More muscle
I’ve been using this for the past 3 years with my 13 year old thoroughbred. It’s been particularly helpful in preventing him from losing condition in the winter. I start feeding it at the end of august and stop at the end of March as he has free access to grass over summer. He doesn’t get hot with it but has been able to consistently retain muscle 12 months of the year, which had never happened with other food products.
