World's Most Clinically-Researched Fenugreek Seed Extract

Testofen® is a patented Fenugreek extract standardized for 50% Fenuside™ proven to naturally boost testosterone levels.

Testofen® is a unique extract of Trigonella foenum-graecum seed standardized to a proprietary matrix of saponin glycosides that Gencor has named Fenuside™. These constituents have been clinically-proven to boost testosterone levels, support healthy sexual desire and vitality, muscle mass and power, which help increase sports performance and reduce symptoms of andropause in men.

Supplementing with Testofen® with regular resistance exercise can help men maintain healthy levels of free testosterone that are already within the normal range, which, in turn, supports multiple bodily functions.
