Tongkat Ali Root Extract does not “boost” your testosterone.

However, it may “free” up more of your testosterone to be used.

We don’t use the majority of our total testosterone because it’s bound to a protein known as Sex Hormone Binding Globulin (SHBG).

Tongkat Ali appears to increase your free, or useable testosterone, by essentially lowering your SHBG.

If you’re going to try a supplement such as this, I still recommend getting labs drawn before starting and after about 8 weeks. And make sure it’s a quality sourced and quality dosed product.
