Gnc Pro Performance L-Glutamine Powder, Unflavored

Pros: affordable unflavored pure hydrates cells
Cons: no immediate results/benefit small long-term results/benefit

Glutamine has always been the bodybuilder's prefered amino acid and as a supplement it has stood the test of time as 99% of supplements have come and gone off the GNC shelves.
The basic pure version from GNC is relatively inexpensive, it is unflavored, and is has some benefits, but nothing exeptional. The promise is that it boosts growth hormone, keeps you healthy, super hydrates your cells, and fight catabolism. The reality is that a lack of glutamine will lower growth hormone levels so it does not raise your growth hormone levels unless they are lower than normal for some reason. It does hydrate your cells a bit so your muscles feel fuller, but not nearly to the same effect as creatine. All in all, it's worth supplementing with if you have all your other basics covered and want to use some more. This is an affordable no-thrills brand.
