2C-G
Aliases: 2cg
Summary
2C-G is an extremely rare and long-acting psychedelic phenethylamine first synthesized by Alexander Shulgin. It is notable for its exceptionally long duration of 18-30 hours and relatively mild visual effects compared to other 2C compounds. Shulgin described it as an 'insight-enhancer' with effects similar to Ganesha.
Perspectives
“I am completely functional, with writing and answering the telephone, but the coffee really tastes most strange. While the mental effects (to a ++ only) were dispersing, the body still had quite a bit of memory of the day. Sleep was fine, and desirable, in the early evening.”
