CBG vs CBD
Two compounds that get compared constantly and confused almost as often. Here is the structural difference, where each one comes from, and what our own lab reports measure for each.

The structural difference
CBG
CBGA is the precursor from which the plant synthesises THCA, CBDA and CBCA. Whatever CBGA is not converted remains, and heating it yields CBG. That is why mature flower usually shows only a small residual CBG percentage: most of the CBGA has already been spent building other cannabinoids.
CBD
CBD is produced by decarboxylation of CBDA, which the plant synthesises from CBGA. It is the cannabinoid hemp cultivars are most commonly bred to maximise.
What that means on a label
CBG is sometimes called the "mother cannabinoid" for that reason. High-CBG material generally comes from cultivars bred to interrupt that conversion, or from early harvest.
CBD content is the headline figure on most hemp products, but it says nothing about the rest of the profile. Read it alongside the minor cannabinoids to understand what you are actually buying.
Side by side, as measured
| Products detected | Lowest | Average | Highest | Labs | |
|---|---|---|---|---|---|
| CBG | 88 | 0.001% | 0.296% | 3.693% | 20 |
| CBD | 187 | 0.001% | 3.697% | 28.395% | 25 |
These are catalogue ranges, not a controlled comparison. Product form moves these numbers more than the compound does, which is exactly why a single certificate tells you more than any average.

Common questions
What is the difference between CBG and CBD?
CBG is decarboxylated CBGA — the compound the plant builds its other cannabinoids from. CBD is the most abundant non-intoxicating cannabinoid in hemp. They are distinct molecules and a certificate of analysis reports them separately.
Is CBG stronger than CBD?
Measured content is the only comparison we can make from lab data. In this catalogue CBG shows 0.001% to 3.693% across 88 products, and CBD shows 0.001% to 28.395% across 187 products. Those ranges reflect product form as much as the compound, so compare individual certificates rather than category averages.
How is CBG formed compared with CBD?
CBGA is the precursor from which the plant synthesises THCA, CBDA and CBCA. Whatever CBGA is not converted remains, and heating it yields CBG. That is why mature flower usually shows only a small residual CBG percentage: most of the CBGA has already been spent building other cannabinoids. By contrast, cBD is produced by decarboxylation of CBDA, which the plant synthesises from CBGA. It is the cannabinoid hemp cultivars are most commonly bred to maximise.
Which one does hemp law actually measure?
Federal hemp law is written around Delta-9 THC, with newer language using Total THC, which adds the THCA that converts on heating. Other cannabinoids are treated separately and state by state, so check the position where you are.
