10 min : Caffeine enters the bloodstream. The slower absorption curve from the sugar load means a more gradual rise in plasma caffeine — less of a sharp spike versus a 250ml sugar-free format.

30 min : Taurine (2000mg) and B-vitamins now active. The combined adenosine blockade and dopamine modulation from the larger caffeine dose produces a more pronounced stimulant effect than Red Bull at equivalent body weight.

45 min : extended peak. The sugar-modulated absorption curve keeps plasma caffeine near peak for longer than a faster-absorbing format. The insulin response from 54g sugar begins pulling glucose into cells, sustaining the energy sensation.

5–6 hour half-life : affeine halves — but 80mg still active. The high sugar load means a concurrent glycemic crash compounds adenosine rebound, producing a more pronounced energy dip than low-sugar energy drinks.
