Is it okay if my order arrived warm? If the gelpack is melted?
It’s nothing to worry about. We use the gelpack as a heat sink. The real risk is exposure to open air and moisture. As long as the product is tightly sealed with a desiccant and anti-oxidant it can remain stable for several weeks with little loss to potency.
Why do you mix with Ascorbic Acid (Vitamin C)?
Ascorbic acid is used for stability and convenience purposes. Ascorbic acid prevents oxidation and dilution makes measurement easier.
