OG-1 shilajit resin is collected in the Karakoram range and purified over six months using only cold spring water, then sun-dried without heat. Some suppliers use heat to shorten the process to around three months; we don't. Our independent laboratory reports are published in full on our Lab Reports page, so you can check them before you buy.

Retail, wholesale and manufacturing

OG-1 (formerly Shilajit Global) is based in London and operated by Omar Guevara Ltd, a UK-registered company. We have our own office, team and staff in the source country, which lets us collect shilajit directly from the Himalayan and Karakoram ranges, home to K2.
