DOI is interesting because it's one of the most selective 5-HT2A agonists. Unlike most psychedelics, it doesn't really stimulate the 5-HT2B receptor that is linked to heart problems. And it also seems to have powerful anti-inflammatory properties.
I ended up ordering DOC from rarechems, who recently started shopping to the US. They reported they shipped it 5 days after the order and I received it 11 days later.
