Before I start, I should tell you that I am not the most qualified to comment on this matter because I am not a doctor. My opinion on what is in a product is based on many years of experience, including being the medical director for the International Association of Clinical Endocrinologists. Most people want to buy supplements with higher testosterone, but don't know what they are supposed to do for them. I don't have any training or experience on this topic, so I don't know what is the best way to supplement testosterone. The other thing I would like to warn you is that some of the products that I am reviewing, such as the following, can cause side effects. If you are a woman and want to use a product, please discuss it with your doctor or a pharmacist. Here is a list of all the testosterone products I have reviewed. As you can see, there are many different products. For this reason, it is very important to read the label of each product to make sure that it is going to help your body and not cause side effects. It is also important to know the dosage for each product.
