Gastro Pop is Compound Genetics' cross of Apples and Bananas and Grape Gas. It landed as one of the loudest fruit-and-fuel releases of the modern era: skunky grape and fizzy purple candy on near-black flower, with caryophyllene, limonene, and myrcene running the profile. It skews calming, with a serious appetite kick attached.
Where It Comes From
Compound Genetics was founded in 2017 in Portland, Oregon by Christopher Lynch, who had been growing for more than 15 years before starting the company. Gastro Pop's story runs through its first parent.
Apples and Bananas came out of one of Compound's Jet Fuel Gelato seed collections and was released in 2019 as the first collaboration between Compound and Berner's Cookies. Lynch has described the split of labor plainly: "I created the strains, gave them to him, and he created the marketing." He also pushed back on the idea that celebrity alone carried it, saying people liked it because the profile was genuinely unique.
Gastro Pop took that fruit and crossed it back into Compound's own gas, then became a platform in its own right. The Gastro Pop seed collection now includes Gastro Pop S1, Banana Cream Pop, and Perzimmon, a working sign that the cultivar earned a place in the breeding program rather than just on menus.
The Cross
Compound Genetics is the breeder. The published cross is Apples and Bananas x Grape Gas, the second parent also written Grape Gasoline. Grape Gas is commonly published as Grape Pie x Jet Fuel Gelato, grape candy with kerosene underneath. Apples and Bananas traces back to Compound's own Jet Fuel Gelato line and carries apple, banana, and cherry over gas.
The pairing is not subtle by design. Both parents are loud, both carry Jet Fuel Gelato, and the cross stacks fruit intensity on fuel intensity instead of trying to balance them.
The result reads spicy and sugary, grape and purple and fizzy, with apple and pepper coming through behind it. Caryophyllene, limonene, and myrcene lead: the pepper, the citrus brightness, and the heavy base. That fizzy note is the useful detail. Gastro Pop does not sit flat like grape candy, it reads carbonated, with a sour-sharp edge that keeps the sweetness from going syrupy.
Flower is known for deep purple running toward near-black, dense golf-ball-sized buds, and a thick resin coat, with color depending on phenotype and finishing conditions rather than the label. It logs as mostly calming, with relaxation, arousal, and appetite at the top, and licensed producers generally classify it as hybrid or indica-dominant. It fits an evening slot, particularly one that ends in food.
Potency is where the name gets slippery. The broader range runs 23 to 30 percent, with original Gastro Pop #5 clones testing 27 to 30 and the S1 seed line landing lower at 23 to 27. That is a real difference between the clone-only cut and the seed version rather than batch noise, and it is worth knowing before you compare two jars carrying the same name.
What It Left Behind
The footprint is genetic and commercial: a signature Compound release, an established parent for at least three named descendants in Compound's own catalog, and a widely licensed cultivar in regulated markets outside California.
The High Rise Take
Gastro Pop is Compound's Apples and Bananas x Grape Gas: purple flower, fizzy grape candy, and gas that does not hide. Ask whether you are getting the #5 clone or the S1. For the fruit half on its own, go to Apples and Bananas.
