Below are the main ingredients in the supplement:

Tribulus Terrestis
This is an annual plant that grows mainly in dry climate. It has been seen to reduce cholesterol and regulate blood sugar. This plant boosts energy which allows for a longer, more productive work out.1

Fenugreek is a popular herb known for its many health benefits. Available evidence shows that it can boost testosterone and lower blood sugar levels. It also helps lower cholesterol and thus plays a huge role in fat burning.3
L- Arginine
This amino acid is important in synthesizing proteins in the body. It also helps improve blood flow in the body, including to the penis. More blood flow results in bigger erections for better sexual performance.4

Caffeine is used to stimulate the central nervous system. It increases alertness and makes one feel more energetic. This drug can be useful in boosting energy e.g. during a workout but has no direct impact on testosterone levels.

This is one of the better ingredients in this blend at it contains loads of zinc. Zinc is widely used in most testosterone supplements as it helps the body to produce testosterone. It does this by helping the body to produce the luteinizing hormone (LH). LH is the hormone that notifies the testes to produce testosterone. Increased zinc levels boost LH production, and in turn more testosterone is made.

Schisandra Fruit
Schisandra fruit or the five flavor berry has many health benefits. It is a popular ‘adaptogen’ meaning it helps the body to resist physical and mental stress.
