Functional Muscle Fitness LLC specializes in functional training and athletic performance training. We only recommend supplementation that is of the highest standards. The supplement industry is not regulated by the FDA; therefore, it is important to acknowledge this fact by looking at the company backing the product. We at Functional Muscle Fitness LLC have used these products ourselves. However, understand that supplementation works better for some then it does for others. You except responsibility for purchasing any supplements and understand that FMF has no legal responsibilities to you for any reason. Also, if you are a NCAA athlete, Olympic athlete, or a professional athlete please check with your sports organization to check if any ingredients are on the banned list for your organization.
