This is the best bcaa, which I accepted. I buy for six months. Banks are enough for a month. Drink in the morning on an empty stomach one teaspoon. and one spoon for 15 minutes before a workout. twice muscles recover faster. Always raised tone. Adds endurance training. Buy, do not regret. I tried several other companies - but there was no such effect. And yes, you feel the effect, in a week, that is not right. If my review was useful to you - vote!
