From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
Δ5-Androstenediol (abbreviated as Δ5-diol), commonly referred to simply as androstenediol, and also known as androst-5-ene-3β,17β-diol, is an endogenous androgen and estrogen steroid hormone and intermediate in the biosynthesis of testosterone from dehydroepiandrosterone (DHEA).
One study found it to have coxsackie b4 antiviral activity 100 times more potent than DHEA.[1]
