Yes I remember.
I started using Gaba/Gabob as my first pre-bed attempt to increase GH and sleep. In an older body you will notice the small bump in GH release.
Suffering from sleep apnea terribly at the time I noticed positive results about 2 months into it. That is what prompted me to take a look at better GH secretagogues.
It is inferior to the GHRH/GHRPs and less consistent and predictable (Gaba and the derivatives can be biphasic). Gabob is difficult to source. It is too closely related to a now illegal Gaba derivative GHB I suppose... even though it does not share the same effect.
