How does TestRX Work?
TestRX helps guys build bigger muscles, boost aerobic performance, lose weight, and even shifts your sex drive into high gear.
The short version of how TestRX works is that it encourages your body to make more testosterone. Testosterone boosts the rate of protein synthesis, which helps build muscle mass. In addition to that, it limits a catabolic hormone called cortisol, which breaks down muscle tissue.
Amino acids make proteins. Protein fuels muscle growth. But your body’s ability to use protein for bigger guns depends on its bioavailability.
Testosterone helps with protein synthesis by binding to androgen receptors in your muscle cells. Your body can then use that protein to repair the tiny micro-tears that occur in your tissues after you hit the weights, and that builds muscle as a result.
