does not boost exercise performance, what do they mean by that statement exactly?
Bloated GH Gut - Low Dose Not the Cause
The cause of a bloated gut in bodybuilding has long been attributed to growth hormone excess and enhanced insulin resistance, enlargement of the intestines and other organs. Many bodybuilders use growth hormone (GH) to enhance fat loss and enhance lean body mass. A study recently published in Growth Hormone and IGF-1 Research (subjects aged 17-20) found that a six-week, randomized and double-blind, placebo-controlled study of low-dose GH (starting dose at 2/ug/kg per day versus placebo in 15 abdominally obese men) decreased abdominal adipocyte size, compared to the placebo. The realization that “more is better” when it comes to growth hormone is when bodybuilders are looking to improve body composition, but “upping the dose” is not the best course of action!
Some bodybuilders use growth hormone (GH) to gain a competitive edge, but what are the real benefits? A study recently published in Growth Hormone & IGF Research found that GH administration elicits significant positive changes in body composition, but does not boost exercise performance.
Growth hormone is a controversial anti-aging drug. Some doctors prescribe GH to restore youth and improve lean body mass. This approach may have its shortcomings. New research published in the Journal of Science Advances suggests low levels of GH may help you live longer. Dr. Nir Barzilai, a geneticist at Albert Einstein College of Medicine in New York, said if “you want to live longer, it might be a better idea to keep growth hormone levels low, not try and raise them.”
In fact, low-dose growth hormone is being tested in a two-year study funded by billionaire-owner of the Dallas Mavericks and “Shark Tank” host, Mark Cuban, at the University of Michigan to save athletic careers. The theory is that growth hormone may be able to speed up recovery from career-ending ACL injuries.
However, high doses of GH used by many bodybuilders could cause the medical condition known as acromegaly — in which excessive growth hormone is present in the body, causing distention of the organs like the hands, jaw, liver, intestines and feet. When bodybuilders abuse GH, it can have disastrous effects— one of them being the horrendous GH gut. The growth of the “GH belly” is the fault of internal organs like the intestines and liver becoming enlarged and distended. Diabetes and insulin resistance are often the result of using high dosages of growth hormone. Bodybuilders sometimes experience short-term increases in blood sugar levels, possibly suggesting an increased risk of type 2 diabetes.
When high doses of GH are combined with insulin, especially fast-acting insulin, it makes the GH gut worse and negates the positive benefits of low-dose GH. Long-term treatment of insulin is linked to weight gain and fat storage. Worse, many of these conditions from high-dose GH abuse are irreversible, such as facial features becoming elongated and misshapen. The V-shape of the abdomen disappears and is now replaced by a distended belly, or bloated GH gut. When going off GH, internal organs may return to their original size, but facial changes and elongated hands and feet are permanent.
