The best lab-tested concentrates in New York (2026)

The short answer

Next come Heavy Hitters (85.8) and Rythm (77.8). 6 of the 14 concentrate brands indexed in New York have the 10 or more certificates a ranking needs, and every one is scored by the same published consistency formula: testing depth, record length, pass rate, batch-to-batch THC variation, panel breadth and recall history.

The ranking

How we ranked

Each brand's score is the index's published consistency score (methodology), run over only that brand's finished concentrates in this market: testing depth, how long the record runs, pass rate, batch-to-batch THC variation within each product line, pesticide panel breadth, public certificate links, and recall history. Because it uses one category, the number can differ from the overall score on a brand page. Population: 168 finished concentrates with laboratory certificates in this index. A brand needs 10 to be ranked. Limits: this ranks what the index holds, not every brand on shelves; a brand that is not indexed is not ranked, which says nothing about its quality.
