Testofen is brand-name fenugreek extract. Fenugreek seeds are used to make medicine because they contain numerous natural chemicals. This plant is also a common ingredient in traditional Indian remedies.
Testofen’s saponins are intended to increase free testosterone and provide other men’s health benefits.
As a brand-name ingredient, Testofen is primarily intended to boost testosterone in men aged 30 and over. Testofen is said to increase free testosterone, the biologically active form.
An unpublished study examined Testofen’s effects on free testosterone. Men in this study experienced a “significant increase in free testosterone.”
Increasing free testosterone leads to several additional benefits. Consequently, Testofen is tested for its effects on libido, sexual performance, energy, muscle mass, and fat loss.
One Testofen study primarily evaluated its libido-enhancing effects. Men in this study were aged between 25 and 52 years old. After taking Testofen for 6 weeks, these men reported improvements in libido, arousal, and orgasm. They also noted better energy and muscular strength.
Another study of Testofen’s active chemical components resulted in enlarged pelvic muscles. This effect likely enhances sexual performance.
Evidence of Testofen’s weight loss and muscle-building effects comes primarily from the unpublished free testosterone study. Participants in this study had a decrease in body fat but maintained muscle mass.
Testofen’s source plant, fenugreek, is commonly eaten as a food. Dosages similar to typical food intake are considered safe.
No long-term side effects of Testofen or fenugreek are known.
Testofen may cause side effects similar to those of fenugreek. These side effects include:
- Upset Stomach
- Urine Or Sweat Smelling Like Maple Syrup
Some people are allergic to fenugreek. Allergic reactions range from minor congestion, coughing, and wheezing to severe reactions such as fainting. It is unclear if Testofen causes similar reactions. Testofen clinical trials did not report side effects or allergic reactions.
Testofen is intended for men. Still, pregnant women should not take Testofen because fenugreek possibly induces early labor.
Testofen clinical trials used varying dosages. In the most promising study, the effective dosage was 600 mg, taken as 300 mg twice daily.
