Most male sexual enhancement supplements on the market today offer a natural way to improve the firmness and duration of an erection as an alternative to prescription medications. There are not too many male enhancement supplements that claim to be capable of causing a permanent increase in penis size. Extenz-Rx is one such product.
Extenz-Rx is a supplement that makes some lofty claims. The Extenz-Rx website states that use of this product will “increase you penis length up to three to four inches and one inch in girth.” The site goes on to claim that “men who have used Extenz-Rx for three months have reported an increase in erection size and firmness of up to 33%.”
So how does Extenz-Rx do it? According to the product website, Extenz-Rx works through the exclusive use of Siales HCL. What is Siales HCL? That is never really adequately explained. Apparently, Siales HCL stimulates an increase in the blood flow to the penis during arousal. This increased blood flow “may” over time, result in larger and thicker erections. There are some other ingredients that might also help in treating the symptoms associated with erectile dysfunction. One prominent ingredient is yohimbe, is a derivative of the yohimbe evergreen of western Africa that has been used for centuries to treat impotence and had recently emerged as a popular additive to natural, herbal supplements used to treat erectile dysfunction. There is also maca, a Peruvian plant that reportedly increases libido, horny goat weed, and gingko biloba, among others.
The herbal components of Extenz-Rx are a good choice by the manufacturer as they all have been shown to have, in one way or another, a positive impact on male sexual performance. The product website does offer a 100% money back guarantee, as well as discreet shipping.
There is no herbal or prescription product that has been shown to increase the size of the penis. Many supplements contain products that have been reported to increase the blood flow to the penis, but don’t claim to increase size. It is therefore difficult to understand why the makers of Extenz-Rx would make such a leap. The faith they put in Sialis HCL is in no way founded upon any sort of medical research or clinical studies as presented on the website. Also, without any sort of research, the consumer cannot be completely assured that no side-effects are possible as a result of taking this product.
Without any sort of hard (so to speak) evidence to support the claims of penis enlargement, Extenz-Rx would ask the consumer to simply take the manufacturer at its word. That might be asking too much. Again, there is no holistic or prescription product that has been proven to increase the length and girth of a man’s penis. Should such a product become available, it goes without saying that it would be supported by actual medical evidence. It is this lack of any medical or clinical corroboration that causes Extenz-Rx to fall short.
