I work with UFC fighters Anthony Pettis, Chris Holdsworth, Carla Esparza and many others. I recently brought a Muay Thai fighter to Bali Her name is Tiffany Van Soest and she is one of the top female fighters in the world. It was super hot and humid. We could not keep her Hydrated. After the 1st day I had remembered that I had brought 2 packs with us. She took 1 before training and felt great. Plus 1 after. We also used them after surfing. They saved us from cramping and feeling dehydrated many times. Please send more and I will use them with All my client’s.
