Trial Length | 1-6 months |
Number of Subjects | 57 |

Untrained men were put on a periodized strength training program and given either placebo or 300 mg of ashwagandha root extract twice daily for 8 weeks. The ashwagandha group improved their 1RM of bench press by almost 20 kg over placebo and leg extension by almost 5 kg. Muscle size, serum testosterone, and muscle recovery as measured by plasma creatine kinase was also improved versus placebo.
