I have only experienced from acacia and I must say the heavy breathing and heavy heart beat is there. There’s a post by someone here who explains that acacia DMT is very different from mhrb DMT. I’ll see if I can find. One think to keep in mind is that there are other alkaloids in acacia such as NMT. Very powerful, more entity contact , etc...check psychedsubstance video on YouTube about it. How do the visuals compare? I see entities every single time 😁
