Pro secrets

The secret to unlocking the full potential of C99 lies in temperature control. To preserve its delicate Caryophyllene terpenes, vaporize at 266°F (130°C) rather than combusting. This triggers the entourage effect, blending its 30% THC with secondary cannabinoids. It offers a balanced transition, making it great for social afternoons, hiking, or relaxing after work. Beginners should start with a single inhalation due to its fast-acting onset, while seasoned users can appreciate its deep, multi-layered terpene depth.
