DMT is dimethyltryptamine, and there is only one dimethyltryptamine. In other words, DMT is DMT. It exists many related substances such as 5-MeO-DMT, bufotenin and psilocin, but none of them is DMT. For Ayahuasca, you should only use DMT, not the other substances. You also need harmala-alkaloids, for example from Banisteriopsis caapi or Peganum harmala.
Where and how did you obtained this substance you are unsure of what is? You should really extract your own, so you are sure of what you are ingesting.
