Testofen is an extract derived from the plant Fenugreek. It is rumored by some to be a testosterone booster, however that data has been heavily debated. It appears frequently in over the counter male enhancement products where it is marketed as an erectile aid and libido booster.
Testofen is a blend of over 100 different phytochemicals including steroidal saponins, which are thought to potentially have pro-testosterone effects. It is also possibly effective for helping to control diabetes and the symptoms of dysmenorrhea, and it may be helpful for regulating blood sugar and insulin levels.
