Since the quarantine I've been focused on running more. Im not the long distance running type more built for short sprints and bodybuilding. The very first day of trying PERFORM 6-IN-1 | NOOTROPIC PEAK PERFORMANCE was amazing. I noticed my legs did not fatigue as quickly, I also felt like I had more oxygen consumption which allowed me to run longer distance. My recovery time was still the same but I believe thats because I pushed myself to work harder. I'm definitely a fan of Perform! 5 stars.
