Sinister Testosterone booster with unique and well dosed compounds designed for hardcore results, Grimlabs Sinister is an effective testosterone booster.

Once you hit 30 years of age, your natural testosterone levels naturally drop. By supplementing with compounds that are known to boost testosterone production, you can stop this assault on your testosterone levels. As a result of the Sinister, elevated estrogen levels will be destroyed and cortisol levels will be optimized, resulting in dramatic increases in testosterone.

The compounds which make Sinister so unique and potent are Euricoma L ongifoia and Dehydroepiandrosterone. Both have proven promising results in naturally elevating testosterone levels and assisting with sexual performance. In addition to lowering cortisol levels, KSM66® also reduces estrogen levels, making this an ideal addition to maintain testosterone levels while minimizing estrogen levels. 

A unique addition is resveratrol, which is an anti-inflammatory and antioxidant that helps fight diseases such as diabetes and cancer. Horny Goat Weed, Mucuna Puriens, and Longjack Extract are other additions that may help elevate testosterone levels. Bioperine® is added to help absorption and utilization of the product. Simply put, this isn’t your average “test booster,” but a product for the hardcore user who wants extreme results.
