Support muscle development and function in your performance horse with the Finish Line Performance Builder Horse Supplement. Carefully developed over a three-year period, this formula is not a steroid and is safe for horses who are weanlings and older. This product contains only ingredients that support healthy muscle development in the horse, such as spinach, pea protein and L-leucine, so you can feed it with confidence. It wonâ€™t change your horseâ€™s temperament, but you can expect to see changes in your horseâ€™s physical appearance in just two to four weeks. This liquid supplement makes for easy grain top dressing and its butterscotch flavor appeals to even the picky eater. Whether you want a sales prospect to look his best or are preparing your horse for the show ring, this supplement can support the conditioning work that youâ€™re already doing.
