GHB are the abbrivations of Gamma Hydroxy Butryaat, also called ”Liquid XTC” or just “X”. But GHB has nothing to do with XTC. Initially the drug was developed as an anestheticum in 1960. The use as a narcosis means has strongly been decreased in the meanwhile, because there are many better resources at the present time. Also the substance was used as a means against insomnia or other sleepimpairments, as appliances at labour and to treat alcoholic abstention phenomena. In animal experimentings GHB had shown to be involveded in the production of Growth Hormone, and that their levels increased during administration, and this draw attention of bodybuilders. Allready soon it became the nickname “growth hormone booster”. Until now no scientific proof has been delivered that GHB raises growth hormone levels in human beings, nor that it prevents the muscle tissue breakdown. During the eighties and nineties GHB became popular at bodybuilders. GHB was a widely available over the counter supplement  until it was banned by the US FDA in 1990. The substance has many beneficial effects, but it was typical used by bodybuilders and athletes because it can significantly raise growth hormone levels. Unfortunately, the increase in GH levels is also accompanied by an increase in levels of prolactin. The increase in prolactin counteracts many of the positive effects of an elevated GH level. This probably explains why many athletes experience, very little as far as muscle growth with the use of GHB. Several athletes using GHB, report an increase in lean body mass and strength increase. Many users don’t experience any muscle or strength increase, but do feel GHB helps to accelerate fat loss.
