I just got my fourth box from you. Always the best price and fast shipping. I feel better when I use the Myovite. I notice it when I let myself run out. I have more energy at the end of the day and I just feel better. I like the little tingles I get for the first 10 minutes after taking it. I was taking Animal Pak but this one has joint products and probiotics included so I tried it. I only take one pak per day normally and two on heavy workout days or after long rides. Good product.
