### Ingredient Breakdown

STIM-CRAZY CAFFEINE COMPLEX†

Consisting of Caffeine Anhydrous, Dicaffeine Malate, Theobromine, Green Tea, Yerba Mate Extract, Guarana Extract, Green Coffee Bean Extract, and Gotu Kola Extract. This is a precise combination of eight types of caffeine, sourced specifically to create a smooth, extended energy curve while effectively eliminating caffeine jitters and the “caffeine crash” that accompanies most highly caffeinated products.

Prepare yourself for what’s next, blasting yourself into a gym session fueled by a blend of caffeine from 8 sources:

COCOABUTEROL Cocoa Alkaloid Extract (_Theobroma caco L.)_

Cocoabuterol® is a new dietary weight loss supplement to activate thermogenic fat burning within the body while boosting your energy and mood. The natural alkaloids in Cocoabuterol® can significantly increase cAMP via beta-adrenoceptors, thereby activating thermogenic fat-burning and muscle-building functions. This translates to fat burning PLUS support for the building of lean muscle tissue without the side effects.

Compared with caffeine, Cocoabuterol® doesn’t have the edginess often associated with caffeine, while it lasts longer and similarly balances the onramp and offramp of caffeine into your body, enhancing caffeine’s most desirable qualities. Because Cocoabuterol® acts to smooth out the caffeine curve, you’re unlikely to experience the shakes and jitteriness associated with excessive caffeine consumption.

CAFFEINE ANHYDROUS

Commonly used as a fast-acting energy source, Caffeine Anhydrous has appeared in many of the best pre-workouts and energy-based products. This ingredient will assist with mental alertness by stimulating the central nervous system, enhancing your energy output in a short time.

DI-CAFFEINE MALATE

What makes Di-Caffeine Malate such an effective ingredient for prolonged energy output centers on the time-release properties. Like caffeine, Di-Caffeine Malate helps improve energy levels and mental focus. Best of all, Di-Caffeine Malate helps endurance and stamina, supplying you with energy when you need it most during hardcore training.

THEOBROMINE

Theobromine is similar in structure to caffeine and falls into the same class of methylxanthine compounds. Although theobromine is similar in structure to caffeine, it’s only about 1/10th the strength of caffeine.

Theobromine is somewhat unique in that, compared to most stimulants, it's actually been shown to _decrease_ blood pressure. It has mild vasodilatory properties, similar to those of the amino acid Arginine, and is believed to increase blood flow.

OTHER SOURCES OF CAFFEINE

Caffeine sourced from Green Tea leaves, Yerba Mate Extract, Guarana Seed Extract (_Paullinia cupana_), African Snakeroot (_Rauwolfia vomitoria_)(leaves), Green Coffee Bean Extract (_Seed_), and Gotu Kola Extract (_Centella asiatica_).
