I've always generally thought recover specific products were mostly smoke and mirrors but it got my attention when I saw that Tailwind was offering a recovery drink. With the huge success I've had with the endurance fuel I decided it was worth trying out the REBUILD. This really does make a noticable difference in how quickly I recover and feel back to normal after my long runs. It also seems like it's much sooner that I can start replenishing my body with regular food when I've taken REBUILD compared to not. I'm hooked and just placed my third order!
