Improved sleep quality is almost inarguable when discussing GH use.

What I dont understand is how does this occur?

For the majority of users, GH is used in the AM. Not only does this exogenous introduction of GH interfere with natty GH release at night, the exo-GH life has expired in large part by the time you hit the sack hasnt it? ALL 2-3IU's that were injected in the AM have already been used up no? If so - what exactly is helping you get this deep/quality sleep?
