drug nerd here. I've tried close to 100 chemicals recreationally including 20 psychedelics and several dissociatives including DXM, MXE, Ketamine and Diphenidine. Never managed to get MXP or 3-meo-pcp unforunately. Diphenidine is the weirdest drug I've ever done. It's like DXM mixed with crack. I'm a drug nerd whose spent dozens of hours studying pharamcology and can tell you pretty much anything unique about a drugs pharmacological profile.

DXM is unique among dissociatives for its serotonergic effects. It acts as an SRI IIRC.

Waltussin is the best brand to get but really anything that just includes DXM as an active ingredient is fine. As another anon pointed out there are two types but its not HBr and HCL but HBr and polyistrex. I don't believe you can get DXM HCL otc but you could potentially extract it into that form. Polyistrex is supposed to metabolize half as fast and so it lasts twice as long but its not worth it so if you find some in that form don't take it.

Walgreens Waltussin brand comes in gel-caps that are by far the easiest form to take. Start at 125mg because you could be sensitive to it based on your enzymes. If you're deficient in, I believe, CYP34A enzymes then you will need MUCH less DXM because it won't be metabolized as much. If you're an alcoholic I'm pretty sure you will be deficient in this enzyme.

People used to talk about MXE just like you guys are talking about DXM but only moreso because you can't buy that shit OTC you actually had to find an RC vendor.
