Unless stated otherwise we guarantee a shelf life of 2 years from the date of manufacture with proper storage and handling.
For a more detailed answer, let’s take altitude. Due to the second law of thermodynamics entropy is always increasing. As a result the active chemical molecules of a product are always degrading, albeit slowly. Eventually there will be a measurable decrease in potency. This can take several years with proper handling and storage.
Unfortunately we can’t provide a more precise answer. True shelf life is variable and in most cases little data is available for novel compounds. Shelf life decreases with exposure to heat, moisture, oxygen and sunlight, which can create free radicals and break chemical bonds. Shelf life can be extended by deep freeze (-20ºC or -80ºC). A powder ingredient in deep freeze could have a shelf life in excess of 10 years with minimal degradation. It is not recommended to store a liquid, oil or solution product at anything below room temperature because this will alter the solubility properties and may precipitate the mixture, rendering it non-uniform and difficult to measure without resuspension.
