Testagen by German American Technologies Review – One Healthy & Organic Test Booster

What Is Testagen?

Testagen is a fast-acting supplement designed to support the building of muscle, bone mass and endurance. It contains a unique blend of nutraceuticals – vitamins, herbs and immune-supporting compounds that encourage the body’s production of testosterone and hormone precursors while increasing endurance and overall strength.

Increasing testosterone levels has many benefits for athletes of all kinds. For athletes in weight lifting and bodybuilding, this essential hormone helps to keep energy levels up and increases muscle mass, strength and bone density. It also supports overall health, helps repair small muscle tears that occur during hard workouts, and enhances the endurance and competitiveness needed to take workouts to the next level.

Testosterone supplements are widely used among athletes of all levels, but these supplements work in different ways to boost levels of naturally occurring male hormones in the body. Raising the body’s own hormone levels helps process energy more efficiently and support the development of muscle tissue, as well as improving recovery time after exercise.

Healthy hormone levels also contribute to better circulation and oxygenation of the blood, which gives athletes greater endurance and concentration during workouts. In order to achieve these benefits, this supplement contains a unique formula that supports not only hormone production but also promotes healthy circulation, liver function and tissue growth

This product’s lengthy list of ingredients includes Vitamins E and B6, as well as zinc, selenium, chromium and magnesium. Herbs such as Mexican wild yam, fenugreek and Tribulus Terrestris work with amino acids and hormone precursors to support the body’s own natural production of testosterone while adding benefits such as immune system and circulation support. Along with iprifavone and diindolylmethane to inhibit the production of estrogen, these ingredients encourage blood flow, healthy muscle gain, increased endurance during workouts and overall gains in strength.

This unique blend of vitamins, herbs and hormone boosting compounds is absorbed rapidly and works quickly so users see fast results in muscle mass, endurance and strength without the side effects often caused by other supplements of this kind.

Endorsed by numerous international competitors in bodybuilding and other athletics, Testagen promises rapid muscle gain and endurance for hard workouts with few or none of the side effects of typical strength and endurance boosters. It can be used alone or with other performance enhancing products to produce measurable results in a short time. This product is sold in bottles of 120 caplets, about a one-month supply at the recommended dose of 4 caplets per day.

How Does Testagen Work?

Testosterone is essential for overall health as well as for building strength, muscle and endurance, but the body’s natural levels of this hormone can fluctuate due to many factors. Hormone boosters like Testagen work by stimulating the body’s own production of precursors – chemicals that create conditions that support the natural creation of this essential hormone At the same time, it suppresses the production of estrogen and other hormones that can contribute to lower levels.

This product contains androsterone, a precursor that encourages the production of testosterone in larger quantities along with other vitamins and herbs that create conditions for the natural release of the hormone into the system. Along with bodybuilding favorites ipriflavone and diindyolylmethane, these ingredients also suppress the production of inhibiting hormones such as estrogen.

Building muscle also requires a strong flow of blood and oxygen throughout the body to rebuild muscle tissues, repair injuries and boost energy. Testagen contains Vitamin B6 and herbal ingredients including Asian ginseng to keep blood vessels open and oxygen flowing to the brain and body. Other herbal ingredients such as black pepper encourage the rapid absorption of the formula for quick action and fast results in workouts.

Taken daily on both training and non-training days, Testagen promises to help users work out longer and harder for better muscle development and strength. The manufacturer GAT recommends that users take a break after finishing a cycle of the product, then starting it again.


Ingredients of Testagen

This product’s formula of 29 nutraceuticals supports building muscle in three key ways. This supplement includes ingredients that encourage hormone precursors, lower inhibiting hormones such as estrogen, and boost overall endurance and energy by supporting circulation, oxygenation and healthy nerve and tissue development. Testagen contains a blend of essential vitamins and its “Mass, Strength and Size Formula,” a combination of testosterone support, herbs and other compounds designed to support muscle development, blood oxygenation and bone density. The main formulation contains the steroid 3b-Hydroxy-5-Androsten-17-One, or androsterone. This hormone is a precursor to the production of the hormone itself.

The body also produces estrogen and other hormones such as lutein, which inhibit excess testosterone production, so reducing the levels of these hormones can help to increase it. Testagen contains Diindolylmethane, an estrogen-suppressing compound created from indoles, compounds from the cruciferous plant family that also boost the immune system and help fight inflammation. Testagen also contains Vitamin E, which supports healthy hormone levels and cell development. Along with supporting the immune system and reducing inflammation, Vitamin E helps to rebuild muscle mass and reduce oxidative stress that leads to fatigue and slow recovery after workouts.

The product’s vitamin formulation includes Vitamin B6, a key nutrient that supports healthy nerve development and circulation. This improves oxygenation and helps users recover after workouts. B6 also stimulates androgen receptors, which help the body use its hormone precursors more efficiently to produce higher levels naturally. This supplement blend also contains essential trace minerals including zinc, which stimulates the release of luteinizing hormone. LH plays a key role in the production of both testosterone and human growth hormone, another major contributor to building muscle mass and bone density. Rounding out the list of vitamin and mineral ingredients are selenium, magnesium and chromium, which not only provide immune support but also contribute to bone and tissue growth for building muscle density and lean mass.

To encourage muscle development, this supplement also contains beta-alanine. This amino acid supports the production of carnosine, a compound that appears to increase endurance and the development of new muscle tissues during high intensity workouts. Carnosine supports building muscle mass and repairing muscle tears. Also on the ingredient list is ipriflavone, a non-hormonal compound popular among bodybuilders for gaining muscle and strength. Ipriflavone lowers levels of cortisol, a stress hormone that contributes to inflammation and increases endurance, bone density and muscle mass while boosting the body’s ability to use oxygen. Ipriflavone also helps to increase the efficiency of the body’s hormone precursors.

Along with vitamins and minerals, Testagen’s formula contains additional nutraceuticals specifically aimed at boosting hormone levels and improving overall workout performance. These herbs and other natural compounds not only increase endurance and strength, but also support the body’s overall healthy functioning. Leading the list of these herbal ingredients is Asian Ginseng, an ancient herb well known for its ability to promote healthy blood circulation, support nerve function and increase alertness and focus. Asian Ginseng helps to increase concentration, focus and energy, and enhances endurance and strength for bodybuilders and athletes.

A key ingredient in the “Mass, Strength and Size” formula is Tribulus Terrestris, or Puncture Vine, a compound found in many hormone boosting supplements. Extract of Tribulus Terrestris directly supports hormone production by encouraging the release of androgen precursors that signal the body to make more testosterone. The “Mass, Strength and Size” formulation also contains Mexican Wild Yam, an herb widely used for treating hormone related disorders as well as for easing muscle cramps and reducing inflammation. Among athletes and bodybuilders, Mexican Wild Yam extract is used to lower cholesterol levels and blood pressure, clear the liver of toxins and reduce fatigue.

Also on the list of hormone boosting herbal ingredients is Muncuna Pruriens seed extract, which has been linked to the suppression of estrogen and prolactin, two hormones that keep testosterone levels in balance. Lowering levels of these inhibiting hormones allows the body to produce more natural testosterone by increasing the efficiency of its precursors. This supplement’s formulation also includes and a blend of flaxseed, ginger, fenugreek and black pepper. These ingredients support quick absorption of the supplement, so that its muscle building and endurance boosting properties are available without a long lag time.
