Before your equine athlete starts racing or competing it must have the muscle mass to power its required workload. This work can includes sit and sprint as well as middle and long distance racing, jumping, dressage, eventing, endurance,  rodeo, polo, trekking, carts and games .

The Hanley Formula is the most powerful muscle building equine supplement available.

During hard training, racing and competing the large muscle groups which power the horse are broken down and damaged. The only way to build and repair these muscles is by providing your equine athletes the essential building blocks. The Hanley Formula contains all these building blocks.

By using The Hanley Formula your horse can produce and repair its own tendons, connective tissue (collagen) and ligaments.

  • The Hanley Formula is an amazing supplement. We use it with the young horses for weight gain and top line. It is great for building lean body mass. For our top eventers the amino acids are crucial to maintaining them at the top end of the sport, assisting with muscle recovery and metabolism.

  • I have been using The Hanley Formula as a supplement to my feed since September 2007 at which time Rangataua Ray and G Boss arrived to be trained , G Boss went on to win 1 race . Rangataua was broken in at the end of September and was continued with to Qualify and then race in his first prep for 9 starts - 3 wins 2 seconds and 3 thirds his only unplaced run being his first. Under normal circumstances this wouldn't be possible but at no stage has he had a problem in keeping condition on. I also use The Hanley Formula in with their feed even when spelling and I am very pleased with the results and the amount of muscle mass they tend to put on. I highly recommend this product as an easy to use supplement to add to feeds for both racing and spelling horses.

  • When I have a horse come into my barn they are instantly put on the Hanley Formula. Not only does their condition improve but their muscles develop stronger. It also very good for young foal and yearling development as it makes their growth grow evenly. I do not see my horses going up higher in the wither than the rear end. This product is a must for any person who has horses-be them racehorses or fun horses and I can highly recommend it to all. My feed shed is never without a 20kg bag in it.
