Speciogynine is a minor indole alkaloid found in the leaves of Mitragyna speciosa.
Speciogynine is a stereoisomer of mitragynine. Because the two are isomers, they share the molecular formula C23H30N2O3 and differ in three-dimensional arrangement.
It occurs as one of the minor alkaloids in the leaf and is separated from mitragynine by chromatographic analysis.
Every batch we ship is third-party lab tested with a certificate of analysis on file.
