I have been making a few different blends of enhanced leaf with plain caapi 1:1 with dmt freebase and perhaps a pinch of other herbs with some good effects.
I wish to add a harmala to the mix but I am unsure of the best way to achive this. I have found a online source (uk based) that does 25x syrun rue extract. Would this be any good to add at the preparation stage? And if so at what level eg 1 gram freebase 1g caapi leaf/herb to say 1g 25x syrun rue extract.

Any help would be appreciated.

I think the best way is to avoid buying extracts and do it yourself, just get some rue seeds and extract them, its fun and much more rewarding than buying an unknown substance. Its also much cheaper.

Once you extract your rue its trial and error and personal choice for what ratio is going to work for you.

Thanks for the advice. I will look up a few teks and try small batches to see how it goes.

Any further advice would be much appreciated.
