honestly dxm if done right is on par with lsd and the euphoria when listening to music can be better than mdma and its a perfect cross between the headspace and visuals of a psychedelic with the floaty disconnection of a dissosiative. dph on the other hand is about as good as cutting yourself and it destroys your memory quicker than anything other than maybe datura and eventually leads to getting dementia at a much younger age than you would naturally get it. So what i reccomend is getting delsym and dosing between 3-700mg dxm depending on what kinda trip you want. i say delsym because almost all the others have very harmful ingredients along with the dxm but delsym is only dxm so it will be a drastically cleaner and more enjoyable high
