Manufactured by FDA-registered and compliant enterprises. The manufacturing environment (located in bonded areas) meets the requirements of the current GMP (Good Manufacturing Practice) for pharmaceutical production; in addition, the manufacturing environment has obtained the safety certification for management systems from UL, and has passed the joint process and quality certification system jointly implemented by two authoritative institutions, NPA and UL.

Raw material sealing test, pre-manufacturing process test, third-party submission and inspection of finished products, and quarantine and inspection in China's bonded areas – all these links form a strict multi-level quality control system.

The core raw materials of each product are supported by clinical data, patents, and authoritative academic materials.

The brand and its factories hold stringent standard certifications and have patent support. Ensuring product quality and safety is the red line we uphold, and evidence-based effectiveness is the upper limit of our pursuit.
