Neuroactive steroids are also called as neurosteroids . They are endogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors. Neuroactive steroid refers to steroids that are synthesized by an endocrine gland that reach the brain through the bloodstream and have effects on brain function. Neurosteroids have a wide range of potential clinical applications from sedation to treatment of epilepsy and traumatic brain injury. Ganaxolone is a synthetic analog of the endogenous neurosteroid. Allopregnanolone is under investigation for the treatment of epilepsy.
The Drug Enforcement Administration of the US Department of Justice considers off-label prescribing of HGH to be illegal, and to be a key path for illicit distribution of HGH.  The FDA, as recently as 2012, has issued alerts stating that "FDA-approved HGH can be legally prescribed for a limited number of conditions."  The FDA and the Department of Justice have shut down companies and compounding pharmacies that have marketed HGH for off-label purposes - especially for bodybuilding and anti-aging uses.   And some articles in the popular press, such as those criticizing the pharmaceutical industry for marketing drugs for off-label use (which is clearly illegal) have made strong statements about whether doctors can prescribe HGH off-label: "Unlike other prescription drugs, HGH may be prescribed only for specific uses. sales are limited by law to treat a rare growth defect in children and a handful of uncommon conditions like short bowel syndrome or Prader-Willi syndrome, a congenital disease that causes reduced muscle tone and a lack of hormones in sex glands."
