Men can now get quicker erections with the natural Viagra present in Still Bull Herbal Coffee, FDA warns it can be fatal.Reuters

Stiff Bull herbal coffee contains ingredients which help men in achieving a faster erection. The ingredients -- tongkat ali, maca root, and guarana -- contain natural Viagra which provokes natural stimulation at a faster rate. These natural stimulants have also been used by Asians and South Americans for centuries.

According to Daily Mail, more than 200,000 men have ordered this instant coffee within a month's time and the demand is soaring further.

A cup of this coffee will trigger hormone levels in men, leaving them energised, aroused and stimulating naturally. "It's almost like a fountain of youth for sex. It increases your stamina for sex and gives you energy, not just an erection," Stiff Bull's president Keith Hanson was quoted as saying by the Daily Mail.

"With Stiff Bull coffee it works with your body, enhances your body and your hormones," he added.

It has been found that maca root is the source of the energy. It boosts energy naturally and leaves the body feeling sexually aroused without producing any unnatural erection.

But scientists from the US Food and Drugs Administration (FDA) tested the coffee and found the presence of desmethyl carbodenafil. It is structurally similar to FDA-approved drug called Sildenafil, which is used to cure erectile dysfunction. This drug has the potential to fatally lower the heart rate of men consuming it.
