Tribulus Terrestris:

Tribulus terristris supports the production of testosterone in men. The best benefit of this herb is that it promotes the body’s own production of testosterone and does not act as a hormonal supplement. It also helps in  maintaining a balanced level of testosterone in the body thereby increasing the strength and muscular capacity of men. Tribulus terristris is one of the main herbs which is found most of the body building supplements.

There are many known history records that show beneficiaries of this wonderful herb from time immemorial. The herb was administered to men to provide them strength and vitality during their long journeys to fight battles. It was also used to enhance the sexual health of the men.

Maca herbs contain a mixture of minerals, proteins, amino acids, plant sterols and phytochemicals. The minerals, proteins and amino acids and plant sterols contribute to building muscle [lean mass] and a healthy body. Plant sterols are highly in demand for muscle building as they are natural products which do not have any side effects. The phytochemicals in Maca, some of which are only found in Maca make the herb an aphrodisiac and contribute to enhanced sexual performance.

Science behind Maca:
Asian Journal of Andrology. 2001; 3:301-303. The study was designed to determine the effect of a 4 month oral treatment with tablets of Lepidium meyenii (Maca) on seminal analysis in nine adult normal men aged 24-44 years old.

Methods used: Nine men received tablets of Maca (1500 or 3000 mg/day) for 4 months. Seminal analysis was performed according to guidelines of the World Health Organization (WHO).

Results of the research: Maca improved sperm production and sperm motility by mechanisms not related to LH, FSH, PRL, T and E2. [Source of this research:]


Sexual activity is all about blood flow to the right parts at the right time. The body needs nitic oxide to improve blood flow. L Arginine is a natural supplement which restores and enhances the production of nitric oxide in the body. As a result the blood flow increases and the pressure on the heart to pump blood throughout the body is taken off.
Poor penile blood flow results in poor penile strength which leads to erectile dysfunction. With L Arginine supplement the blood flow is restored to optimal levels and the healthy heart functioning helps gives increased stamina for enhanced sexual performance. While it gives short term benefit of increased stamina in sexual performance, you can enjoy good heart health in the long term.
