Official title
Exploring the Power of Theacrine: Assessing the Impact of High Theacrine Doses on Hemodynamic Measures, Cognitive Measures, and Physiological Stress
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This project measured physiological and cognitive variables to determine the effectiveness of Theacrine (TCR) as a stimulant at doses greater than those previously tested. The study will be the first TCR study to use doses relative to body weight and will investigate impacts on regular caffeine consumers. A secondary aim of the study is to determine the impact of acute TCR supplementation on salivary cortisol and sAA, two physiological measures of stress and sympathetic nervous system activation. The findings of the study will provide new insight into the effects of higher TCR dosages, contributing to the analysis of TCR as a caffeine alternative for individuals with hypertension, tachycardia, or healthy caffeine consumers wanting to avoid a stimulant with adverse or habitual effects
