Outlining a Typology of Steroid Suppliers Located on a Popular International Fitness and Bodybuilding Forum

With understanding access and supply of drugs important to harm reduction, this article explores IPED supply on a ‘surface web’ fitness forum, outlining a typology of suppliers located in this space, through a digital ethnography drawing data from over 28,800 unique forum posts.
