Purity and accurate dosage is a function of your vendor. Buying 2C-B pills will be more dangerous, they are notoriously underdosed and should ideally be sent to a lab first, but at the very least spot-checked with a reagent test kit.
Duration is a subjective preference, I feel. LSD is nice, I like it very much, but I can understand than 12 hours uninterrupted is not something everyone can allocate in their schedule.
I stick to low dosages, partly to avoid nausea and partly because I like to be somewhat cautious with this delicate biological machinery I don't understand.
For me it's also something I can take a small dose of occasionally when I have a big night out, if I'd like to sleep early, or if I'd like more stimulation and less headspace.
LSD I use for long introspective trips, physically by myself so that I can tune in and out of online social interactions depending on how I feel.
I feel like 2C-B is a nice option to have for different settings. Since I don't very much experience the downsides it's worth it for me, but I can definitely acknowledge the downsides =)
Zofran works for my friend, zofran. Whether it’s specific serotonin blocking effects that fixes the nausea has +/- psych experience is unknown.
(Supposedly it can contribute to serotonin syndrome, but I don’t understand the mechanism. Seems theoretical, but don’t say I didn’t warn you).
LSD is a different ballgame from the 2C family IMO, its difficult to compare. From my experience (again this is quite subjective) the visuals from LSD weren't as "thick" and deeply colorful. They had a sort of whispyness to them and (usually) a much deeper headspace
This is what I remember about 2CB. It looked like the Matrix effect to me but in translucent rainbow colors.
