Why We Publish Our Lab Results
The shilajit market is crowded with vague claims and no proof to back them up. We took a different approach: every batch of Muscle Warehouse Himalayan shilajit is sent to independent, accredited laboratories — not a lab we run ourselves, and not one that has any say in how the results are described. What's published on this page is exactly what came back.
We currently hold results from PCSIR Laboratories Islamabad, a government-accredited facility under Pakistan's Ministry of Science & Technology, and Eurofins UK, one of the world's largest independent testing networks. Together, these give you an unfiltered look at the purity of the shilajit that goes into our resin, drops, and capsules.

What "Not Detected" Actually Means
Shilajit forms over centuries in compressed rock layers, which means it can absorb whatever is naturally present in its environment — including trace heavy metals. This is exactly why testing matters for any pure shilajit UK buyers are considering. Where our results show "Not Detected," it means the specific heavy metal fell below the laboratory's detection threshold entirely, not that it wasn't tested for.
Mercury was measurable in both reports, at 0.09 ppm (PCSIR) and 0.032 mg/kg (Eurofins) — both low readings, though we'd recommend having your compliance team confirm these sit within current UK food supplement contaminant regulations before stating a pass/fail claim publicly.
Fulvic Acid: Our Stated Specification
Fulvic acid is the compound most closely associated with shilajit's reputation — it's considered the carrier molecule that helps the body absorb the trace minerals shilajit is known for. Muscle Warehouse Himalayan shilajit contains 75% fulvic acid, among the highest available in the UK market.
How the Testing Works
PCSIR Islamabad tested moisture, ash, volatile matter, and solubility using AOAC International's standard methods, alongside heavy metal screening via Atomic Absorption Spectrophotometer (AAS) — a widely used, reliable method for trace metal detection.
Eurofins UK tested heavy metals using ICP-MS (Inductively Coupled Plasma Mass Spectrometry), considered one of the most sensitive methods available for detecting trace-level contaminants, and tested ash content separately under their own reference method.
Neither lab had any role in how these results are presented on this page — the numbers above are reported as issued.
Sourced From the Himalayas, Tested Before It Reaches You
Our Himalayan shilajit is sourced from altitudes of 15,000–18,000ft, using high-quality raw stone that's ultra-purified using traditional methods — no synthetic additives, no reconstituted extract. Every batch goes through this same testing process before it's made available across our resin, drops, and capsule range.

A: Yes. Muscle warehouse shilajit is tested by PCSIR Laboratories Islamabad (a Pakistani government-accredited facility) and Eurofins UK. Full certificates are published above.
Q: What does "Not Detected" mean on a heavy metal test?
A: It means the result was below the laboratory's detection limit — the specific detection thresholds are listed under each report.
Q: Is Muscle Warehouse shilajit safe?
A: Our shilajit undergoes independent testing for heavy metals and other purity markers, with results published transparently on this page. As with any supplement, consult a healthcare professional if you have concerns specific to your health.
Q: Where does Muscle Warehouse shilajit come from?
A: It's sourced from altitudes of 15,000–18,000ft in the Himalayas.
