Zyrexin claims to work quickly with results that can last up to 24 hours. The manufacturers claim that there are no side effects although the official website lacks information about the ingredients that have been used to formulate the product. The only mention is of Butea Superba, which is an herb found in Thailand and known for its aphrodisiac properties. Why all the secrecy for a product they claim to be the "Sex Super Pill"?

On the other hand Irexis male enhancement lists all of its ingredients as well as the quantity of each found in every pill. Some of the potent ingredients incorporated in this formula include Muira Puama, Catuaba Bark, Oyster Extract, and Yohimbe Extract. The pills are manufactured in facilities that adhere with cGMP (current Good Manufacturing Practices) guidelines. Additionally, Irexis offers a risk free 90 day money back guarantee while Zyrexin's 100% Iron Clad money back guarantee is only good for 60 days.

Despite all its claims, Zyrexin fails in its primary responsibility of providing full disclosure to its clients. A discerning consumer would want to know what substances go into their system when consuming a male enhancement pill. Such a person would opt for Irexis which believes in being transparent about such matters then backs it up with a better guarantee.
