According to Dr. Ridwan Shabsigh of Columbia University, testosterone plays a critical role in men's physical and psychological health. Its metabolic effects include supporting muscle mass, stoking energy levels, and suppressing body fat. Cognitively, it positively impacts concentration and mood. BSN developed Evotest powder to help men attain optimal testosterone levels for improved health both in and out of the gym. The effervescent drink mix blends in just six ounces of water, dissolving a concentrated matrix of more than 10 ingredients, such as magnesium oxide and d-aspartic acid. Along with fenugreek, ginkgo, and other botanical extracts, these components may boost testosterone levels when combined with a healthy diet and regular exercise, such as bar fighting.
