Testofen is the male enhancement industry’s new golden goose.

Recommended by consumers and experts alike, Testofen is touted as the natural solution for boosting testosterone production, enhancing muscle growth, and stimulating sex drive.

Furthermore, Testofen is extremely versatile, offering multiple applications and a wide variety of active compounds. It’s also a key ingredient in the most popular supplements such as Syntheroid and Alpha T1.

But what makes Testofen stand out in a crowd?

What is Testofen?

Created and Patented by Gencor Pacific INC, Testofen is a unique compound derived from fenugreek seeds.

Traditionally speaking, fenugreek herbs were used to add flavor to food, improve women’s lactation, and treat digestive problems. However, with the discovery of a new component in the seeds, Fenugreek has proven to be an effective testosterone booster as well.

The component is Fenuside, a combination of saponins that naturally stimulate androgen production. As a result, muscle mass and sexual functions are increased.

Saponins in Fenugreek
• Protodisoscin
• Pseudo Protodioscin
• Gracillin
• Protogracillin
• Diosgenin
• Dioscin

There are additional saponins in fenugreek that have not been identified.

Is Testofen Clinically Proven?

Both fenugreek and its patented compound Testofen have been extensively studied, in human and animal trials.

In one study conducted by Phytotherapy Research [1], researchers analyzed Testofen’s effect on male libido.

The study involved 60 healthy males between the ages of 25 and 52, without erectile dysfunction. The group was randomly divided into two groups: one group received an active 600 mg Testofen dose while the other received a placebo.

It was concluded, “Testofen had a positive effect on QOL [quality of life] in self-reported satisfaction with muscle strength, energy and well-being but did not have an effect on sleep.” However, testosterone levels in this particular study remained the same.

In a different study[2] conducted by the Journal of the International Society of Sports Nutrition, researchers analyzed fenugreek’s effects on strength, body composition, and power output.

Nearly 50 resistance-trained men (matched in bodyweight) were randomly assigned either a placebo or a Fenugreek supplement. After 8 weeks of resistance training, split into two upper and lower extremity workouts per week, subjects underwent hydrodensiometry body composition testing.

The results?

“500 mg of this proprietary fenugreek extraction had a significant impact on upper and lower body strength and body composition in comparison to placebo in a double blind controlled trial. These changes were obtained with no clinical side effects.”

While these studies are promising, a few researchers found conflicting results.

According to researchers at the International Journal of Exercise Science, Fenugreek had no effect on resistance trained males. [3]

“Supplementation of fenugreek extract resulted in a decrease in serum DHT levels [a testosterone boosting hormone] in comparison to placebo. . .supplementation of fenugreek extract does not appear to affect hormonal status in resistance trained males and dhows no anabolic potential as has been purported.”

Should You Be Concerned About Side Effects?

Most studies, reviews, and anecdotal evidence suggest Fenugreek (and Testofen) does not cause long-lasting or severe negative side effects.

When taken in high doses it may cause mild gastrointestinal distress, but it should be safe for regular use.

Who Makes TestoFen?

Testofen is manufactured by Gencor Pacific INC. USA. The company has conducted several in-house studies on animals [4], as well as a two human trials – one on exercise performance[5], and another on adult male libido[6].

Is Testofen a Good Ingredient?

Testofen offers multiple benefits with very few side effects, so it’s definitely worth further investigation.

However, like so many other ingredients before it, Testofen is severely overhyped. Though it packs a lot of potential as a testosterone booster and aphrodisiac, don’t believe every advertisement you read.
