Hm for the glutamine acid I can fill in some of the blanks (only the positive ones here ;) ):
To me my (injured) ligs finally feel like they are really going to heal this time. Kinda like the effect of massive doses of Vitamin C, only with a more healed feeling than with Vit. C.
On second thought this is true for any injury I happened to inflict on myself in the last few days.. On a downside glutamine acid really affects my shortterm memory in a bad way (but my long term memory in a good way). There must be something I’m missing here obviously :)
