Research suggests that theacrine does not meaningfully improve exercise performance or subjective readiness in resistance-trained individuals, based on a single randomized, double-blind crossover trial. Studies indicate that when compared to caffeine and placebo, theacrine produced no significant improvements in objective measures such as strength, power, or muscular endurance, nor did it enhance self-reported energy, focus, or motivation to exercise. The available evidence is limited to one small study of twelve participants, which constrains how broadly these findings can be applied, and it remains unclear whether different doses, populations, or exercise modalities might yield different results. Overall, the current research does not support theacrine as an effective standalone supplement for exercise performance enhancement.
