    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.
