Why Choose TESTOLYZE™?

Testolyze is a natural and effective way to help you to increase your testosterone levels and inhibit estrogen production. These changes within the body result in an enhanced physique, with lowered body-fat and increased lean muscle mass, due to the anabolic effects of higher testosterone levels. There are over 10 different ingredients to help promote these changes in Testolyze which include maca, tribulus terrestris and d-aspartic acid.

When to Take TESTOLYZE™

Testolyze can be taken all year-round, but it is best to cycle this as continuous use will diminish the effects of it. Due to its benefits for fat loss and muscle building, it can assist when trying to lose weight or when you are looking to increase lean muscle.


Testolyze is a uniquely formulated testosterone booster to increase the natural production of testosterone in the body. It contains ingredients that have displayed this desired effect in clinical studies and provides a host of different ingredients to lower estrogen levels and raise your testosterone levels through the roof.


You can expect to see an increase in strength and muscle mass and a reduction in body fat from the anabolic effects of the raised testosterone levels within 1-2 weeks. The estrogen suppression and testosterone increasing properties of Testolyze will allow you to undertake a complete change in body composition and take your performance in the gym to the next level.

Myriad of Ingredients

There are a great number of ingredients that will help you to achieve these effects - from natural minerals such as zinc and vitamin b6 to natural testosterone boosters such as maca, saw palmetto and Tribulus Terrestris. A couple of these ingredients are reviewed and discussed below.

Tribulus Terrestris

Tribulus Terrestris contains flavonoids, amino acids, flavonol glycosides, steroidal saponins and alkaloids. It is commonly used as a testosterone booster and aphrodisiac among athletes and also provides diuretic, immunomodulatory, anti-diabetic, anti-inflammatory and anti-hypertensive properties.

Tribulus Terrestris is a natural and effective way to boost your testosterone levels. Although there is no agreement on the specific mechanism that results in its effects, it’s been used for many centuries across the globe and is a popular herb used for its aphrodisiac and libido enhancing properties. It can also act as an ergogenic aid, with studies showing it to increase muscle power, alleviate muscle damage and enhance anaerobic performance.

Studies researching the effects of Tribulus Terrestris on athletic performance in human participants have shown promising results. One study among trained male boxers found it to alleviate muscle damage and enhance anaerobic performance. Another study among young males showed it to significantly increase muscular power and blood testosterone after just 20 days of supplementation. These two studies support the ergogenic potential of Tribulus Terrestris and display its benefits beyond its ability to increase testosterone levels.

D-Aspartic Acid

This is an endogenous amino acid that is present in many tissues and cells of both invertebrates and vertebrates. It is more commonly found in endocrine systems, especially those that are associated with the reproductive system such as the adrenal gland, pineal gland, pituitary gland and testes, where it increases during adult life.

D-aspartic acid plays a key role in the biosynthesis and secretion of hormones in the endocrine glands. It increases gonadotropin-releasing hormone, increases the mRNA and protein levels of steroidogenic acute regulatory protein, has an influence on steroidogenesis by increasing the expression of subunits of NMDA receptors in the testes and induces up-regulation of androgen receptor and down-regulation of estrogen receptor expression.
