Ketosterones, particularly those derived from the plant Eurycoma longifolia (commonly known as Tongkat Ali), have been traditionally used in Southeast Asian herbal medicine as a tonic and to enhance physical performance and stamina. The purported use as an athletic or exercise aid is primarily rooted in these traditional practices. In traditional systems, extracts containing ketosterones were believed to improve endurance, energy levels, and muscle strength, although the specific compounds responsible were often not well defined.

Scientific evidence for the efficacy of ketosterones as exercise or athletic aids is limited. A few preliminary studies and animal experiments suggest that extracts containing ketosterones might influence testosterone levels or support physical performance, but these are often small, not well-controlled, or do not isolate ketosterones as the active component. There is a lack of large, high-quality randomized controlled trials in humans that directly support the use of ketosterones for improving athletic performance or exercise outcomes. Most claims remain unsubstantiated by rigorous scientific research, and authoritative reviews generally conclude that more evidence is needed before recommending ketosterones for this purpose.

In summary, the use of ketosterones as athletic or exercise aids is primarily supported by traditional use, with limited scientific backing and insufficient high-quality evidence to confirm efficacy.
