Let's look into the 3 main ingredients and what is known
D-Aspartic Acid
Aspartic acid, is an α-amino acid that is used in the biosynthesis of proteins. Similar to all other amino acids it contains an amino group and a carboxylic acid.
Testosterone is a well-known hormone that’s responsible for muscle building and libido. Because of this, people of all ages are looking for natural ways to increase this hormone.
One popular method is to take dietary supplements that may boost testosterone. These products often contain the amino acid D-aspartic acid.
D-aspartic acid can increase the release of a hormone in the brain that will ultimately result in testosterone production. It also plays a role in increasing testosterone production and release in the testicles, and these functions are reasons why D-aspartic acid is popular
Tribulus Terrestris
Tribulus terrestris is plant that's covered with spines. It is also called puncture vine. People use the fruit, leaf, or root of the tribulus plant as medicine. Some formulations also include other ingredients.
Used as a powerful sexual tonic, Tribulus tops the charts of herbal Viagra. Studies have shown that this herb elevates the luteinising hormone (LH), increasing the levels of free testosterone in healthy males.
This in turn could increase sexual desire and libido, and improve the quality of sperm whilst making it more nimble, in some cases it might help to remedy erectile dysfunction and it has been proven to be helpful in cases of premature ejaculation.
One of the main compounds of this herb is a phytochemical known as "protodioscin", with one study showing it helps to boost nitric oxide production.
Nitric Oxide is an essential element of an erection, enabling the smooth muscles of the penis to relax, allowing uninterrupted blood to flow to this area. Tribulus will stimulate the production of sex hormones without affecting other bodily systems.
As a bodybuilding or training supplement, Tribulus is hard to beat. It contains one steroidal saponin in particular – protodioscin – which is thought to be the active nutrient responsible for this herbs popularity amongst athletes.
Specifically, protodioscin promotes the release of nitric oxide which in turn increases the flow of oxygen rich blood to muscles, and enables better use of nutrients such as protein. At the same time protodioscin stimulates the pituitary gland resulting in it producing LH, thus promoting higher testosterone levels.
As well as contributing to a boost in testosterone levels, Tribulus Terrestris can also help to increase stamina during a workout as well as aiding post workout muscle recovery.
Fenugreek
Fenugreek is an herb similar to clover that is native to the Mediterranean region, southern Europe, and western Asia. The seeds are used in cooking, to make medicine, or to hide the taste of other medicine. Fenugreek seeds smell and taste somewhat like maple syrup. Fenugreek leaves are eaten in India as a vegetable.
Some men use fenugreek for hernia, erectile dysfunction (ED), male infertility, and other male problems. Both men and women use fenugreek to improve sexual interest.
