This page is an overview of testosterone replacement therapies. The following products are for people who are in their mid-to-late 40s, but are also at the end of their cycle and have low levels of testosterone, including men who have a history of heart disease. I'm not the only one who is reviewing products for testosterone. Several companies are doing the same. The only difference between these products is the dose of testosterone. That said, all of these products, at least as of this writing, have some degree of certainty that they work for people with testosterone deficiency. These products are not "generic." This means they are not the same as the drugs that the FDA has approved. They are not available over the counter. They are not interchangeable. I don't recommend using them. These products don't work for everyone. You are at your own risk. If you are a man who needs testosterone supplements to help with your low testosterone, I will recommend that you check out my guide to testosterone and your doctor's advice. Now, here's how I would recommend you go about it. I would not recommend the testosterone pills. That's where I have been seeing the most complaints from people, and it's not the testosterone pills.
