SCIENTIFIC STUDIES

When you’re taking a supplement like TestoGen, it’s important to know that the ingredients involved actually work. Fortunately, there are tons of scientific studies that have been done on the main ingredients in the TestoGen supplement. Here are just a few of the most prominent studies done on some of these ingredients. These studies have examined hundreds of people and revealed that these herbal substances have significant and consistent positive effects on the human body.

ENHANCING EFFECTS OF FENUGREEK EXTRACT ON A MALE LIBIDO

Trigonella foenum-graecum – much more commonly referred to as Fenugreek – is a popular herb that’s been used for culinary and medicinal purposes for millennia. It has been used successfully to boost libido in both men and women.


This study, which evaluates the effect of an extract of Fenugreek sold under the brand name Testofen, followed 60 healthy men between the ages of 25 and 52. None of these men struggled with erectile dysfunction.


Each subject was given either two tablets of Testofen, totaling 600 mg/day, or a placebo. Men taking Testofen scored higher on measures and reports on their libido, as well as increases to their sexual arousal. Most men reported a positive influence on their orgasms, as well.


Furthermore, Testofen resulted in men reporting increased satisfaction with their strength, their energy levels, and their overall well-being. The study concluded that Testofen is effective for helping to improve libido and could be useful for maintaining optimum testosterone levels.

HOW D-ASPARTIC ACID INCREASES TESTOSTERONE LEVELS

There is evidence that suggests D-aspartic acid increases testosterone levels. D-aspartic acid is an amino acid that can be found in the tissues of our hormonal (endocrine) system, and is linked to an increase in the amount of luteinizing hormone (LH) and testosterone.

One study followed a group of 23 men who were each given a dose of D-aspartate on a daily basis for a course of 12 days. The control group of 20 men was given a placebo. Following this, the amount of LH and testosterone built up in the tissues of the subjects were observed.

D-aspartic acid directly stimulated the release of both hormones, LH and testosterone. The study concluded that D-aspartic acid has an important role in helping to regulate and aid in the creation of both of these important hormones.

HOW SELECTED HERBAL EXTRACTS IMPROVE EXERCISE PERFORMANCE

There are lots of herbal supplements that have been touted to help people improve the results of their exercise. Unfortunately, not all of these have withstood the test of scientific observation. 

Many herbs, however, have. One study has evaluated a number of herbs that are commonly used to improve athletic performance, regardless of whether or not science has proven them to be effective yet.

Some of the herbs that are commonly used regardless of evidence include: the various ginsengs (American, Korean, Chinese, and Siberian), ma huang, ashwagandha, rhodiola, yohimbe, cordyceps, shilajit, smilax, wild oats, muira puama, saw palmetto, and wild yams.

The paper goes on to recognize that most of the Asian ginsengs have actually been quite reliable for improving exercise performance, given that people were using extracts of the roots for more than 8 weeks, taking at least a gram of the dried root or an extracted equivalent.

The paper continues to observe that Siberian ginseng did not provide reliable or significant improvements, and that mahuang does not currently show any scientifically significant improvement to exercise results.

Most of the other herbs, the paper says, remain untested despite many people reporting a positive improvement to their exercise performance when using them.
