And of course, we also check our tongkat ali roots for heavy metal contamination.

The result (certified from the most prestigious university in Indonesia, the Universitas Indonesia in Jakarta:

Lead < 0.01 ppm (less than 1000 times less than what the EU would allow)
Cadmium < 0.01 ppm (less than 100 times less than what the EU would allow)
Mercury < 0.001 ppm (less than 1000 times less than what the EU would allow)
Arsenic <0.001 ppm (less than 3000 times less than what the EU would allow)

The above table only states, that our values were in most cases less than 1000 times what would have been allowed. But they may even be better than that.

The reason is: even the most sophisticated equipment at the most sophisticated lab was not able to detect ANY TRACE of the contaminants.
