If you want to handle GHK-Cu in a non dangerous way, keep the major vial in the refrigerator and only take out of it as much as you need for a few days into different syringes so that the substance does not lose its properties. Try to keep the product cold (2–8 °C) and also, if it is possible, save it from the light and the air. In case you have to keep it for more than a week, divide it into several small portions, put them in the freezer, and defrost each only once before using.
