Of course, I was a little skeptical at first, but after feeding this to my pups for about a month, and my pups are 14, 13 and 10, I really noticed a difference after about 2 weeks. I am amazed at how they are playing and how much energy they have now just like when they were much younger. My 14-year-old runs now and he has not run in at least a couple of years. They are excited to eat it. They love it. As soon as I get home from work they're like, where is my dinner? I am very happy I took it.
Bottom Line: Yes, I would recommend this to a friend
