Is DMHA present in Kigelia africana?
DMHA
Speaking of doping, the popularity of DMHA leads to doping cases. Athletes who use DMHA test positive for heptaminol, another stimulant. In the body, DMHA converts into heptaminol.
Natural?
In 2014, Australian researchers did indeed find DMHA in Kigelia africana. [Pharmacog. Comm. 2014, 4, 10-32.] But if you read their publication, you can see that the amount of DMHA in Kigelia africana is very, very small. So small that it is almost inconceivable that the DMHA in supplements comes from this plant.

The researchers did not find DMHA in any plant extract.
The outcome of the analysis of the supplements was less clear. DMHA was in 4 of the 13 supplements, but not in the other 9. In the 4 products in which the Americans did find DMHA, the concentration varied considerably.
When the Americans analyzed the DMHA in the supplements, they discovered that it was of industrial origin. The DMHA in the supplements was a mixture of enantiomers. Natural DMHA is a single substance, not a mixture.
In addition, the Americans found in the supplements substances that arise during the chemical synthesis of DMAA, but which the manufacturer was unable or unwilling to purify.
