Achieve optimal mental performance with CILTEP®, Smart Caffeine™ and BioCreatine™.  When taken together this carefully designed stack creates the ideal mental state for long lasting concentration and enhanced cognitive ability. The combined benefits include:

  • Increased motivation and mental endurance

  • Focused energy without jitters or anxiety

  • Enhanced cognition and lean muscle gains

CILTEP®
CILTEP® is the only natural way to optimize the intracellular messenger systems in the brain for improving and maintaining peak mental performance. It's specifically formulated to increase motivation, concentration, and memory.

Recommendation: Take 1 serving immediately upon waking on an empty stomach.
Smart Caffeine™
SmartCaffeine™ is a simple and effective way to boost drive and focus. It significantly improves alertness and cognition without the nervousness and jitters of regular caffeine sources.

Recommendation: take 1 serving whenever focused energy is desired (we suggest mid-morning and/or mid-afternoon).
BioCreatine™
BioCreatine™ provides the cellular ATP energy needed to support the benefits of CILTEP and SmartCaffeine for accelerated learning and extended concentration.

Recommendation: take 1-2 servings per day (we suggest mid-morning and/or mid-afternoon, or after exercise).

It’s your right to know what exactly you’re putting into your body.

Most companies use “proprietary blends” so they don’t have to tell you the amount of each ingredient in their formulas. It’s a shady and sometimes dangerous practice. At Natural Stacks we proudly publish our innovative formulas in an open source format.
