2C-G is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin, 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 homologues (see below) 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. There are 209.284 grams of C12H19NO2 per mole (209.284 g/mol).

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-enhancher" [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-2 and 2C-G-4, are possible to synthesize in principle but impossible or extraordinarily difficult to do so in practice.

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-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-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 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 persecuted 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.
