Serving size: 2 scoops (21.7g)
Pre‑Workout powder delivering a high‑dose blend of citrulline, betaine, caffeine and nootropic actives for energy, pump and focus.
+ Strong nitric‑oxide support from 3.5 g L‑citrulline per serve. + Stimulant synergy with 200 mg caffeine plus L‑tyrosine and taurine for alertness. + Added cognitive boost from lion’s mane, NeuroPEA and pine bark extract. + Proprietary blend keeps exact ingredient amounts undisclosed, but label lists each active.
- Proprietary blend limits full dose transparency. - Combined stimulants may increase jitteriness or heart‑rate effects in sensitive users.
All variants share the same core formulation and ingredient list, with only flavour and pack‑size differing; larger packs tend to offer better value. The blend’s mix of vasodilators, stimulants and nootropics sets it apart from typical pre‑workouts that focus solely on energy or pump, though the synergistic caffeine pairings carry a modest overstimulation risk for those sensitive to stimulants.
