Welcome to the Nexus!

If I was you I would use a bit of MHRB or dmt extracted from it for your ayahuasca analogue instead of the phalaris arundinacea, unless you isolate the wanted alkaloids. Phalaris can have gramine and other alkaloids of unknown activity and toxicity, so be sure what youre doing and dont just consume a brew made of some untested phalaris please!

What are you gonna use for a MAOI?
