2C-G is a psychedelic phenethylamine of the 2C family. First synthesized by Alexander Shulgin, it is sometimes used as an entheogen. It has structural and pharmacodynamic properties similar to 2C-D and Ganesha. Like many of the phenethylamines in PiHKAL (Phenethylamines i Have Known And Loved), 2C-G and its homologues have only been taken by Shulgin and a small test group, making it difficult to ensure completeness when describing effects.

2C-G is 3,4-dimethyl-2,5-dimethoxyphenethylamine, with the formula C12H19NO2.

Dosage and effects

In Shulgin's book PiHKAL, the dosage range is listed as 20 to 35 mg. Effects are similar to the related Ganesha, and are extremely long lasting; the duration is 18–30 hours. Visual effects are muted or absent, and it is described in PiHKAL as an "insight-enhancer".[1] Unlike other members of the 2C family, 2C-G is nearly as potent as its amphetamine cousin.


Several homologues of 2C-G were also synthesized by Shulgin. These include 2C-G-3, 2C-G-5, and 2C-G-N. Some, such as 2C-G-1, 2C-G-2, 2C-G-4, and 2C-G-6 are possible to synthesize in principle but impossible or extraordinarily difficult to do so in practice.

2C-G-2 CAS: not available

The synthesis of this compound has not been reported

2C-G-3 CAS: 207740-19-0

Dosage: 16–25 mg
Duration: 12–24 hours
Effects: Some visual effects. General euphoria with an underlying sense of paranoia.

2C-G-4 CAS: 952006-59-6

Synthesized but not tested.

2C-G-5 CAS: 207740-20-3

Dosage: 10–16 mg
Duration: 32–48 hours
Effects: Similar to 2C-B for some users. General euphoria (sometimes followed by irritability), often leading to tiredness (likely due to duration).

2C-G-6 CAS: not available

The synthesis of this compound has not been reported

2C-G-N CAS: 207740-21-4

Dosage: 20–40 mg
Duration: 20–30 hours
Effects: Stimulation similar to that caused by amphetamines. General sense of unease or unfriendliness for most. 2C-G-N is sometimes called 2C-NPH due to the naphthalene portion of the molecule.



2C-G and all of its homologues are unscheduled and uncontrolled in the United States, but possession and sales of 2C-G (and homologues) will probably be prosecuted under the Federal Analog Act because of their structural similarities to 2C-B.

2C-G and all other compounds featuring in PiHKAL are Class A drugs in the United Kingdom.
