2C-G is a psychedelic phenethylamine of the 2C family. First synthesized by Alexander Shulgin,[1] 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, 2C-G and its homologs 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.[1] 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 homologs 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-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.


Legal status


As of October 31st, 2016; 2C-G is a controlled substance (Schedule III) in Canada.[2]

United Kingdom

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

=United States

2C-G and all of its homologs are unscheduled in the United States, but possession and sales of 2C-G and homologs might be prosecuted under the Federal Analog Act because of their close structural similarities to 2C-B, which is a Schedule I controlled substance.
