Same extract, same specification, a name that finally describes it. Why we have retired the 1:200 name and what the 2.4e stands for.
A new storefront for the same single product we have sold since 2004 — TKA 2.4e™ standardised Tongkat Ali root extract. What is in the bottle, why the batch number and certificate of analysis are published up front, and what else has changed.

1:200, 10%, 2.4% — the numbers on a Tongkat Ali label measure different things. What eurycomanone is, why concentration has a sensible middle ground, and what to ask a seller before you buy.
