G-5, also known as 3,4-norbornyl-2,5-dimethoxyamphetamine, is a psychedelic drug of the phenethylamine, amphetamine, and DOx families.[1][2][3] It is one of several homologues of Ganesha (G).[1][2][3]

Use and effects

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists G-5's dose as 14 to 20 mg orally and its duration as 16 to 30 hours.[1][2][3] It is said to have a very slow onset.[1] The effects of G-5 were reported to include an unexpected absence of visual and related sensory activity, excellent mental activity, "absence of the bells and whistles that are expected with a psychedelic in full bloom", mental integration, and little or no body load.[1] According to Shulgin, it was somehow lacking in characteristics that would have made it fully favorable, perhaps the lack of perceptual effects, which resulted in there being little drive to further explore it.[1]
