At higher HGH dosages, it is possible to achieve levels similar to those found in the endocrine disease acromegaly, which is caused by too much growth hormone in the body. This condition can lead to severe muscle weakness and even heart disease.
According to Dr. Rogol, perhaps the most insidious off-label use is by athletes and others who believe they are using actual growth hormone, when in fact they may be receiving an entirely different substance.
These compounds falsely sold as HGH may contain other unlisted ingredients, including anabolic steroid hormones or steroid precursors, which have been found to promote the growth of tumors. These unlisted ingredients can also appear in unknown quantities, while the entire preparation is of unknown purity.
In addition, the vast majority of clinically administered growth hormone is made by recombinant DNA techniques and not from human tissue. “Growth hormone made from human tissue has largely been removed from the market because of the rare but fatal Creutzfeldt-Jakob disease,” said Dr. Rogol. “Some of the HGH now available clandestinely is of human origin and may carry this deadly biological agent.”
By the sounds of these possible side effects, I would say it is not worth it! Good old fashioned diet, exercise and body building without the aid of drugs is always the best way to go.
