Certificate of Analysis

Transparency matters. Every batch of StoneBlood Shilajit is tested by an independent, accredited laboratory for microbial safety, heavy metals, and purity. Below are our most recent results, issued by Analytical Resource Laboratories (ARL) — an ISO/IEC 17025:2017 accredited lab.

What the results show

Our latest panel came back clean across the board: no detectable E. coli, Salmonella, Staph, coliforms, yeast, or mold, and heavy metals (arsenic, cadmium, mercury, lead) all measured at trace levels well within safe limits for a mineral resin. This is what real, verifiable purity looks like.
