Thousands of middle-aged men use testosterone gels to increase blood testosterone levels. Hormone replacement therapy assists men in maintaining muscle and bone mass, improves mood, enhances metabolic health, prevents depression, and boosts sexual performance. Gels are often better than injections because they provide a more steady level of blood testosterone.
A study from the Center for Sexual Function/Endocrinology in Massachusetts, showed that applying testosterone gel to the arms and shoulders stimulated the production of higher blood testosterone levels than rubbing the gel on the chest, abdomen, or legs. The study examined middle-aged men with low blood testosterone levels (less than 300 nanograms per 100 ml). Applying the gel to the arms and shoulders increased testosterone above 500 mg, which is within the usual range for adult men. Testosterone levels were 20 percent less after rubbing the gel on other places. This is extremely significant information for men who use supplemental testosterone gels or creams.
