When your body has enough testosterone, the brain does not send the LH signal to your testicles. Therefore, you will not make any testosterone until your levels drop to below normal and the signal returns, stimulating production. Since you are getting testosterone from an outside source, your brain is most likely not sending that signal to your testicles. Over time, the old adage of “use it or lose it” comes into play and your testicles will shrink in size. The time is different for every man and the amount of “shrinkage” is different for every man. Fortunately, the HCG will quickly restore the size and function.
Also...when you are on testosterone therapy, it is inevitable that your cholesterol level will go up. Cholesterol is the beginning chemical structure for many of our hormones. The enzyme that begins the changes of cholesterol into other hormones is stimulated by LH. When taking testosterone, LH is suppressed. When you inject the HCG, the enzyme is stimulated again and the pathway flows normally.
So...using HCG while taking testosterone is important to maintain testicular size and function, help balance the other hormones needed in the body, and increases a man’s sense of well-being and libido.
I recommend 500IU three times a week, one week on, three weeks off. Inject the HCG during the first week of each month.
