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.

200mg of Physta a day delivers at least 1.6mg of eurycomanone, the clinically researched dose for testosterone.
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
Physta begins with Tongkat Ali root from Malaysia's biodiverse rainforests. Every batch is extracted, standardised and tested to the same specification.
Harvested by Orang Asli communities.
Each incoming batch of root is HPTLC tested to confirm species and plant part.
By a water extraction process co‑developed with MIT.
To MS 2409:2011, the Malaysian Standard Physta helped develop.
Every batch is tested for heavy metals and microbes before release.
