I do have a lot of products. I am using some of them as I write this, because I'm a medical doctor. I know how to keep and maintain the effectiveness of many products. I will also be adding products that have more staying power that I don't recommend. This page is very comprehensive, and the main reason I wrote it is to help other people as well.
For more information on the topic, check out The Health and Diet of Men and The Men's Health Resource. The products I am reviewing are from various sources. Please don't hesitate to ask me any questions you have. As a medical doctor, I'm also very interested in how these products work, why they work, and if they are safe for the user to use. I would also recommend that you visit the men's health resource, and check out their website, for information about the topic. The reviews I've been reading are mostly from men, so I have a feeling that this may be somewhat common knowledge for most people, but still needs to be emphasized. The following companies make products for men. I have also included their websites, as well as links to their Facebook pages, so you can check out the product themselves, their marketing materials, and their testimonials.
