Bodybuilding supplements can help build muscle and increase energy, but also carry health risks if overused. Creatine increases muscle size but causes water retention and potential dehydration. Glutamine aids recovery without side effects. Andro supplements increase muscle but also male hormones in women, raising heart disease risk. Caffeine boosts fat burning but too much causes jitters, irritability and other issues. Bodybuilders must carefully research supplements before use to maximize benefits and avoid health problems.
