Home / Certificate
Every batch is tested before it ships, and its certificate is published on this page in full. That is the entire system, and it is the one thing almost nobody else in South Africa will show you.

Shilajit comes out of mountain rock, and raw rock carries lead, arsenic, mercury and cadmium. Purification is meant to remove them. Only a laboratory test proves that it did, which is why "purified" on a label means nothing without the paper behind it.
Genuine raw resin typically measures between 15 and 35 per cent depending on the assay used. Numbers far above that usually describe standardised extracts rather than raw resin, or come from a method the seller will not name. Ours reads 35g/100g by titration, and we print the method next to it.
Real purified resin dissolves almost completely in warm water. This batch measured 97.2%. Grit that will not dissolve is a classic sign of filler or an adulterated product, and it is something you can check yourself at your own kitchen table.
Certificates stay published permanently as jars sell through. Email care@purepharm.co.za with roughly when you ordered and we'll send that batch's report the same day.
