¹Six Star ® Testosterone Booster is formulated with a precise dose of the mineral boron, which has been shown in human clinical research to increase active (free) testosterone in just 7 days.
²Six Star ® Testosterone Booster is also scientifically developed with a unique plant-based blend that has been shown in a 7-week human clinical study to help maintain maximum testosterone-cortisol ratios after an intense training test. Cortisol is a hormone released due to stress that can break down muscle tissue. The subjects also improved their performance, as determined by a marker of physical performance.”
