how legitimate is a 22 percent Eurycomanones in a tongkat ali supplement?

I have been a loyal Nootropics Depot customer (especially their Tongkat Ali) for close to a decade and I know how most suppliers of tongkat ali supplements have negligible eurycomanone content. Refer to: https://nootropicsdepot.com/articles/what-you-need-to-know-about-tongkat-ali-extracts/
Therefore, when a supplement company from my side of the world (Southeast Asia where Tongkat Ali is produced) is claiming to have a standardised 22 percent eurycomanone product at 20 USD per bottle, I am a little skeptical. I am just wondering whether do you think the logistics/price point checks out? Is this a legitimate brand? Does anyone have any thoughts on this?

The CoA shown on the product page appears to cover only microbial contamination and heavy metal levels. Request the CoA that includes eurycomanone content. If that assay is performed in-house, ask for details on the analytical method used and how it was validated.
I would say a claimed 22% eurycomanone is doubtful. Even the LJ100 extract from Malaysia, one of the origin countries of tongkat ali, is reported by MYASD to contain less than 2% eurycomanone.

LJ100/Physta contains 0.5% to 0.8% eurycomanone in most batches we test.
