Study Result: Increase Free Testosterone in Just 7 Days
1: Professional Strength Testosterone Booster is formulated with a concentrated and precise dose of boron, which is shown in human clinical research to increase free testosterone in just 7 days. Free testosterone is the most active form of testosterone and is critical to initiating the process of muscle building.*

Maintain Peak Test to Cortisol Ratio & Enhance Performance*
2: Professional Strength Testosterone Booster is also scientifically engineered with Rhodiola crenulata and Ginkgo biloba. In a 7-week human clinical study, subjects taking this combination maintained peak testosterone to cortisol ratio after an intense training regimen. While testosterone is important to keeping your body in a muscle building state, cortisol is a hormone released due to stress from training and can break down muscle tissue. Test subjects also enhanced performance as determined by a marker of training capacity.*
