Your body controls the amount of free testosterone through a protein called Sex Hormone Binding Globulin (SHBG). The SHBG binds to your free testosterone making it unavailable for muscle building. Activate works by inhibiting (decreasing) the SHBG in your body. This means more of your testosterone is free to help with your muscle building.
There are no studies confirming the rise in free testosterone levels, but there are studies showing that lignans from stinging nettle extract inhibit SHBG and user feedback is almost unanimously positive. I myself have used Activate several times and find that it increases focus in the gym, hardens my muscles and also increased libido. 10 out of 10 stars!
6-OXO – This is a product developed and trademarked by Ergopharm. The active ingredient is 4-etioallocholen-3,6, 17-trione. There have been several studies to date that validate 6-OXO as a testosterone booster. These studies while small have shown average free testosterone increases of 126%. Longer term studies are still underway, but initial reports are positive. 9 out of 10 stars!
