Good at raising GH levels standalone?
It is but this isn't the real question..
The real question is, will using GABA lend itself to greater/faster increases in LBM and/or fat loss? My experience has been....indirectly. It provides very sound sleep and deeper REM sleep for most. Cheap, effective adjunct to your recovery toolbox.
Just don't bank on the GH release to be the driver.
