Take 1-2 tablets in the morning and 1 tablet after lunch. Do not exceed 4 tablets daily. Fastin is heat and moisture sensitive, and the bottle should remain sealed after using. Keep desiccant in the bottle to avoid moisture. Store at room temperature 59-86 degrees F, protected from moisture, heat, and light. Failure to do so may cause pills to slightly turn brown. This will not affect the efficacy, potency or safety of the product, but will cause Fastin to become brittle.
