testadon

Testadon is a fictional chemical compound frequently referenced in science fiction and world-building to illustrate a hypothetical performance-enhancing drug.

The name is a portmanteau of 'test' and a common chemical-suffix used for synthetic steroids, chosen to suggest a steroid-like, man-made analogue.

In the fiction, Testadon is described as a small, lipophilic molecule that can be taken orally. It is said to boost muscle protein synthesis and endurance, sometimes via an unspecified receptor or signaling mechanism. Side effects depicted in stories include hormonal disruption, liver stress, and cardiovascular concerns.

As a narrative device, Testadon is used to examine issues surrounding doping, medical risk, sport ethics, and regulatory policy, without referring to a real-world substance.
