I bought a packet first and then saved it. One day I had a long ride and was really tired, so I mixed the packet with water and drank it. My energy returned and as it said, either eat a meal in one hour after drinking (which I did) or have another packet. In talking with fellow cyclists, I found some were putting this product in their water bottle, so now I do that. In my waterbottle I put half pure juice, half water and almost a full scoop of recoverite. As most rides have a lot of elevation gain, this makes the difference. I have a full scoop in water when I get home and the rest of the day is not lost trying to recover. I bought the strawberry.
