The Science:
CRUSH is a novel ergogenic and nootropic supplement comprised of a synergistic blend of L-theanine and caffeine, augmented with L-tyrosine and L-taurine. Numerous studies have shown that L-theanine and caffeine can improve attention span, enhance the ability to process visual information, and increase accuracy when switching from one task to another. By boosting levels of GABA (a neurotransmitter), L-theanine also enhances Alpha brain waves associated with a state of “wakeful relaxation", thus taking off the "edge" (anxiety and jitters) off the stimulating effects of caffeine.

One often unrecognized (and undesirable) side effect of caffeine is vasoconstriction, which can hinder muscle capillary blood flow. To combat this unwanted effect, CRUSH contains L-taurinea proven vasodilator that also has been shown to reduce muscle cramps.

Last but not least, CRUSH includes a moderate dose of L-tyrosine, an amino acid shown to improve mental performance in stressful situations. Compared to placebo, tyrosine was found to improve cognitive flexibility and working memory during mentally demanding tasks, as well as help sleep-deprived individuals stay alert longer.

Caution: Persons with thyroid disease, who are pregnant or nursing, or who are taking MAO inhibitors or other medications should seek the advice of a physician before consuming this supplement.

Perfect Balance

I’m really digging the Crush supplement. I can’t stand being jittery or over caffeinated. Find it to almost backfire when it comes to performance. Crush is a wonderful blend of alertness and calm that allows for maximum focus without the anxiety.

A healthy tweak

Stuff works and gets you going that’s for sure !!! Especially after work helps a lot

Great pre workout

Awesome stuff, gives me energy without jitters or a crash.

Love it!

Love the pre-workout! I've tried to use other products for pre-workout, but they make me itch and jittery. The crush doesn't make me feel negative side effects and just gives me that extra edge that I need.


Good supplement but messed with my sleeping even way after 6 hours after taking.. took half a dose in the morning and the following night I got no sleep what so ever. My body was tense and my mind felt really active all night. And I'm use to having 300 mg + of caffeine a day but I guess the caffeine mixed with the nootropics is what was the problem.. maybe just me
