I know quite some academic sources cite EA as the rex solvent. But from all my experience it is bad here :?: Not really a safe way to get crystals. One time it turned brown afterwards, pictures attached at the TEK.

Jonathan Ott used it in his Pharmanopo paper, but actually it sounds more like it did not work, so he placed it aside and forgot about it, just to realize after days randomly crystals formed  (placed in Freezer 1 night, then in Fridge for several days :? ).

Xylene will 100 % form crystals upon slow cooling, they can be very hard and brown-translucent.

Still actually, when anyways going for an E-Juice, I would even prefer the oil, as this will dissolve even better in your PG. Once crystallized it might be much harder ... and even pure Bufotenin being dark brown means there is no downside of stuffing dark stuff into your E-Juice, will still be a good-quality product.

Sounds reasonable, then you could directly extract with warm PG on your conserted matter, I guess the salts would never dissolve anyways? And then add the residual VG.

Cool news on the vaping efficiency. Yes it's stronger than DMT by maybe 1,5-2x, but still not as strong as 5-MeO. E-Juice-Vaping could be indeed stronger, as with pure Freebase-Oil-Vaping you will destroy 20-50 % Bufo while heating.

The only good thing about concentrate-vaped Freebase Bufo is the aroma of roasted nuts, but only when you do 1-2 mg and remotely smell the vapor
