The Short Answer: Yes, Shilajit Lab Reports Can Be Faked
Certificate of Analysis (COA) fraud is more common in the supplement industry than most buyers realise. With Shilajit specifically — a product where quality is invisible to the naked eye and lab data is the only reliable verification tool — fake or manipulated lab reports are a serious and growing problem.
Understanding how COA fraud works is the first step to protecting yourself as a buyer.
How Shilajit Lab Report Fraud Actually Happens
There are four primary methods used to deceive buyers with fraudulent lab documentation:
1. Fabricated COAs
A document is created from scratch using design software, mimicking the layout of a real laboratory report. The lab name, logo, and accreditation number may be entirely invented — or copied from a legitimate lab without authorisation. The results shown have no connection to any actual test.
2. Recycled COAs
A genuine COA from one batch or one product is reused across multiple batches, different products, or even different brands. The document is real, but it does not represent the product being sold. This is one of the most common forms of COA misuse.
3. Altered COAs
A legitimate COA is digitally edited — typically to change the fulvic acid percentage, remove a failed heavy metals result, or update a date. The lab name and accreditation details are real, but the results have been manipulated.
4. Unaccredited or Fictitious Laboratories
Some brands commission testing from laboratories that are not ISO/IEC 17025 accredited — or that do not exist as verifiable entities. The COA looks professional but carries no scientific weight because the issuing lab has no recognised accreditation.
Red Flags: Signs a Shilajit COA May Not Be Genuine
Before trusting any lab report, check for these warning signs:
- No accreditation number listed — Every legitimate ISO-accredited lab includes its accreditation number on reports
- No batch or lot number — A genuine COA is tied to a specific production batch; generic documents are not
- No test methodology cited — Real lab reports specify the analytical method used (e.g. UV-Vis spectrophotometry for fulvic acid)
- Unusually high fulvic acid figures — Results above 60% are outside the realistic range for purified Shilajit resin (40–55% by dry weight is the credible benchmark)
- No heavy metals panel — Legitimate supplement COAs include lead, arsenic, mercury, and cadmium results
- PDF that cannot be verified online — Many accredited labs provide report verification portals; if a COA cannot be cross-referenced, treat it with caution
- Lab name that returns no verifiable results — Search the lab name against national accreditation body databases; if it doesn’t appear, the lab may not be legitimate

How to Independently Verify a Shilajit COA
Follow these steps to check whether a lab report is genuine:
Step 1: Identify the laboratory name and accreditation number
These should appear clearly on the COA header or footer.
Step 2: Search the accreditation body database
In the UK, use UKAS (ukas.com). In the US, use A2LA (a2la.org) or ILAC (ilac.org) for international labs. Search the lab name and accreditation number to confirm it is a registered, active laboratory.
Step 3: Check the scope of accreditation
Confirm the lab is accredited specifically for food, supplement, or nutraceutical testing — not just environmental or industrial testing.
Step 4: Match the batch number
The batch or lot number on the COA should match the batch number on the product packaging. If a brand cannot provide this match, the COA may not represent the product you are buying.
Step 5: Contact the laboratory directly
If in doubt, contact the lab directly with the report reference number and ask them to confirm the report is genuine. Legitimate labs will confirm authentic reports.
What a Genuine Eurofins COA Looks Like
Eurofins Scientific is one of the world’s largest ISO/IEC 17025 accredited testing networks, operating over 900 laboratories across 60 countries. A genuine Eurofins COA includes:
- Eurofins laboratory name, address, and contact details
- ISO/IEC 17025 accreditation number (verifiable via the relevant national accreditation body)
- Unique report reference number
- Client name and product description
- Batch or lot number
- Test parameters with results, units, and limits
- Analytical methodology for each parameter
- Authorised signatory name and date
Every batch of Golden Shilajit Official resin is tested by Eurofins Scientific. Our COAs are batch-specific, publicly accessible, and verifiable. You can review them here: Golden Shilajit Official Lab Reports
Why This Matters for Shilajit Buyers Specifically
Shilajit sourced from unverified suppliers can contain elevated levels of heavy metals including lead, arsenic, and mercury — contaminants that are invisible in the product and only detectable through laboratory analysis. A fake or recycled COA provides false reassurance while the buyer consumes a potentially unsafe product.
This is not a theoretical risk. Independent testing of Shilajit products sold on major marketplaces has found heavy metal levels exceeding safe limits in products that claimed to be lab tested.

The Verification Checklist: 7 Questions to Ask Before Trusting a Shilajit COA
- Is the issuing laboratory ISO/IEC 17025 accredited and verifiable in a national database?
- Does the COA include a unique accreditation number?
- Is the COA batch-specific, with a lot number that matches the product packaging?
- Does the report include a full heavy metals panel (lead, arsenic, mercury, cadmium)?
- Is the fulvic acid percentage within the realistic 40–55% range?
- Is the analytical methodology cited for each test parameter?
- Can the report be verified directly with the laboratory using a reference number?
If any answer is no, the COA should not be trusted as proof of product quality or safety.
