Training late after work used to drain me—then I started using VO3. I’m still hitting full-speed in the 10pm BJJ sessions, and come Sunday I’m recovering smoother than ever. Zero sleep disruption.

I split my week between heavy lifting sessions and endurance runs, so I need something that supports both. VO3 gives me that extra push on the weights and keeps my legs from burning out on long runs. No jitters, no crash — just clean performance I can actually feel.

CrossFit workouts hit every energy system, and VO3 helps me stay consistent through it all. I feel more endurance during metcons, faster recovery between sets, and I don’t get that wired feeling afterward. It’s clean, simple, and actually works. I take it before every session now.

I log anywhere from 40 to 60 miles a week, and VO3 has made a noticeable difference in how I feel during and after long runs. My breathing feels smoother, my legs don’t hit that wall as early, and recovery time has shortened. No caffeine, no crash, just steady energy that keeps me moving.
