PAH4 and shilajit: why are these analyses becoming important?
PAH4 analyses are used to detect certain polycyclic aromatic hydrocarbons (PAHs) in shilajit.
They provide an additional level of control to more well-known analyses such as heavy metals or microbiology.
The shilajit market has grown significantly in recent years. However, not all brands communicate with the same level of transparency about the analyses actually performed.
Among the most technical controls is the analysis of PAH4. Little known to the general public, they can nevertheless become an interesting indicator when trying to assess the credibility of a product.
What does PAH4 mean?
PAH4 stands for Polycyclic Aromatic Hydrocarbons 4. In French, it is generally referred to as HAP4: hydrocarbures aromatiques polycycliques.
The term refers to a group of four compounds often monitored in certain food safety controls:
- benz(a)anthracene;
- benzo(a)pyrene;
- benzo(b)fluoranthene;
- chrysene.
Important: PAH4 analyses do not replace traditional controls such as heavy metals or microbiology. They are complementary.
Why analyze PAH4 in shilajit?
Shilajit is a complex organo-mineral substance. Like many natural materials, its quality cannot be evaluated solely on marketing claims.
PAH4 analyses allow for an additional check on certain potential organic contaminants.
Saying that a shilajit is "pure" is not enough.
The real question is: what contaminants have been sought, on which batch, with which laboratory, and what were the results?
PAH4, heavy metals, and microbiology: what are the differences?
| Analysis |
What it checks |
Why it's useful |
| Heavy metals |
Lead, mercury, arsenic, cadmium depending on controls. |
To evaluate certain mineral contaminants. |
| Microbiology |
Yeast, mold, bacteria, or germs tested. |
To control certain microbiological risks. |
| PAH4 |
Targeted polycyclic aromatic hydrocarbons. |
To add a control on certain organic contaminants. |
Why do few brands talk about PAH4?
PAH4 is a technical subject. Most brands prefer to communicate on simpler themes such as "Himalayan origin," "purity," or "fulvic acid."
However, PAH4 analyses can become an interesting indicator of transparency when they are clearly published with:
- an identifiable batch;
- an indicated laboratory;
- consultable results;
- analyses consistent with the product sold.
Strategic reading: when a brand publishes this type of analysis, it accepts a higher level of transparency than the market average.
How to read a PAH4 analysis on a certificate?
A certificate of analysis should not be read diagonally. Several elements deserve to be checked.
| Element |
Why it's important |
| The batch number |
The certificate must correspond to the product actually purchased. |
| The laboratory |
The laboratory must be identifiable. |
| The molecules tested |
The four PAH4s must be clearly indicated. |
| The results |
They must be legible and understandable. |
| The report date |
It helps verify the currency of the analyses. |
Do PAH4 analyses influence the price of shilajit?
Yes, indirectly. Complementary analyses represent an additional cost for brands that choose to strengthen their controls.
This can explain part of the difference between:
- a product with very little documentation;
- and a product associated with detailed batch certificates.
Price alone is not enough.
What really matters is what is controlled, published, and verifiable.

FAQ — PAH4 and shilajit
What does PAH4 mean in shilajit?
PAH4 refers to four polycyclic aromatic hydrocarbons sometimes sought in certain food safety controls.
Why are PAH4 analyses important?
They provide an additional control over certain potential organic contaminants.
Do PAH4s replace heavy metals?
No. PAH4 analyses complement heavy metal and microbiological controls.
How to verify a PAH4 analysis?
You need to check the batch, the laboratory, the molecules analyzed, and the consistency of the certificate with the product purchased.
Do all brands publish PAH4 analyses?
No. Few brands clearly highlight this type of analysis in their public certificates.
Conclusion: PAH4 analyses represent an additional level of control that can help better evaluate the transparency and seriousness of a shilajit.
