Today’s fast-paced world leaves many of us struggling with extreme emotional highs and lows caused by chemical imbalances in our brains, brought on by the pressures of modern life and constant digital connectivity.

In The DOSE Effect, neuroscientist TJ Power shares how you can reset and balance your brain chemistry with simple, everyday habits to lead a happier, healthier, and more productive life.

Unlock your brain’s four key chemicals and discover the powers of:

DOPAMINE to get motivated and stay driven

OXYTOCIN to build deeper connections with others

SEROTONIN to boost your energy and mood

ENDORPHINS to destress and find calm

TJ’s practical approach and straightforward solutions will guide you on an exciting, action-based journey to optimise your brain chemistry and transform your mental health so you can feel happier and healthier in your everyday life.

If you're a growth-oriented, forward-looking reader of guides like Atomic Habits, The Subtle Art of Not Giving a F*uck and Why Has Nobody Told Me This Before?, this is the book you need to get your hands on next so you can start changing your life today.
