MDMA mixed with DPT was disappointing, personally speaking. However, for me mixing DPT with aMT (a chemical that is pharmacologically pretty similar to MDMA) was superior to MDMA + LSD, so it's totally unpredictable. I found 4-ho-MPT pretty subtle and would never even consider mixing it with MDMA. In any case, there's no pharmacological reason to prefer one over the other that I know. They're both equally mysterious combinations as far as empirical data is concerned. Go with whichever one you feel will mix best, because it's entirely a matter of your subjective history with these compounds. Our opinions are pretty meaningless, especially with regard to something with such a short history of use as 4-ho-MPT.
