Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Ketosterones, primarily derived from the plant Eurycoma longifolia (also known as Tongkat Ali), have a long history of use in traditional Southeast Asian medicine. Traditional practitioners have used extracts containing ketosterones to enhance male vitality, libido, and to some extent, physical performance and muscle strength. The rationale behind its application in body building is based on traditional beliefs that these compounds can increase testosterone levels or mimic its effects, thereby potentially supporting muscle growth and recovery.
However, scientific studies evaluating the direct effects of ketosterones on muscle mass, strength, or athletic performance are limited and of varying quality. Most research focuses on the broader extract rather than isolated ketosterones, and results are often inconsistent or preliminary. Some small studies suggest a possible benefit for testosterone production or reduction in exercise-induced stress, but these findings are not robust or universally replicated. Meta-analyses and systematic reviews typically conclude that evidence remains insufficient to recommend ketosterones or Tongkat Ali extracts for muscle building purposes.
In summary, the use of ketosterones for body building is primarily rooted in traditional practices rather than strong scientific validation. While there is some emerging interest and early evidence, current support for their efficacy in this context is weak and warrants further investigation.
