What is Testofen?

Fenugreek seed extract is known as Testofen. Traditionally, fenugreek has been used to increase testosterone level and sex drive in men.

The extraction of fenugreek seed was started by Gencor Pacific, which later led to a patented and engineered product.

Testofen is supposed to be a standalone supplement and work as the main component for supplements like Testofen by GNC, Nugenix, Alpha T1, and Swanson Testofen.

The History of Testofen

Fenugreek is a well-known ingredient, used in cooking food, home-brewed wine, tea and other consumable items since ancient times.

Romans used it to brew their wine, and many countries still use it in cooking.

Fenugreek was also known for its medicinal effects and was used for treating several health-related issues; major ones were an enhancement of men and lactation in women. [1] [2]

Fenugreek seed extract known as Testofen was created by Gencor Pacific.

The traditional application of fenugreek was the motivation behind this product.

he company now sells its patented Testofen supplement to other companies as an ingredient for their supplements.

Testofen by GNC and Swanson Testofen are two examples.

Testofen Claims

The product claimed to improve the following:

  • Testosterone levels in men
  • Muscle growth
  • Increased sexual drive

Testofen Ingredients

The general composition of fenugreek includes:

  • 4-hydroxyisoleucine
  • Trigonelline
  • Galactomannan
  • Trigoneoside

How Does Testofen Work?

Fenugreek mainly consists of compounds which regulate blood sugar levels.

These compounds are commonly known as saponins.

Testofen ingredients are similar to fenugreek compounds, just with a higher concentration.

The steroidal saponins in Testofen slow down the absorption and production of glucose in a mammal’s body.

Studies have shown that consumption of Testofen has affected those individuals who already had obesity, type 2 diabetes or individuals with some other health condition resulting in imbalanced or excess glucose production.

Individuals without such health issues didn’t experience any changes at all. [3]

It is also observed that Testofen works better with some other nutrients; aiding and improving the targeted function.

The compounds include fish oil, arcabose and slow blood clotting agents. [1]

Testofen Benefits and Results

Traditional use of Testofen has collected some solid results, as shown in Testofen reviews from studies and by consumers.

Testofen benefits include: [4] [5] [6] [7] [8]

  • Resistance training adaptations
  • Increased endurance
  • Decreased fat accumulation
  • Improvements in blood glucose levels
  • Improvements in cholesterol levels

Testofen and Weight Loss

Testofen fenugreek extract is believed to increase testosterone levels in men.

Testosterone is of course the hormone which leads to increases in lean muscle mass and decreases in body fat.

Fat loss effects of testosterone are well known to the world.

The high energy you feel is because you burn more energy, and a routine of regular workouts can also cause a significant gain in lean muscle mass.

Testofen benefits

Fenugreek Testofen and Glucose Control

A Testofen study showing lowering of glucose levels in type 2 diabetes patients are there.

Consumption of Testofen fenugreek extract during the meals and after the meals worked for many patients.

However, Testofen dosage was between 5 to 50 grams, anything lower than that didn’t work. [9] [1]

Type 1 diabetes patients also benefited from the consumption of Testofen fenugreek seed extract.

Sugar levels in urine were decreased, but the dosage amount was rather high.

This effect is caused by the saponins present in fenugreek.

Saponins are compounds which bind to bile salts and contain antioxidant activity. [3]

Testofen and Cholesterol

Fenugreek Testofen and Cholesterol

The fenugreek seed extract known as Testofen showed a positive effect on LDL cholesterol, lowering it significantly.

This effect was attributed to the presence of saponins and dietary fibers in Testofen.

It is believed that saponins inhibit cholesterol synthesis as well as absorption, in our bodies.

However, no effect on HDL cholesterol levels has been registered so far. [10] [3]

Testofen Fenugreek and Lactation

A very common problem in lactating women these days is a decrease in the amount of milk production.

Testofen fenugreek seed extract or fenugreek may boost lactation in women. [11]

How Testofen or fenugreek causes lactation is still not confirmed.

But, it is believed that the increase in the level of phytoestrogens and diosgenin components are the reason behind this.

There are some steroidal compounds present in the Testofen supplement which can also cause lactation, as steroidal compounds have that tendency irrespective of the user’s gender.

Studies have shown an increase up to two times, but results of continuous usage are still unknown.

The increase in lactation was registered 24 to 72 hours after taking the herb or tablets.

Testofen Interactions

Taking Testofen with drugs that slow blood clotting increases the chance of bleeding and bruises.

Many Testofen reviews have stated this fact, the performance has been reported with agents like:

  • Aspirin
  • Clopidogrel
  • Ibuprofen
  • Naproxen
  • Dalteparin
  • Enoxaparin
  • Heparin
  • Warfarin

All of these medications are used to slow blood clotting, and improved performance has been observed; make sure you get your blood checked regularly. [1]

Medical benefits of fish oil are nothing new for us; it is used for several health conditions.

The omega-3 content of fish oil helps in reducing blood pressure and improves fat burning tendency.

Heart health is also affected for good, by consumption of fish oil and other benefits are there as well.

It has also been observed that consuming a mixture of 5% concentration of half fish oil and half fenugreek extract can help manage post-prandial blood sugar spikes by decreasing them significantly, showing better results than consumption of 5% mixture of fenugreek alone.

Acarbose is a compound that works as an alpha-glucosidase inhibitor, and it is used for the treatment of diabetes by managing the release of glucose into the blood when consumed in weight ratios of 1:0.8-1.2 (Arcabose: Fenugreek Gum). [12]

Fenugreek gum is the soluble fiber part, and it is able to enhance intestinal half-life.

The result is achieved by increasing the release of acarbose from being fully absorbed in one hour and by delaying complete absorption for up to 8 hours.

Fenugreek is known to work as an anti-diabetic and due to that it works well as an additive with other medications and drugs used for managing glucose spikes. [13]

Potential Testofen Side Effects

Testofen fenugreek extract reviews have shown some side effects in users which are not that major.

The observed side effects may include:

  • Diarrhea
  • Stomach upset
  • Bloating
  • Gas

There may be people who are allergic to Testofen, considering it’s in the same family as the soybean. [1] [14]

Testofen ingredients are usually safe when consumed orally in limited amounts, as prescribed.

Testofen can have benefits like blood sugar control and testosterone boosting, depending on the period of time, the dosage, and the person.

Fenugreek and fenugreek seed extract have been shown to have a positive correlation with lactation in multiple clinical studies.

Fenugreek seems to stimulate production of the hormone prolactin, which may be undesirable for some men. [15]

There can be a chance of extreme lowering of blood sugar in patients with diabetes, a constant check of blood sugar level is needed.

Consumption in limited doses that are equal to or less than levels of food has no negative impact on a person’s health in the long term. [1]


Testofen Alternatives

Testofen benefits include testosterone boosters that also can result in overall health benefits such as weight loss.

There are natural testosterone boosters which can work as alternatives of Testofen, including:

What You Should Know about Testofen

Testofen is a fenugreek supplement standardized to 50% fenuside. There are plenty of research studies completed on fenugreek and most are in relation to the effects on breast milk volume. Fenugreek is known to increase the volume of breast milk for mothers who are having trouble making enough breast milk to feed their infants. There are a few other ingredients in the supplement, but none that will greatly impact weight loss. Testofen is a product trademarked by Gencor Pacific

List of Testofen Ingredients

Fenugreek. Proprietary Catapol Blend - Ginseng, Vitamin B6, Vitamin B12, Niacin, Bioperine.

Product Features

Fenugreek is the first and foremost ingredient in Testofen. There are no studies, that we could find, to back up the claims of increased testosterone levels associated with fenugreek. The theory behind the claim of increased testosterone is linked to the milk androgenic properties of fenugreek, similar to Biomuscle XR and Test Worx. We did find plenty of studies involving women with trouble lactating. These women took fenugreek to improve breast milk supply with good success.

Vitamin B6 and vitamin B12 are commonly used to increase energy naturally. These vitamins work to metabolize carbohydrates in the body, among other actions. That metabolization allows cells of the body to use carbohydrates for energy. Some people, especially those who have had weight loss surgery, are often deficient in vitamin B6 and B12 and supplementation can increase energy and reduce fatigue.

Niacin is another B vitamin commonly used in supplements claiming to increase fat burn. Niacin causing a flushing effect which may include increased heart rate, red skin and sweating. This reaction in the body is often the reason dieters believe a weight loss supplement is burning more fat, but the flushing and fat burning are not related.

Bioperine is another name for black pepper; the same black pepper used to season food. There is some evidence that black pepper and other peppers cause an increase in body temperature and heart rate and thus affect metabolism. The rate at which metabolism is increased is not clear.

The final ingredient is Ginseng. Ginseng is often touted as a relaxant and energy booster. Studies have been performed on the supplement for decades with some positive results, similar to True Grit Test Booster. One result that dieters would be interested in was completed in 1994 in Sweden. People who used Ginseng reported increase appetite, almost across the board.

Testofen sells from various manufacturers and the price ranges from $15 to $30 per bottle.

Advantages of Testofen

  • B vitamins may increase energy metabolism and reduce fatigue.
  • Bioperine shows promise as a natural fat burner.

Disadvantages of Testofen

  • Fenugreek may not have the testosterone boosting effects promised.
  • There are not real fat burners in the supplement.
  • No appetite suppressing ingredients are included in Testofen.
  • Ginseng may increase appetite.


Testofen is supposed to boost testosterone to help increase muscle size, but the ingredient list does not support that claim. Dieters will waste their money on this product because the ingredients are not formulated to work for weight loss or fat burn, though Bioperine is a mild fat burner.

    any side effects of testoril or cautions?

    • Maribel (Editor)

      Hello Dennis, a common theme that we have observed is that users see no results or benefits from this product. Haven’t come across side-effects either, though. If you’re looking for results, check out Pronabolin to increase your physical performance and build lean muscle.

    Does it contridicts with dibitic drugs

    • Jessica (Editor)

      Hi! Because you take these medications, please make sure to consult with your physician before starting a new weight-loss program or product.

  • Helpful ANswer

    Like the other poster said, pump pump pump, as much as you can with an eltcreic pump.I had a low supply and this did it for me. If you try now it may not be too late. I had to keep pumping until around 4months, when finally my milk supply adjusted and I got to where I needed to be to exclusively breast-feed my baby.If you are comfortable with it and can do it responsibly, you could ty co-sleeping with the baby as the night-time feeds stimulate milk production more than any other time of the day. Prolactin is higher in the early hours. You could try breast-feeding lying down, that’s what we did anyway and baby and you both go back to sleep with baby attached. Breast=feeding releases a hormone that makes you feel sleepy so that you go back to sleep when baby wakes for a feed, but it also releases a hormone that stops you entering the 4th stage of sleep, the very deepest sleep, to stop you from rolling onto your baby.Anyway, I digress, good luck with it, hope you get it back Was this answer helpful?

    • ross

      The standardized fenusides help, but TESTOPEL is an implant that seriously works for what you desire. You will need to see a urologist for this. I use the fenugreek (610mg) as a boost. It works.
