Frequently Asked Questions
Can I stack creatine with a pump-focused pre-workout?
Yes. Daily creatine (3–5 g maintenance) complements pump-focused pre-workouts that contain citrulline or Nitrosigine. Take creatine daily for strength gains and consume the pump pre-workout 20–30 minutes before training for best acute blood-flow and focus effects.
Are tingling and itchiness dangerous?
Tingling from beta-alanine or Nitrosigine is usually harmless and temporary, caused by normal sensory responses. If sensations are painful, accompanied by dizziness or chest pain, stop use and consult a medical professional.
Which formula is best if I train in the evening?
Choose a stimulant-free option like LEGION Pulse to avoid sleep disruption, or use low-stimulant servings of formulas with lower caffeine. Always check serving directions and avoid high-caffeine tubs close to bedtime.
