Testogen Ultimate contains ingredients that help prevent the conversion of testosterone to estrogen. One such ingredient is fenugreek extract, a natural compound that has been shown to inhibit the activity of inhibitory enzymes responsible for converting testosterone to estrogen.

By inhibiting the activity of these enzymes, fenugreek extract helps reduce the conversion of testosterone to estrogen, which in turn helps maintain healthy testosterone levels in the body.

In addition, Testogen Ultimate also contains other ingredients that have been shown to support healthy testosterone levels, such as boron, Korean red ginseng, vitamin D, vitamin K1, and others. These ingredients work together to prevent the conversion of testosterone to estrogen and support overall health.
