This page collects all available Certificates of Analysis, third-party lab test results, and testing transparency information for Fristfei products in the ShilajitDB database. Data is sourced from publicly available brand documentation and independent research. We do not accept payment from brands and our assessments are not influenced by commercial relationships.
COA status
Public — directly accessible without contacting the brand. The strongest signal.
On request — available but requires asking; cannot be independently verified without effort.
None — no Certificate of Analysis is available.
Third-party lab
The named laboratory that performed testing. Only a named, independent, ISO 17025-accredited lab earns full credit in our grading. "In-house" or unnamed labs do not count as third-party.
Heavy metals
Confirmed — the COA shows actual numeric concentrations for lead, arsenic, mercury, and cadmium.
Claimed — the brand states testing was done but specific numeric values are not publicly available.
COA document review notes
COA reviewed September 2026. Brand-headed certificate (FRISTFEI) carrying the Eurofins logo, certificate no. AR-24-R2-019030-01, sample code 727-2024-00024745, report date 6 Nov 2024. Heavy metals (As, Cd, Pb, Hg) reported as PASS with no concentrations; fulvic acid stated as >75%. No laboratory address, accreditation, methods or limits of quantification, and no batch or lot code for the retail product, so it is recorded as a brand-issued document rather than a laboratory report.
About this data
COA status is assessed based on publicly available documentation. A certificate is marked "Public" only when it is directly accessible (via a link or embedded on the brand's website) without needing to request it. Heavy metals are marked "Confirmed" only when the COA includes actual numeric concentrations (e.g., Pb: 0.15 ppm) rather than a pass/fail stamp. Testing laboratory names are recorded as stated in the COA document; we do not independently audit lab accreditation for every entry.
