All manufacturers of dietary supplements must ensure that the muscle growth products they sell are safe under the terms of the Dietary Supplement Health and Education Act, DSHEA, of 1994. Manufacturers do not have to receive approval from the Food and Drug Administration when they want to sell or market any dietary supplements, including those that aid in muscle growth.
