- Likely too light to matter
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
A clean 200mg caffeine dose, with modest, label-estimated amounts of betaine and beta-alanine — likely too light to deliver a meaningful strength or endurance effect on their own.
Honest take: The "performance" branding oversells it — this is just a decent energy drink with token amounts of a couple of extras.
