Theacrine
A caffeine-like compound that provides sustained energy without tolerance buildup.
Also known as: TeaCrine • 1,3,7,9-Tetramethyluric Acid
Overview
Theacrine is a purine alkaloid found naturally in kucha tea (Camellia assamica var. kucha) and certain coffee species. It is structurally similar to caffeine but with key differences: it does not appear to build tolerance with repeated use, has a longer duration of action, and provides smoother energy without the jitters commonly associated with caffeine.
