    Summary PsychonautWiki

    2,5-Dimethoxyphenethylamine (also known as 2C-H) is a lesser-known psychoactive substance of the phenethylamine class. 2C-H belongs to the 2C-x family of substituted phenethylamines. However, it does not have any significant psychedelic properties and is primarily used as a precursor in the synthesis of other phenethylamines such as 2C-B, 2C-I, and 2C-N.

    0:00 Now, I am just taking 15mg out of my container in which I synthesized the 2C-H and put it on my fingertip; then let it dissolve in my mouth. 0:01 I feel excited but I know that there is nothing to be excited about.

    I had posted in another forum I received DMPEA, it was a large jug of foul smelling light brown liquid that smelled like ammonia and old urine as I had mistakenly obtained the freebase instead of HCl. I had known all along that it would be active despite everyone else's dismissings.
