It is possible, in fact, that many players who use steroids are not noticeably improving their performance as a result. muscle gain Steroids-from-mexico. There are more than 600 different types of steroids, but it's testosterone, the male sex hormone, that's most relevant to athletics. Testosterone has an androgenic, or masculinizing, function and an anabolic, or tissue-building, function. It's the second set of effects that attracts athletes, who take testosterone to increase their muscle mass and strength and decrease their body fat. muscle gain Apple cider vinegar diet. When testosterone is combined with a rigorous weight-training regimen, spectacular gains in size and power can result. The allure is obvious, but there are risks as well. Health EffectsAnecdotal accounts of harrowing side effects are not hard to find -- everything from "'roid rage" to sketchy rumors of a female East German swimmer forced to undergo a sex change operation because of the irreversible effects of excess testosterone. muscle gain Womens bodybuilding. But there are problems with the research that undergirds many of these claims. The media give the impression that there's something inevitably Faustian about taking anabolics -- that gains in the present will undoubtedly exact a price in the future. Christopher Caldwell, writing recently in The Wall Street Journal, proclaimed, "Doctors are unanimous that [anabolic steroids] increase the risk of heart disease, and of liver, kidney, prostate and testicular cancer. "This is false. "We know steroids can be used with a reasonable measure of safety," says Charles Yesalis, a Penn State epidemiologist, steroid researcher for more than 25 years, and author of the 1998 book The Steroids Game. "We know this because they're used in medicine all the time, just not to enhance body image or improve athletic performance. " Yesalis notes that steroids were first used for medical purposes in the 1930s, some three decades before the current exacting standards of the Food and Drug Administration (FDA) were in place. Even so, anabolic steroids or their derivatives are commonly used to treat breast cancer and androgen deficiencies and to promote red blood cell production. They are also used in emerging anti-aging therapies and to treat surgical or cancer patients with damaged muscle tissue. Caldwell cites one of the most common fears: that anabolics cause liver cancer. There is dubious evidence linking oral anabolics to liver tumors, but athletes rarely take steroids in liquid suspension form. Users almost uniformly opt for the injectable or topical alternatives, which have chemical structures that aren't noxious to the liver. And as Yesalis observes, even oral steroids aren't causally linked to cancer; instead, some evidence associates them with benign liver tumors. More specifically, it's C-17 alkylated oral steroids that are perhaps detrimental to liver function. But the evidence is equivocal at best. A 1990 computer-assisted study of all existing medical literature found but three cases of steroid-associated liver tumors. Of those three cases, one subject had been taking outrageously large doses of C-17 oral anabolics without cessation for five years, and a second case was more indicative of classic liver malignancy. It's also C-17 orals, and not other forms of steroids, that are associated with decreased levels of HDL, or "good" cholesterol.
