CBG vs CBD: what’s the difference?
CBD is made when CBDA synthase acts on CBGA and heat then decarboxylates the CBDA. CBG is the parent acid itself after decarboxylation, not a CBD analog. They come from the same plant pathway but sit on different branches, have different ring structures and carry different CAS numbers (CBG 25654-31-3, CBD 13956-29-1). CBD has a large human literature; CBG has one acute trial.
| CBG | CBD | |
|---|---|---|
| CAS | 25654-31-3 | 13956-29-1 |
| Formula | C21H32O2 | C21H30O2 |
| Made from | CBGA, decarboxylated | CBDA, decarboxylated |
| Role | Parent (neutral) | CBDA-synthase branch |
| Peregrine SKU | cbg-isolate | Monograph only; not sold here |
Origin
Formulators pick CBD when they need the large public literature and a commodity. They pick CBG when the brief is the mother cannabinoid, a different ring, or a specification that is not CBD.
Established
- Separate CAS, formula, and biosynthetic step.
- Both treated as non-intoxicating relative to Δ9-THC.
Not yet
- A head-to-head human trial of the two.
- Swapping one isolate for the other in a process without rewriting the specification.
Questions
Is CBG better than CBD?
Neither is better; they are different molecules with different chemistry and different evidence. Buy the one your specification names.
Can I buy both wholesale?
CBG isolate, yes, from 5 g to 100 kg; contact us for pricing. CBD is documented on the learn pages but is not currently one of our wholesale isolates.
Evidence language follows CBG Atlas (Peregrine-funded; editorial independence). Not medical advice. Not a disease claim.
