Theacrine is a potent energy boosting supplement similar in structure and effects to caffeine, but offering some unique advantages. Like caffeine, Theacrine provides boosts to energy, stamina, focus, mood, and motivation. What makes Theacrine unique, however, is that a tolerance to its effects builds at a much slower pace than does a tolerance to the effects of caffeine. Theacrine Depot is a subsidiary of Double Wood Supplements. Our Theacrine is manufactured in New York city and tested for purity right here in the USA.
