How we do it

Our comprehensive infrastructure enables us to tightly control every step of the manufacturing process, allowing us to ensure that quality is never sacrificed. Our onsite laboratory continuously monitors the output of the production facilities to ensure the highest quality of finished goods. We conduct extensive laboratory testing on the industry standard for state-of-the-art laboratory equipment. All products are meticulously examined for weight, ingredient homogeneity, color standardization, and content levels. Tablets are tested for hardness, thickness, dissolution, and integrity.
