LOL same shit was written on the label, but i was so WANTING TO TAKE IT FASTER AND NO READ SHIT OF THE LABEL. So i just read till "over 90kg takes 18g" hehe.
Thanks, took 4 scoops. Was doing legs, so it felt more energy, i needed to rest less, and ofcourse after legworkout had a killer cardio workout on a treadmill, had to stop after 15mins did not feel very tired, but i was feeling my heart will explode, not bad not bad, had a minor crash after the workout, but all good.

P.S.: My back is still cramped, but not doing squats or any other stupid shit exercise that involves a lot of lower back action. And trying not to put to much weights in my hands when standing or doing shoulders, so its all good and ofcourse doing more ab workout, read that this is the main treatment because of disbalanced muscles. Before the injure never done abs for like 2 years.
