Five questions to ask any Tongkat Ali supplier

Eurycomanone is Tongkat Ali's principal active compound. The clinically researched dose for testosterone is 1.6mg a day, and extracts with similar labels can deliver very different amounts.

QuestionPhystaTypical extract
How much eurycomanone does it contain?0.8 to 1.5%, every batchOften unstated
Are its other active markers controlled?Yes, three moreRarely
Has it been studied in humans?Yes, in 28 human studiesNo
Is the identity of the root verified?Yes, by HPTLC testingOften not
Can it be traced to its source?Yes, fully tracedRarely fully
Clinically researched dose

200mg of Physta a day delivers at least 1.6mg of eurycomanone, the clinically researched dose for testosterone.

Eurycomanone content, % of extract
Physta eurycomanone range Physta is standardised to between 0.8 and 1.5 percent eurycomanone. Extracts below 0.8 percent are under-standardised. Levels above 1.5 percent have not been clinically researched. Physta range Under-standardised Not clinically researched 0%0.5%1%2% 0.8%1.5%
  • Under 0.8%: under-standardised
  • 0.8 to 1.5%: Physta range
  • Over 1.5%: not clinically researched

Percentage × daily dose = milligrams of eurycomanone. At 200mg, 0.8% delivers 1.6mg and 1.5% delivers 3mg. A ratio such as 200:1 refers to the quantity of root used, not the strength of the extract. What extract ratios mean

Sourcing and supply

Sustainably sourced. Extracted to standard.

Physta begins with Tongkat Ali root from Malaysia's biodiverse rainforests. Every batch is extracted, standardised and tested to the same specification.

  1. Sourced

    Harvested by Orang Asli communities, who are paid a premium. Four seedlings are planted for every tree harvested.

  2. Authenticated

    Each incoming batch of root is HPTLC tested to confirm species and plant part.

  3. Extracted

    By a water extraction process co‑developed with MIT.

  4. Standardised

    To MS 2409:2011, the Malaysian Standard Physta helped develop.

  5. Tested and released

    Every batch is tested for heavy metals and microbes before release.
