Pre-Workout FAQs

Got questions? We've got answers — plus free consultations at both Fort Wayne locations.

How much caffeine is in this pre-workout? +

Caffeine content varies by product — check the supplement facts panel for the exact amount. Most of our pre-workouts range from 150mg to 350mg per serving. If you're caffeine-sensitive, we also carry stim-free options.

When should I take my pre-workout? +

Take 20-30 minutes before your workout for optimal absorption and performance. Avoid taking within 6 hours of bedtime to prevent sleep disruption. For evening athletes, a stim-free pump formula is a great option.

Can I stack pre-workout with creatine? +

Absolutely — pre-workout and creatine is one of the most popular and effective stacks in the industry. Just check if your pre-workout already contains creatine so you don't accidentally double your dose. Our staff can help you build the perfect stack.

Why do I feel tingling or itching after taking pre-workout? +

That's beta-alanine doing its job! The tingling sensation (paresthesia) is harmless and a sign the beta-alanine is working to buffer lactic acid in your muscles. It typically fades after a few weeks of consistent use.

Is this pre-workout safe to take every day? +

Most pre-workouts are safe for daily use, but we recommend cycling — 5 days on, 2 days off — to maintain stimulant sensitivity. Taking breaks also helps prevent tolerance buildup. Our staff can advise on the right cycling protocol for your specific product.

Do you carry stim-free pre-workout options? +

Yes! We carry several stimulant-free pump formulas that deliver incredible vascularity and endurance without any caffeine. Great for evening training or stacking on top of your regular pre-workout. Ask our staff for recommendations.
