In Testo Junkie, Preciado briefly introduces the figure of the ‘techno-Barbie’. Contrasted with his own Testogel-fuelled pornographic experiments, the possibilities of oestrogen or progesterone seem somewhat uncharitably foreclosed upon. Though Preciado draws our attention to the gendered politics of chemical enhancement and hormonal justice, it begs the question: where do we draw the line between experimentation and chemical domination? We engage with the figure of the techno-Barbie to explore our own experiments with hormones and gendered agency in the boundaries of (...) advanced biocapitalism. Drawing on a range of allied texts, we explore the ambivalences of our own hormonal experimentation. What kinds of hormonal experiments are allowed to be cast as such?
