I will try to answer these questions the best that I can. I am not a scientist, I am a farmer.
Diane- They do have a human form of the product that they market as well. I have been told the exact formulation is somewhat species specific though, so don't drink the canine form yourself.
Pearse- Although I have a brother named Jim, my name is Jeff. I do not personally know of any independent peer reviewed science. As I said I am not a scientist, I do have an Animal Science degree but I know quite a bit more about genetics and reproduction than physiology. All that I know for sure is that the product has produced in my dogs as advertised, and that I have spoken to the owner of a racing greyhound kennel who buys the stuff by the gallon. He has seen a significant decrease in race times, increased winning percentage for his kennel, and a significant decrease in dogs tieing up and not being able to urinate after they run. They have experimented with the product quite a bit. At first they put the product in their second tier dogs because they were skeptical about it. When their second tier dogs started beating their top tier dogs their skepticism ended, and they put the product in their top tier dogs.
Sheeptramp- If you want a response ask an intelligent question like Pearse did and sign your name to it.
The only thing I know for sure is that my unscientific experience with this product has been wholly positive. I do not understand how it works completely, but I believe my observations are pretty fair. I hope people keep an open mind an some folks try the product. I would love to hear the results of a blind study as Pearse described. Thanks for your comments and interest.
