GMO Cookies is a hybrid strain that comes from a cross of GSC with Chemdawg. You may also see it sold as Garlic Cookies, GMO Garlic Cookies. People who try it most often describe feeling relaxed, sleepy and euphoric.
Across 395 public lab tests of GMO Cookies flower between 2020 and 2024, the median result was 27.3% total THC, with half of all samples falling between 24.1% and 30.1%. CBD is typically negligible (under 0.5%). That puts it at the strong end of the market, so newer consumers should start low. Potency varies by grower and batch, so always check the label.

Myrcene is known for earthy, musky notes with a ripe-fruit edge, while limonene adds bright citrus-peel freshness. Total terpene content measured a median of 2.1%. On the palate, people pick out pungent, chemical and diesel.
