We are closing the De Anza location and are moving to Santa Clara. The remaining inventory will be moved and will reopen on October 31. (Due to internet connection issues) The web site inventory will be corrected to show only what we have in stock, and pick ups will be by appointment. 

Thank all of you wonderful customers for the last 33 years, under my ownership and 69 years in total!

Details

Release the hounds with GU’s version of rocket fuel—Roctane Energy Drink. The proven combination of glucose and fructose is the most easily and rapidly absorbed form of carbohydrate. And, a high electrolyte content is just what your legs crave to fire properly, while 35mg of caffeine stokes your central nervous system, increasing the release of free fatty acids into your bloodstream, and further sparing your limited glycogen stores. Plus, taurine and beta-alanine improve muscle endurance throughout the grinding hours of a road race, marathon, or triathlon. Branched-chain amino acids speed recovery and reduce muscle damage, histidine buffers against acidic byproduct, and of course the delicious flavors go down easy.

Nutritional information

Nutritional information may vary per flavor

Caffeien stimulates the central nervous system—the bodie's comunication line from ther brain to the muscles. Through this stimulation, higher power can be attained for longer periods of time. Caffeiene has also been shown to increase the flow of free fatty acids in the bloodstream, possibly sparing your limited glycogen stores by burning fatty acids in glycogen's place.

Grape: 0mg
Tropical Fruit: 35mg
Lemon Lime: 35mg
