Grease Monkey potency: THC, CBD and terpenes from 576 lab tests

In 576 state lab tests, Grease Monkey flower had a median total THC of 22.84%, with the middle half of results between 19.39% and 27.08%; 36.6% of tests reached 25% or more.1 Of the 43 strains in our dataset with at least 100 tests, 8 had higher medians.1 CBD is negligible, and β-caryophyllene leads the terpenes by median, ahead of limonene and α-humulene: two of the three terpenes Leafly lists (caryophyllene, limonene and myrcene).1,2

How published THC figures compare

Strain databases publish a single figure or a range: Leafly lists 22% THC (with 1% CBG) and AllBud 25–27%; Weedmaps’ page, filed under Grease Bucket, gives none.2,3,4 Seed sellers quote 20–22% for Seeds Here Now’s packs of the original Exotic Genetix seeds, "above 20%" for Nirvana Seeds’ version, up to 24% for Zamnesia’s and up to 30% for United Cannabis Seeds’.5,6,7,8 In state lab results, half of Grease Monkey flower tested above 22.84% and one in ten above 28.85%, so AllBud’s 25–27% falls in the upper half of the lab range, below the top quarter of results (from 27.08%), and the 30% claim is above nine in ten lab results.1 The highest single result in our data was 32.69%.1 AllBud lists 1% CBD and United Cannabis Seeds about 2%, but none of the 367 tests that reported CBD reached 1%; the highest was 0.24%.1,3,8

Results differ sharply by market: among states with at least 10 tests, the median ran from 19.88% in Nevada (39 tests) to 27.12% in Maryland (241). One Maryland lab supplied 205 of the 576 tests (35.6%); their median was 27.61%, against 20.82% for all other tests, and the other 36 Maryland tests had a median of 17.99%. In the years when that lab supplied more than half of the tests (2018, 2019 and 2020), the yearly median ran from 25.52% to 28.28%; in the other years with at least 50 tests (2021, 2022 and 2023) it ran from 20.37% to 23.51%.1

Limits of this data

  • Coverage is uneven. Maryland (241), Michigan (206), Washington (61) and Nevada (39) supply 547 of the 576 tests, which date from 2016 to 2024; Oregon and Rhode Island results carry no product names and could not be matched.
  • Some labs report higher THC than others, so we publish medians and middle ranges rather than maxima. One Maryland lab accounts for 35.6% of these tests (34 labs in total), and its median, 27.61%, is well above the 20.82% of all other tests.
  • Terpene medians come from 55 tests with individual terpene values, 39 of them from Nevada labs. Maryland reports only total terpenes (235 tests), and the Michigan and Washington tests carry none.
  • We matched names strictly: "Grease Monkey", "Greasemonkey" and numbered labels such as "Grease Monkey #2" count, but crosses, backcrosses and names that add another word (for example "Mendo Breath x Grease Monkey") are excluded and counted, and duplicate certificates are removed.
