To be honest, I would not be surprised to learn that they had experienced difficulties getting published in an actual peer-reviewed journal. Traditionally the value of a product is determined by a large, double-blind, placebo-based clinical study. Not only can this be very expensive and cost-prohibitive for smaller independent companies, but getting the large pharmaceutical firms involved is almost impossible without proper incentive (read, monetary gain). They will certainly not invest millions of their own dollars on a trial when there is no benefit to themselves. This unfortunately is often the case when it comes to non-prescription based medicines and therapies, particularly those pertaining to "male enhancement."

Aside from these stumbling blocks, the medical industry itself sometimes seems at odds with the very practices they espouse. One recent article even suggests that pharmaceutical giant Pfizer actively suppressed a clinical study when the findings did not suit them. Although this case is still pending, I seriously doubt any substantial repercussions will result.

There have of course been some published studies involving natural male enhancement therapies that managed to get through the "red tape." You will need to thoroughly read this report since the actual mention is surreptitious – it focuses mainly on this treatment as a method for correcting penile curvature with a brief remark regarding "increased penile length." I wrote an article discussing these findings here:

Study Confirms Penis Extender Effectiveness

When it comes to legitimate natural enhancement/enlargement methods, we are all at some point required to rely on the testimonials of others. This is inevitable even with sites such as ours that conduct product reviews and perform research about the companies behind these solutions. We have however made it mandatory that all included products and services come backed with a solid guarantee of effectiveness (a 6 month minimum for our top recommendations). This ensures that customers have an adequate time period to evaluate a product and, if necessary, receive reimbursement if not entirely satisfied.

I would like to apologize for the lengthiness of my reply. I merely wanted to convey that the information included on our website is not haphazardly compiled without first undergoing some research. Thank you for your time Kevin. If you have any additional questions, please do not hesitate to contact us.
