What is in TestoJack 300?
Each row as the label prints it, per serving of 1 veg capsule. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

|---|---|---|---|
| Tongkat Alias Eurycoma longifolia jack extract | 300 mg | Higher than 77% of 496 products listing eurycoma longifolia (median 100 mg). |
