Zyrexin is made in the U.S. by Superbalife International, a well established nutraceutical manufacturer. According to the product website, Zyrexin has been formulated to work within 35 minutes and whose effects are claimed to last up to 24 hours. Unfortunately Superbalife International actually provides very little product information about Zyrexin; there is no reference to any scientific data from clinical studies whose research would verify any of the product’s claims and no ingredient information, which is inexcusable.
The manufacturer of Zyrexin did not include any ingredient information on the product website, apart from stating it contains Superba Butea, a substance commonly found in enhancement products; why any enhancement company would believe that consumers would be willing to ingest any product whose contents are completely unknown to them, is baffling.
It’s therefore impossible to determine the effectiveness of the product based on the limited information on the Zyrexin website.
Customer reviews on the Zyrexin website feature audio recordings of supposedly real users of the product, who enthusiastically endorse its abilities to restore normal sexual function, enhance sexual desire, produce stable, lasting erections and improve sexual stamina.
QUALITY OF INGREDIENTS
Our research discovered that Zyrexin contains two critical ingredients scientifically proven to be essential for the success of male enhancement products, Horny Goat Weed/Epimedium and L-Arginine. It also contains GABA Gamma Amino Butyric Acid), a substance commonly featured in enhancers. We saw no indication of the quantities of any of the substances in Zyrexin however, which makes it very tough to gauge their effectiveness.
More troubling by far is that Zyrexin also contains Yohimbe, a substance made from the bark of a West African tree by the same name; it’s also known by its active ingredient Yohimbine, which can be laboratory synthesized. Many male enhancers feature Yohimbe, claiming it has been used by men in the region for centuries as an aphrodisiac.
However the FDA has flagged Yohimbe as a substance of concern and it has been banned in many nations around the world due to its alarming history of causing numerous adverse health conditions, including headaches, dizziness, anxiety, insomnia, hallucinations, hypertension, seizures and kidney failure.
We strongly warn consumers against the use of any enhancement product which features Yohimbe, including in this case, Zyrexin.
The ‘Starter package’ of 2 small bottles of Zyrexin (10 capsules each) is available from the product website for $29.95, fairly reasonable for male enhancers.
The product is covered by a 60 day money back guarantee.
We will never endorse any male enhancement product which features Yohimbe, because no matter what any manufacturer may claim, this substance is simply not safe for human consumption, and its inclusion in any enhancement formula is an automatic disqualifier for legitimacy.
We therefore cannot recommend Zyrexin as a safe or effective treatment for erectile dysfunction.
