Quality Control

Quality Control Team:

  • Quality Inspection in every step.
  • Professional quality control staff to avoid unqualified products flowing to customer.
  • Strict inspection on raw material, production, and delivery.
  • Full series of equipments in lab.
  • Follow ISO 9001 standards strictly.
  • Continuous Efforts for improvement, seeking higher quality level.​​​​

The Testing Procedures:

The Factory have hundreds of tests that are used to determine purity, potence and quality of

the materials and end products all of which utilize state of the art equipment which ensures

complete accuracy.

Product Testing:

At any point during production a product may be tested. If it doesn't meet regulation standard

the batch is immediately withdrawn and in the final stages of production the product must

undergo the final quality control procedures before it may receive the 'pass' grading which

releases it for sale.

Repeated Checks:

As well as the standard checks the raw materials and finished products are tested for heavy

metal content. In recent years there has been a significant problem with the underground

Factory's producing poor quality products that are filled with toxic heavy metals. This is because

they are no licensed and therefore under no obligation to test for these; when you buy cheap

products - you pay the price with your health.

While the level of heavy metals found in the raw materials may be acceptable, once it has

been mixed with other compounds and reactions taken place these levels can change. Testing

throughout the production process therefore ensures our Factory only ever release the safest and

most effective compounds.
