“This product was prescribed by my Vet. My mini horse has EMS, and Thyro-L has corrected the issue. It worked within 24 hours and now I have a happy , healthy , active mini horse. Would recommend this product to anyone who has the same issue with their horse. Allivet is a very reliable company, shipping is done in very good packaging, delivery is prompt. Would recommend Allivet to everyone who needs pet products. Thank you, Allivet!”
