Do yourself a favor and don't ingest the seeds, whole or ground up, in a capsule.  That makes the timing of the onset of MAO inhibition unpredictable, which in turn makes the amount of dmt effectively entering the system also unpredictable. 

Make a tea instead, or even better yet, make a crude extract from the tea with common salt.  An extract can be measured.  Ingest the harmala and dmt together, whether in the form of capsules or in the form of a solution (a solution is preferred.) 

Prepare multiple doses of 25 mg dmt and 75 mg harmala combined and ingest one dose every hour, until you feel that you have liftoff.
