Both are UK-facing shilajit brands. The separating factors are whether the resin's laboratory results are published per batch and whether the batch on your jar can be checked independently.
Ayor Health sells pure Himalayan shilajit resin in the UK from £34.99 (20g), £49.99 (30g) and £69.99 (50g). Every batch is independently tested by Eurofins UK and the reports are published in full at /lab-results.
