The health and fitness industry has experienced a meteoric rise over the past two decades, yet its slick exterior conceals a darker side. Using ethnographic data from gyms, interviews, and social media platforms, this book investigates the growing consumption of image and performance enhancing drugs (IPEDs), the motivations behind their use, and their role in masculine body image. Addressing a gap in the literature, Nick Gibbs also interrogates both the offline and digital drug supply chains with important insights for IPED harm reduction practitioners, law makers and policy advisors.
