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.

My Favorite caffine supplement

Crush is my go to when It is after coffee or if coffee is not available. This product does not spike you, give jitters, or rapidly fade and crash you out. I enjoy the energy boost without the crash that energy drinks and products give you. I use in all aspects of my life.

Feel more like myself on Crush

Crush gives me a kind of energy that just feels natural. I find myself feeling more motivated and focused, so I inherently WANT to try harder. There’s definitely a physical energy boost too but not in a jittery, forced way. I keep an emergency stash in my car, climbing pack, and running vest because I can’t train without at least one cap!

Best Caffeine Supplement

I’m not one to write reviews, but this product deserves the recognition. It’s been a game changer for me. It boosts my energy, no jitters, no crash, and actually boosts my mood too which I was not expecting. Also no bloat, like I often get from coffee or matcha green tea powders. Great product, as are all of the PhysiVantage products.

Try it

This helped improve the time I was able to keep climbing for each session by quite a bit. I went from spending about 1.5 hours climbing at the gym to 3! With plenty of rest of course, but still. My climbing volume has increased greatly and with that my skills have dramatically increased. I recommend these to all my climbing friends.

NIAHD for old guys fueled by Crush!

Combined age of 122 years, Bill Price and I climbed The Nose of El Capitan in 13 hours and 6 minutes. Half way up we popped some Crush,(and I, some Ibuprofen) and we had a second wind to get the job done. Feeling 10 years younger!
