Laboratory Testing
Quality & Transparency
At PureSpec Lab, we believe customers should have clear and accurate information about the products they purchase. Below is a summary of the laboratory documentation supplied by our manufacturing partner for the NMN material associated with our product.
How the Testing Was Arranged
The testing was commissioned by Huaqing (Xi'an) Natural Ingredients Co., Ltd and conducted by SGS-CSTC Standards Technical Services (Shanghai) Co., Ltd.
Because Huaqing commissioned the analysis, its name appears as the client on the SGS report. PureSpec Lab did not directly commission this test and is not affiliated with or endorsed by SGS.
