Studies demonstrate protection against diabetes, obesity, cardiovascular disease, kidney disease, liver disease, neurodegeneration, and cancer through comprehensive metabolic optimization
Research in humans is a bit less impressive Clinical trials in humans A 1981 double-blind study found that chronic insomniac patients found that subjects slept 59% more, shorter sleep latency, and higher sleep efficiency (Schneider 1981) A 1987 double-blind study did not find any statistically significant changes in sleep structure as measured by REM sleep, NREM sleep, or total sleep time (Debellis 1987) A 1992 double-blind study in 14 chronic insomnia patients found higher sleep efficiency and subjectively estimated tiredness decreased to similar levels of healthy subjects in 7 nights of injections (Schneider 1992) There are some limitations to these studies however
The process will take about 2-4 hours, and can be done on an outpatient basis
On a bell curve, an increase that produces less effect is ambiguous: you cannot tell whether you are below the peak or past it
