2C-G-5, also known as 3,4-norbornyl-2,5-dimethoxyphenethylamine, is a psychedelic drug of the phenethylamine and 2C families. It is one of several homologues of 2C-G (3,4-dimethyl-2,5-dimethoxyphenethylamine). The drug is taken orally. 2C-G-5 was encountered online as a novel designer drug in 2025.

Use and effects

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 2C-G-5's dose as 10 to 16mg orally and its duration as 32 to 48hours. The drug's onset is 1 to 2hours and its time to peak is 2.5 to 3hours. 2C-G-5 is reported to produce psychedelic effects including visuals, clear and cosmic thinking, and 2C-B-like enhanced eroticism, among others. It is among the most potent of the 2C psychedelics. However, its duration is described as too long, interfering with sleep and resulting in subsequent-day consequences like tiredness and sleepiness. 2C-G-5 was also the longest-lasting drug included in PiHKAL based on its specified duration.
