It varies. SWIM gets decent effects with just 5 mg sublingually. Some people prefer 10 mg or more. It's a good idea to start with no more than 5 mg to test your tolerance to it. A high dose of 5-MeO-DMT can really freak some people out. It does some very weird psychedelic things to the mind. It’s got all the mental “mind fuck” of acid and then some. The visuals are usually lacking and unimpressive.
SWIM likes it a lot though. It’s very euphoric if the dose is not too high. For SWIM it’s like a very short acid trip, but not as visual.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
