It's really hard to know how pure an extract is until it starts loosing color. I would recommend trying it on it's own without DMT to know what the right dose is for MAO inhibition. At about an hour to 1.5 hours, you should notice a definite intoxication effect that lasts at least another hour, but not anything intense. When you find this dose, repeat and follow directly or no more than 20 minutes later by 30-40mg DMT.
