Increase Testosterone & Training Performance
Six Star® Testosterone Booster is manufactured according to cGMP standards, as is required for all dietary supplements.
¹Six Star® Testosterone Booster is formulated with a precise dose of the mineral boron, which is shown in human clinical research to increase active (free) testosterone in just 7 days.
²Six Star® Testosterone Booster is also scientifically engineered with a unique, plant-based blend shown in a 7-week human clinical study to help maintain peak testosterone-to-cortisol ratio after an intense training regimen. Cortisol is a hormone released due to stress that can break down muscle tissue. Test subjects also enhanced performance as determined by a marker of training capacity.
