    Tastes and smell unbelievable horrible!

    The taste is unbearable, I tried mixing it with juices, water, everything, still have to hold my nose, chug it down and rinse my mouth with whatever I can find afterwards.

    Thanks for your feedback!

    Great stuff for a number of things

    I mix this arginine powder with lysine powder, which you are suppose to use with it anyway, as arginine uses up lysine, which is also necessary as one of the ingredients needed to produce the human growth hormone. Arginine turned my hair from grey back to blonde! Since lysine is sweet, if you also use a little l-glycine powder in with it, it makes the arginine much more palatable. It's not nasty at all!!! (:

    Digestion problem occurs

    Posted by iHerb Customer on Nov 04, 2017 | Verified Purchase

    Tablet formed L-Arginine works really well, so I assumed the powder form would even perform better than tablets, because powder would be a lot faster and easier to be absorbed. However, I couldn't figure out why It leads me to have diarrhea. It is not a very serious one, but still bothering symptom. Also it is a very common side effect of L-Arginine as I know. So I assume there is a case that a person who only goes along with tablet from of L-Arginine rather than powder form. I have tried to reduce amount of the powder, but it only lessens the seriousness of the diarrhea, not totally getting away from it. So I would like to recommend to but this product with the other mates and test in between 3 or 4 people and again the tablet works does not mean powder works too.

    Thanks for your feedback!
