Alpha XL Boost it is important to realize that a high testosterone level does not result in bigger muscles or better performance. Only a normal level of testosterone can accomplish this. When excess testosterone is detected by your body, it stops production of its own testosterone. It also turns the excess testosterone into DHT, which is responsible for baldness and leads to prostate problems. The body can also turn excess testosterone into estrogen, which is a female hormone, which can result in an appearance that a male bodybuilder definitely does not want. It does all of this, and you get absolutely zero bodybuilding rewards from it.
