This means 200 grams of Tongkat Ali roots is used to produce 1 gram of extract. Also, only aged roots of 10 years are used in the production of SD-200 because according to a research done my MIT, only old roots contain the “secondary bioactive metabolites”. These roots are wild crafted from the lush tropical rainforest of Sumatra, Indonesia where it is untouched by pesticide and industrial pollution.
