Hi gkhchay,
is GABA can be purchase from GNC or must order online?
I haven't bought fr GNC for ages - their prices are exorbitant compared to the local & US online supplement stores..
With the exception of Whey protein which I get fr the local online supplements stores & Tongkat Ali (v good testosterone booster at only $20 per bottle) fr either Guardian or Watsons, all my other supplements I order from iHerb, which has got a very wide selection. Even with the shipping charges thrown in, it's only a fraction of what you pay at GNC, Natures Farm or any local supplement store...
