All of our nootropic supplement ingredients are sourced for the highest quality and efficacy. We source our raw ingredients through a consistent network of suppliers to ensure that quality and potency through each production run stays consistent. Each material that enters the facility must go through a series of tests to ensure purity and potency, heavy metals and microbials all match the Certificate of Analysis provided by our suppliers. Even though all materials are tested prior to production, upon completion of production, the supplement goes through additional testing to ensure all proper label claims are met as well as a final quality control evaluation.
