Based on the general idea and concept - which looked good on paper - you would think that by entering intensive sleep much quicker and thus shortening (or skipping depending on which version you believe) the 1st stage sleep phase (shorten) and 2nd stage sleep phase (skipping), you would spend more time in 3rd - 4th stage sleep phase where GH is said to be secreted predominantly during these stages than others.
Most common example was to say if you slept 8 hours per night and 30% of that time was spent in the primary GH releasing phases, (rest of time consisted of getting sleepy, falling asleep, entering deep sleep and awakening) then GHB would help you bypass the first two stages and enter deep sleep much faster. So you reduced the time of the first two stages and added it to 3rd and 4th stage phase. People claimed now you got 8 hours sleep per night and spent 50% (or more) of that time in GH releasing phases and thus got more GH released that you could use for growing and such.
Well, now as it was then, the truth to that is highly debatable. In the experience I had with it, it definately did make me go to sleep faster and sleep harder. However, I slept shorter times as well. Instead of sleeping 8 hours at 32% of the time in later sleep stages, I spend the same amount of time in those phases ( that the 32% was based on), but just woke up sooner. I found that using GHB I only needed about 6.5 hours before waking up refreshed. So it sort of balanced out overall. Which was not a good enough boost to risk addiction to it just to save a bit of time.
I never hear of bodybuilders using it nowdays. Only people getting high and such.
