As a (former) low-T guy who has benefitted greatly from Rebecca's help over the last two years, I can only give an enthusiastic five stars to this excellently written, easy to follow guide. On my journey to get my T back under control, I saw doctors who didn't really have a clue, a specialty clinic that wanted to greatly over charge me, and a local expert who would do part of the appropriate treatment but not all of it. With Rebecca's input I found a doc who knows what he's doing, and was able to advocate for myself throughout this whole process. The impact on my health has been phenomenal...more energy, motivation, and drive. And you wouldn't believe how good it's been for my marriage. And the long term health impact is huge as well. Guys...this could be the one thing you do for yourself and your marriage that makes all the difference. Wives...do this for your guy...and do it for yourself. It works.
