So the OP was talking about IM/SC/IV? The method in ingestion in conversation was inhalation, therefore the dosage in conversation is the dosage for inhalation. I am sorry if you think that vaping/smoking 60-100mg of DMT is the "adequate" amount, if you do some searching on here you will find that is quite to the contrary, no matter if your source is alex shulgin. Promoting that sort of information is just reckless to be honest.
