Since 1967, Beverly International has insisted on using only the highest quality ingredients and manufacturing methods in the development of its dietary supplement formulas. Beverly International will not bring a product to market unless it is supported by peer-reviewed scientific studies. It uses these studies to determine which types of ingredients, and of what quality, are required to produce satisfying bodybuilding results. If the same quality of ingredients used in scientific studies cannot be obtained, then Beverly International will not develop the product.
