Very few if anybody will know how THH compares because most people were getting fake THH from FV. Harmaline is just fine for pharma, and so is harmine. I like them both, try both at different times and see for yourself.
I agree with oneistheall, start with low dmt dosage, I would say at most 50mg for first time, and then see how that goes for you. For some people that isnt much at all, for others its already quite significant dosage.
As for dosages, its linked in the FAQ, which takes you to this thread:
https://www.dmt-nexus.me...p;m=11514&#post11514I would say for first time maybe try dissolving both together in some acidic juice (like orange juice) and drinking it up.
Have your dmt pipe ready in case the trip isnt so strong and after 2 hours you dont feel much. I also suggest some neutral juice like watermellon, to drink during/after the trip, to refresh and get some nutrients in your body without being heavy on the stomach
Good luck and let us know how it went!
