I found this when I started researching alternatives to Pergolide prescription for my 27 year old TB mare that had been diagnosed via blood test by the vet. Her top line and rear end had muscle wasting, she had not shed well, her hoof sole had become painfully soft and she was very lethargic. I started her on this supplement in July and she showing great improvement. It has been 5 months on this and she is now trail riding, has muscle tone coming back and is full of energy like she used to be. Thank you for such a great product, I feel this stuff has added years to her having a full and happy life!update 4/20/2015It has been 9 months on this supplement and I am happy to say my now 28 year old is doing better than ever. Her winter coat has shed out beautifully for the first time in years! She is alert and back to the horse I remember when she was young. She has maintained her top line even with having the winter off and has stayed sound throughout the last few months with no signs of stiffness or sore feet, she even has a solid frog which we struggled with in the past. This is the miracle she needed and I have recommended it to many of my customers. I love this stuff and would give it 100 stars if I could.
