Testosterone is a critical element of staying healthy.  Men and women alike need to keep their testosterone levels within a healthy range to promote muscle growth, protect bone health, enhance sexual desire, energy, and mood, and promote a healthy nervous system.

But, I wasn't surprised to read that 1 in 4 men have low testosterone.

Low testosterone can indicate androgen deficiency if it is accompanied by low sex drive, erectile dysfunction, osteoporosis or fracture, and two or more of the following: sleep disturbance, depressed mood, lethargy or diminished physical performance...

The future is not looking too pretty either:

...the researchers predict that by 2025 there may be as many as 6.5 million American men between 30 and 79 years of age with symptomatic androgen deficiency, an increase of 38 percent from the year 2000 population estimates.

I see these symptoms in people everywhere, quite often due to a lack of exercise and poor food choices. 

A great way to elevate your testosterone is to hit the gym with intense exercise and eat healthy whole foods everyday. 

Do not supplement with steroids, both over-the-counter and illegal steroids are detrimental to your health, your longevity, and exhibit horrible side effects.  Instead, get your hormone levels checked by a physician, see how your body is measuring up and discuss the results with him.
