I discovered Shilajit about a year ago at a tradeshow on dietary supplements. I had a sample during the day and felt full of energy all day. In the morning I woke up more refreshed than usual. I tried Shilajit from many vendors and never got back that same experience until I found the Shilajit from Himalayan Healing. Since then I no longer use the snooze button in the morning, i wake up full of energy. I highly recommend this product.
