- Very high caffeine content
- Contains anxiety-risk stimulant, yohimbine
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
Mr. Hyde Xtreme is unusually transparent for a "matrix"-labeled product — despite the branded names, every ingredient and dose is right there on the label, nothing hidden.
Energy is genuinely excellent, powered by a real 378mg caffeine dose from three combined sources, and mood/focus is solid too.
Pumps are the clear weak point — both nitric-oxide ingredients are dosed on the lighter side.
Honest take: A genuinely strong energy formula let down by weak pumps.
