This glutamine it repays pretty good, the effect is there repays, the muscle is regenerated much faster! One should not take it to be as it is constantly on the packaging! Important sublingual receptive by placing 1-2 teaspoons of the glutamine under the tongue and then waits for 1-2 minutes, or just longer -> depends on the saliva until it dissolves slowly, by an enzyme under tongue formed, that the inclusion of glutamine makes clear better! Let's say 50% of it is taken! This is great! If one does it, however, in the shaker into the glass or ... well then the majority reaches not even bother to go where it should, one probably 10% !!! So, please keep tuned! :) Just under 32 Euro are quite expensive ... for example you get the 500g at peak for just under 25 euros, but it's Frey! Frey is very expensive but it is a German manufacturer and the products are all high TOP! So I invest in these products also like BCAA, Malto, Protein 96 all highly recommended! The taste Oo .. which flavor is so I can see only that it even slightly sweet tastes wenns dissolves. Not at all uncomfortable, I find anyway. So the purity is good, as with all products with Frey.
Conclusion: Highly recommended, otherwise you should resort to such as Peak or Scitec.
