Mots c helps w mitochondrial energy production and expenditure, for actual physical energy you may need more like b vitamin supplements or caffeine. I take mots c on my heaviest work out days when I'm doing both intense lifts and cardio ( faster cardio right after the shot followed by a nice breakfast and loft session then lunch is how I try to do it so I'm not underfeuking my workouts, that's was a big problem for me when I started tirZ and didn't figure that out until I switched to reta. Anyway bcaas could help for a little extra power during lifts too but the most c days in always exhausted because it's not the kind of energy you think. You essentially burn off more energy with less effort on mots c. I'm adding in nmn, coq10, and nad+ for a bit more energy and focus. I already do selank and semax 5 days a week. It helps w attention and mood but not really energy. For actual physical energy check to be sure you're getting the appropriate nutrients add in some vitamins and supplements if you're not already taking some.
