Lab Reports & Certification

OG-1 (formerly Shilajit Global) is a trading name of Omar Guevara Ltd, company number 05183250, registered in England and Wales. Our Himalayan shilajit is collected in the Karakoram range, purified in cold spring water over six months, sun-dried without heat, and tested by an independent laboratory. The lab reports below are published in full.

Independent testing is the only meaningful answer to the question every shilajit buyer asks: is this real, and is it safe? Below are the actual documents — not summaries of them. Open, read, and check them against anything else you are considering.

How to read a lab report

Lab reports are written for chemists, not customers. If the terminology is unfamiliar, we have published a plain-English guide to what the parameters mean and which numbers actually matter when comparing suppliers.

Fulvic acid
The compound group most commonly used to characterise shilajit. Concentration varies with source altitude and processing method, and is the figure most often overstated in this category.
Heavy metals
Lead, arsenic, mercury and cadmium. Because shilajit is taken from rock, screening for these is the single most important safety test, and the one to check first on any supplier's report.
Ash content
The inorganic residue remaining after combustion. High ash content can indicate mineral soil or filler content rather than pure resin.
Moisture content
Water retained in the resin. This is what makes our OG-1 line softer to handle and the Salahuddin line firmer, and it affects concentration per gram.
