Kaizen – Nitro-Zen Live Rosin Rosin, turbocharged. When rosin is washed and pressed, some of the plant's terpenes get lost. Kaizen's Nitro-Zen line uses a nitrogen-based process to capture those cannabis terpenes and put them back into their solventless live rosin. That gives you way more flavor and a stronger entourage effect. Each blend is hand-paired by Kaizen's founder, so every jar is a one-of-a-kind flavor combo, and every dab is loud, juicy, and full-spectrum.
