Powerfully put! One can't distinguish the other before trying either of the two. Each in its equivalence is powerful. When you think tryptamine you think mushroom and when you think Phenethylamine your thoughts brew of LSD. But let that idea fade because its not. If you want to hail phenethylamines think of that natural version of Lysergic which is mescaline.You overestimate language... can you describe the diffirence between the taste of coffee and tea?
