Over the last month I have noticed increased strength and endurance that I attribute to an increase in testosterone brought on by daily supplementation with Test Stack Rx. I have more energy and wake up each morning well rested and ready to go. I would definitely recommend Test Stack Rx to anyone who is starting to feel a little sluggish in the gym as they get older. I am starting to push weights like I did 10-15 years ago and the only change I have made is adding Test Stack Rx to my daily supplement regiment.
