This product has been climbing up the charts in the last six months as I continue to hear and see extremely positive reports on the results guys are getting with it. The name Xantho 5X (pronounced –Zan-Thoo) comes from the herb Xanthoparmelia Scabrosa. This herb was first used in Herbal V and it produced great results. Since 2005 there have been stronger and stronger extracts of Xanthoparmelia Scabrosa being produced and this product seems to have the strongest potency – BY FAR! The Xantho 5x formula is very comprehensive and well rounded. It consists of 15 different ingredients. Some of the most important compounds in the formula are Cnidium Monnieri, L-Arginine HCL, and Avena Sativa. The Cnidium Monnieri is a very high potency form from Europe and has been shown in clinical trials to increase testosterone production. The Cnidium Monnieri comes from the most active part of the plant known as the "Osthole" section. It is the most expensive and most active and beneficial section of the plant and leads to greater vasodilation. The company has also invented a technology called Vaso Expansion Technology, which targets the two chambers of your penis in a way that allows for greater expansion of your capillaries. This helps to enhance vasodilation, which is always a good thing! The company also gets high marks for their superior customer service and manufacturing practices. Some of the companies are often on a "back-order" status because their products sell out or they do not have sufficient inventory. This company has a massive production facility and is able to keep up with demand quite well. Companies studies indicate that best results are noticed when on their three-month program. Additionally, you may also experience harder and fuller erections which can also make your sex life much more pleasurable. Excellent product that has made improvements to its formula and it is paying off big time! Grade A-
