Providing nitrogen and calcium: Calcium cyanamide products not only provide the nitrogen element needed by plants, but also provide calcium, which is crucial for plant growth and development. Calcium is an important component in building plant cell walls and can enhance the structural stability of plants.


Creatine is an amino acid derivative naturally produced in the human body, composed of three amino acids: arginine, glycine, and methionine. Creatine is synthesized in the human liver and can also be obtained from food. It can rapidly increase muscle strength, accelerate fatigue recovery, and improve explosive power. The more creatine stored in the human body, the stronger the person's strength and athletic ability.
