it is opened and used fully in one sitting and the remainder let go, which the maker states directly. Buy through a chain of supply you can name, since the published laboratory analysis of samples sold under this name found ingredients that did not match the label and varied from pack to pack.
