Shilajit is a hard product to judge by looking at it. Counterfeits and heavily adulterated resins exist, and a convincing black blob proves nothing. Here are the home checks people use, and the honest limits of each.
Five home checks
- Dissolves in warm water. Real resin dissolves into a clear amber-brown solution. Heavy sediment or a gritty residue is a warning sign.
- Behaves with temperature. Good resin is soft and tacky at room temperature and firmer when cold. Resin that stays rock-hard or oily in warmth is suspicious.
- Smell. A mild earthy, slightly smoky smell is typical. Sweet, chemical or burnt smells are not.
- Taste. It is naturally bitter and earthy. Anything sweet may have been blended with sugar, molasses or similar fillers.
- Does not burn like sugar. Adulterants such as caramelised sugars behave differently on heat from a mineral-organic resin.
Why home checks are not enough
Each of these checks can be passed by a skilled counterfeit, and a genuine product can fail one by being processed differently. More importantly, none of them tells you the thing that matters most for safety: whether the resin contains heavy metals. Only a laboratory can tell you that.
How to read a shilajit lab report
- Lab identity. Is the laboratory named and independently accredited, not the brand itself?
- Batch number. Does the report match the batch on your jar, or is it a generic one-off certificate?
- Heavy metals. Look for lead, arsenic, cadmium and mercury, each reported as a measured value against a limit, not simply "passed".
- Fulvic acid. A stated percentage and the method used to measure it.
- Microbiology. Total plate count, yeast and mould, and absence of pathogens.
What we publish
Every Montavita batch is verified by an EU-accredited laboratory in Belgium before it is released, and the results are on our lab testing page. That is the standard we think every shilajit brand should meet. If a brand cannot show you batch-level results, treat that as your answer.
