Part I Heavy Metals Testing

1.1 · Why it mattersWhy heavy metals must be tested in a mineral product

Shilajit is a geological exudate: it forms over thousands of years from the compression and microbial decomposition of plant matter inside high-altitude rock. Because it originates in the earth, it can absorb trace elements from the surrounding geology, including measurable amounts of heavy metals. This is not unique to shilajit, arsenic, lead, cadmium, and mercury are routinely detected in rice, apple juice, leafy vegetables, seafood, and organic produce.

The question is never whether trace elements are present at all, in a mineral-origin product, trace amounts are expected. The relevant question is whether levels fall within the ranges toxicology considers safe for chronic daily exposure. The FDA, WHO, AHPA, and USP each publish Permitted Daily Exposure (PDE) limits that answer exactly this.

1.2 · MethodologyICP-MS via AOAC official methods

Heavy-metal analysis used Inductively Coupled Plasma Mass Spectrometry (ICP-MS), following AOAC Official Methods 2011.19, 993.14, and 2015.01. ICP-MS is the internationally recognised gold standard for trace-element detection in food and supplements: it atomises the sample in an argon plasma at roughly 6,000-10,000 °C, then separates elements by mass-to-charge ratio at parts-per-billion (ppb) precision. Published validation confirms recovery of 92.2-103.1% across As, Cd, Pb, and Hg matrices, with repeatability below 3.55%. The Madison facility holds accreditation number 2918.01 under the ILAC Mutual Recognition Arrangement.

1.3 · ResultsActual heavy-metal results, Lot 2232-132

Reported in COA #4545687-0, Elements by ICP Mass Spectrometry, serving size 300 mg:

Source Eurofins COA #4545687-0, Lot 2232-132, tested June 2024. Method: ICP-MS per AOAC 2011.19, 993.14, 2015.01 (Modified).

All five elements tested below their specification limits. The safety margin is substantial: arsenic, the highest measured element, came in at 19.3% of its spec limit, leaving an 80.7% margin. Mercury registered at just 0.204% of its limit.

1.4 · In practiceWhat these values mean at maximum daily use

Assuming two servings daily (600 mg total) against USP <2232> Permitted Daily Exposure limits:

Even at maximum daily use, no element approaches its regulatory daily-exposure threshold.

1.5 · ContextHeavy metals in everyday foods

The FDA’s Total Diet Study found arsenic in 43% of all food samples tested, with individual seafood readings reaching 10,900 ppb. A Consumer Reports investigation of 45 fruit juices found measurable heavy metals in every single product, and organic products showed no advantage over conventional ones. A 300 mg serving of resin is a fraction of the food mass in a glass of juice or a bowl of rice, so absolute daily exposure from this product is demonstrably low by comparison.

Part II Microbiology Testing

Microbial contamination, pathogenic bacteria, mold, and yeast, is an independent safety dimension, distinct from heavy metals. Testing follows USP current-revision chapters 2021 and 2022. This product has been tested across two rounds, with the 2024 evaluation (COA #4545687-0) and the 2026 confirmation (COA #5381929-0) showing consistent results.

2.1 · May 2026COA #5381929-0, Eurofins Micro Lab, Madison

2.2 · June 2024COA #4545687-0, extended pathogen panel

What “suitability” means: before reporting a valid absence for E. coli or Salmonella, the lab must first confirm the test conditions can detect those organisms in this specific matrix. A PASS on both suitability tests means the absence result is a true negative, not a testing artifact. The critical finding, absence of all pathogens, is consistent across both testing periods.

Part III Fulvic Acid Content

COA #5381929-0 (May 2026) reports Fulvic Acid at 34.52 g/100g (34.52% by dry weight) for Lot 2232-132, measured by Eurofins Analytical Services India using the IRXNK fulvic acid method, a specialised extraction-based protocol.

Fulvic acid is the low-molecular-weight fraction of humic substances, distinguished from heavier humic acid by its solubility in both acid and alkaline conditions. It carries a high density of oxygen-containing functional groups (carboxyl, carbonyl, phenolic hydroxyl) that underlie its documented ability to bind minerals, transport nutrients across cell membranes, and participate in electron transfer. A result of 34.52% means slightly more than one-third of the resin’s dry mass is measurable fulvic acid, substantial for a natural mineral-origin product.

Part IV Adulterant Screening (Amazon Certification)

COA #4545687-0 includes a targeted LC-MS/MS screen for 28 sexual-enhancement adulterants, synthetic PDE5 inhibitors (sildenafil, tadalafil, vardenafil, and 25 analogs) occasionally found in illegally adulterated supplements.

Reporting limit: 50 ppm per compound. The complete Amazon Certification panel, Adulterants, Contaminants, Pathogens, Microbiological, GMP, Content Claims, and Label Review, returned an Overall Certification: PASS.

Part V Testing Laboratory Credentials

All COAs were issued by Eurofins Food Chemistry Testing Madison, Inc., 6304 Ronald Reagan Ave, Madison, WI 53704, authorised by Edward Ladwig, President. Eurofins operates one of the world’s largest testing networks, over 900 laboratories across 50+ countries. The Madison facility holds accreditation number 2918.01 under the ILAC Mutual Recognition Arrangement, so its results are recognised by regulatory authorities across participating countries.

ISO/IEC 17025 accreditation requires:

• External audits by an independent national accreditation body (A2LA in the U.S.)
• Demonstrated proficiency through inter-laboratory comparison programs
• Documented and validated analytical methods for each test performed
• Measurement-uncertainty statements available on request
• Results that carry evidentiary weight in regulatory enforcement

Chain of custody is documented across every COA header: Project IDs assigned by Global Wellnest Distribution Inc., Eurofins Sample IDs assigned independently by the lab, plus Receipt, Login, and Date-Started fields. The manufacturer did not conduct or oversee the testing.

Part VI Comprehensive Results Summary

Every parameter, its Lot 2232-132 result, the governing regulatory reference, and its real-world comparison context, on one page.

Part VII DBP Verification & The Third Layer

Fulvic acid analysis establishes what is in the product. Heavy-metals testing establishes it is safe. DBP verification establishes it is authentic. Dibenzo-α-pyrones are oxygen-heterocyclic compounds produced exclusively through the geological humification and pressurisation that creates shilajit resin. Their presence, and specific molecular profile, is the most specific fingerprint available for distinguishing authentic resin from generic humic concentrates or reconstructed imitations.

DBP testing for Lot 2232-132 is published in a separate report, forming the third pillar alongside the safety and cleanliness data above.

Verification · 5 stepsHow to verify your lot

Every jar carries a Lot Number printed on the label. The results here apply specifically to Lot 2232-132. To verify any lot:

1. Match the Lot Number on your label to the COA header.
2. Confirm the laboratory name, Eurofins Food Chemistry Testing Madison, Inc.
3. Check the accreditation number, 2918.01 (ILAC MRA).
4. Note the Receipt and Test-Start dates, which confirm the COA corresponds to actual batch testing.
5. Review the numeric results, not just the pass/fail checkbox, but the measured values against the spec limits.
