I have tried supplements from a variety of manufacturers and nothing compares to Fit+Well Dynamics. It is so hard to find supplements made from quality natural ingredients with no artificial flavorings, preservatives, colors, sweeteners or other junk. BIOFUEL MAX is my favorite (I take it even the days I'm not working out!). I have also found BCAA 411+ and G-FORCE have been highly effective in improving my strength and endurance. They taste really good and don’t use harsh stimulants that make me feel like I have had 5 cups of coffee.
