Quick Overview

  • Naturally raises testosterone levels

  • Increases strength and lean body mass

  • Enhances muscle and toning

  • Activates metabolism

  • Boosts energy and recovery


Formulated for enhanced workouts for men, RX-4 is designed to boost the body's own natural testosterone levels. As the male body ages, the natural levels of testosterone decrease and this can result in a loss of lean muscle mass, lower metabolism, as well as lower libido. Rx-4's combination of clinically proven ingredients is designed to raise the body's own testosterone levels, increase strength and lean body mass, and boost energy and recovery. Plus, Rx-4 can enhance muscle, activate the metabolism, and provide a more efficient mode of nutrient transportation into the blood.

Rx-4 is recommended for males over 21 years of age only.
