Increases testosterone and sexual potency!


TESTOJACK 100 by Now Foods contains a powerful standardized extract of Eurycoma longifolia, commonly known as Tongkat Ali or Jack Long. Clinical and non-clinical studies have shown that extract of Tongkat Ali (LJ100®) supports healthy reproductive health in men by regulating/increasing levels of endogenous testosterone.

Tongkat Ali stimulates testosterone by two different mechanisms:

  • One mechanism works by releasing testosterone from binding globuline, a protein that transports testosterone in the blood and prevents it from penetrating into the muscle cells, where it can stimulate growth.
  • The other mechanism is by stimulating Leydig’s cells which are found in the testicles to directly increase the production of testosterone.

Now Foods has complemented the TESTOJACK formula by adding Tribulus Terrestris and ZMA. Two well-known and effective ingredients used to stimulate the endogenous production of testosterone.


  • Formula precursor to testosterone levels in men.
  • Increases virility.
  • Includes LJ100® Tongkat Ali.
  • Vegetarian formula
