  • Send your project!
  • Top your boulder!

50 servings per bottle (100 vegetarian capsules) 

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.

Focus Up!!

Just another gem of a product offered by PhysiVantage! I wash these down with an Endure X and Supercharged Collagen cocktail before heading to the crag, gym, mountain or trail and I really can't speak highly enough about the effectiveness of all 3. No jitters, no skin crawling, no anxiety, no stomach weirdness! Just clean support and enhancement for the body and mind. Amazing products all around!


I have used a fair amount of pre-workout products before hitting the gym to lift. They do not translate well into the climbing world because I feel they focus on getting you pumped to make muscle gains while lifting. This product gives you a boost of clean, non-jittery energy before your training session or your project, without the pre-pump and itch a "normal" pre-workout will do.


This supplement is fantastic. Highly recommended

2 Thumbs up!

I use these for anything from working 12's to long days at the crag, always useful!

Great Product That Has Improved My Energy Level and Concentration

When I purchased my first bottle of Crush I was working 12 hour days and then going to the climbing gym for 2 1/2 hour sessions. I was constantly taking a Five-Hour Energy Drinks and it would make me jittery and upset my stomach. As soon as I started taking Crush I immediately felt better with no jittery feeling, no effect on my stomach, and a tremendous amount of energy. I love this product and have already received my second bottle and I plan to keep using it.
