How does Test RX work? Test RX has been designed to boost your own testosterone. Men have a very hard time trying to build muscles without this male hormone that diminishes with age, because testosterone will boost the rate of growing protein synthesis that helps pack on severe muscle mass during work outs. Ingredients in Test RX have shown in clinical studies to really help the body with oxygen flow and assist physical endurance.
Recover faster with Test RX too because more testosterone is a key factor it takes the body to recover and the speed it takes for muscles to repair all ripped tiny micro-tears in muscular tissue that break down after going hard on the weights.
This quicker recovery will add muscle mass as a result of using Test RX!
