Best pump formula I've ever used. Stim-free so I can stack it with anything. The vascularity is insane — highly recommend.

Performance FAQs
Got questions? We've got answers — plus free consultations at both Fort Wayne locations.
What's the difference between a pump formula and a pre-workout?
+
Pre-workouts typically contain stimulants (caffeine) plus performance ingredients. Pump formulas are stimulant-free and focus entirely on vasodilation — increasing blood flow to muscles for better pumps, endurance, and nutrient delivery. They can be taken alone or stacked with a caffeinated pre-workout.
Can I take a stim-free pump formula at night?
+
Yes — that's one of the biggest advantages of stim-free formulas. No caffeine means no sleep disruption, making them ideal for evening or late-night training sessions.
How do I know if a performance supplement is clinically dosed?
+
Check the supplement facts panel. If you see exact milligram amounts for every ingredient (not hidden in a "proprietary blend"), it's transparent. Then cross-reference each ingredient against published research doses. Our staff can walk you through this — we check every product we carry.
Can I stack a pump formula with creatine?
+
Absolutely. Creatine and a pump formula is one of the most effective performance stacks available — creatine increases strength and power output while the pump formula maximizes blood flow and muscle fullness. Mix creatine directly into your pump drink for convenience.
How long does the pump effect last?
+
Most pump ingredients (like L-Citrulline and Agmatine) peak in the bloodstream within 60-90 minutes and provide effects lasting 2-3 hours. Taking your supplement 20-30 minutes before training optimizes the overlap with your actual workout.
Are performance supplements safe for women?
+
Yes. Performance and pump supplements are safe and effective for women. Many female athletes use them to improve vascularity, endurance, and recovery. There are no hormone-affecting ingredients in standard pump formulas. Our staff can recommend the best options for your specific goals.
