"Every man desires to live long," wrote Jonathan Swift, "but no man would be old." He was right, but the fountain of youth has proved illusory. And while more study is needed, GH does not appear to be either safe or effective for young athletes or healthy older men. But that doesn't mean you have to sit back and let Father Time peck away at you. Instead, use the time-tested combination of diet and exercise. Aim for a moderate protein intake of about .36 grams per pound of body weight; even big men don't need more than 65 grams (about 2 ounces) a day, though athletes and men recovering from illnesses or surgery might do well with about 20% more. Plan a balanced exercise regimen; aim for at least 30 minutes of moderate exercise, such as walking, a day, and be sure to add strength training two to three times a week to build muscle mass and strength. You'll reduce your risk of many chronic illnesses, enhance your vigor and enjoyment of life, and — it's true — slow the tick of the clock.

Are your hormones in tune? Mounting evidence suggests that exposure to light at night -- whether you're asleep or awake --  might play a crucial role in cancer, diabetes, and obesity. The World Health Organization classified "circadian disruption" as probably carcinogenic, and light at night is considered by some to be an endocrine disruptor that may affect melatonin, cortisol, ghrelin, leptin, and testosterone. "Most people think, and the drug companies want you to think, that waking up at night is bad for you," says Richard Stevens, ., a cancer epidemiologist at the University of Connecticut health center. But that's not the case, he says -- it's exposure to light at night that's the problem. "If you wake up at night, as most of us do, that is a period of quiet wakefulness -- stay in bed, in the dark, and enjoy it," Stevens suggests.

Dihydrotestosterone (DHT) (referred to as androstanolone or stanolone when used medically) can also be used in place of testosterone as an androgen. The availability of DHT is limited; it is not available in the United States or Canada, for instance, but it is available in certain European countries, including the United Kingdom , France , Spain , Belgium , Italy , and Luxembourg . [5] DHT is available in formulations including topical gel, buccal or sublingual tablets, and as esters in oil for intramuscular injection. [6] Relative to testosterone, and similarly to many synthetic AAS, DHT has the potential advantages of not being locally potentiated in so-called androgenic tissues that express 5α-reductase (as DHT is already 5α-reduced) and of not being aromatized into an estrogen (it is not a substrate for aromatase).
