Testogen-XR is Ronnie Coleman’s Signature Series testosterone booster, backed by real clinical trials. Formulated to increase testosterone levels and boost nitric oxide in the bloodstream, Testogen-XR also supports metabolic speed, muscle growth and sex drive. This product is one of a kind and recommended for any male athlete looking to supplement their testosterone levels.
The inclusion of D-Aspartic Acid as the first major testosterone boosting ingredient should be applauded, as it is by far one of the more effective ingredients capable of increasing testosterone levels. As with many good testosterone boosting supplements, Ronnie Coleman has also included aromatase inhibitors for good measure, including Calcium D-Glucarate and Red Wine (containing reservatrol) to help reduce levels of oestrogen. Testogen-XR certainly ticks all the boxes in terms of a quality, testosterone boosting growth matrix.
