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the batch is immediately withdrawn and in the final stages of production the product must 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