Is tongkat ali a good supplement to boost testosterone?

Supplements: The body generally does not need supplements to produce hormones. The regulatory system of hormone regulation generally does not react well to artificial manipulation and often causes more harm than good if there is not a hormone deficiency. Hormone deficiencies are generally treated with synthetic versions of the hormones, not pro-hormones or supplements.

Yes: There are some studies that support the use of tongkat ali to raise testosterone. This study - http://www.Ncbi.Nlm.Nih.Gov/pubmed/23754792 - published in phytotherapy research, 2013 by henkel rr, et al, found that "treatment resulted in significant increases in total and free testosterone concentrations and muscular force in men and women." feel free to research more at www.Pubmed.Gov.
