This guide has come out as a final outcome of my work in the sale of potency enhancers and ED medications, as well as from my personal interest in supplementation products. During one very recent period of my life, that's what I've been doing for the vast majority of my time; it was my source of income, and my great passion. What I have noticed (and it didn't seem strange to me at that time) was how little people actually knew about something that was so important to them, whether they were willing to admit it or not. Unfortunately, what I've been doing was also illegal, so I was forced to stop my activity. And yet fortunately, that gave me the idea to write this guide and share with others everything that I have learned when I was active in the business, and to help an even greater (actually, much, much greater) number of people, all over the world. Since this is a topic of a great interest to a vast number of people, potentially shameful to talk about openly, and also in a certain legal "grey zone," it's no wonder that people are so often misinformed and make some very wrong and costly choices. The focus of the book is on the basic and accurate information you are ever going to need on this topic; that approach extends through the entire guide, and is, as I have noted, based on the real life experience. It begins with the causes of the need to use the erectile dysfunction medications and potency enhancement products; you'll find out some quite interesting facts there. After that you'll find about which ones actually work and which don't, backed by scientific research (matching my own experience). You'll also learn about how to take them and how strong they act, along with the common information on the onset of action and duration, dosing and the side effects. I further added some information about some of them which have an effect on fertility, or act as female aphrodisiacs as well. The following chapter contains some basic facts about combining them, and about combining them with some other frequently used substances and with the effects of these substances on potency. And the last, but perhaps the most important of all- the purchase. You'll find out all about the kind of products you should avoid, and about the best ways to obtain the ones with the capacity to make your sex life skyrocket.
