Tasteless, easy to swallow
I mix it with leucine and it works great. I will repeat the next time but in powder form.

Great
What I like is that each tablet is 1g, so if you need to take 4 or 5g you don't have to take as many tablets as with other brands.

Recovery.
We take it for climbing days, to recover better from one day to the next. I can't say that it is super effective, but it is true that if we forgot to take it the next day we felt more tired muscles. So it is not missing in our supplementation list.
L-arginina |
It is always in my nutrition.
For its quality-price you can not ask for more, those of us who are old school we like that touch that gives in training. It is a vasodilator, more blood to the muscles. So it gives you those pumps we all love. Zero liver damage and all natural. For me, 10 out of 10.

Ideal to complete your pre-workout.
If you are looking for a quality pre-workout, with a proven effect on nitric oxide, it works very well, if you combine it with a source of caffeine, it is ideal for this purpose.
