Frequently Asked Questions

What ingredients should I look for in a pre-workout supplement?

The most research-backed pre-workout ingredients include caffeine for energy and focus, citrulline malate for blood flow and pumps, beta-alanine for endurance, and creatine for strength. Look for products that list exact dosages rather than proprietary blends. Effective doses are typically 200mg caffeine, 6 to 8 grams citrulline, and 3.2 grams beta-alanine per serving.

How long before a workout should I take pre-workout?

Take pre-workout 20 to 30 minutes before training for optimal results. Caffeine peaks in the bloodstream around 45 to 60 minutes after ingestion, while citrulline and beta-alanine need about 30 minutes to take effect. Taking it too early means the effects may fade mid-workout. If you train in the evening, consider a stimulant-free formula to avoid disrupting sleep.

Can pre-workout supplements cause side effects?

Common side effects include tingling from beta-alanine, which is harmless and temporary, and jitters or anxiety from high caffeine doses. Some people experience digestive discomfort if taken on an empty stomach. Start with half a serving to assess your tolerance. Avoid taking pre-workout within 6 hours of bedtime, as caffeine can significantly disrupt sleep quality.

Is it safe to take pre-workout every day?

Daily use is generally safe, but cycling on and off every 6 to 8 weeks helps prevent caffeine tolerance buildup. Your body adapts to stimulants over time, reducing their effectiveness. Consider using stimulant-free pre-workouts on lighter training days. Taking rest days from pre-workout helps maintain sensitivity so you get the full benefit during intense sessions.

What is the difference between stimulant and stimulant-free pre-workout?

Stimulant pre-workouts contain caffeine and sometimes other energizers for an immediate boost in energy and focus. Stimulant-free versions rely on pump-enhancing ingredients like citrulline and nitric oxide boosters without caffeine. Stim-free options are ideal for evening workouts, caffeine-sensitive individuals, or those who prefer to get their caffeine from coffee separately.
