LJ100® Clinically Proven Benefits

Tongkat Ali or Eurycoma longifolia Jack (ELJ), which contains quassinoids such as eurycomalacton, eurycomanon, and eurycomanol, has been reported to have aphrodisiac properties and to increase testosterone levels in men. But unknown to many, Tongkat ali has several other health benefits.
