TestRX® is designed to boost your own testosterone. You’ll have a very difficult time building muscles without this ‘man’ hormone, because testosterone boosts the rate of protein synthesis, which helps pack on muscle mass.
As well, the ingredients in TestRX® have shown in clinical studies to help oxygen flow throughout the body and assist with physical endurance.
You’ll probably recover faster with TestRX® too, because testosterone is a key factor in the speed it takes for your muscles to repair the tiny micro-tears in muscular tissue that occur after you go hard on the weights and add mass as a result.
