Uckelele sold to smart pak, who is now smart equine, and is making this now. It is definitely not the same product it once was, it's darker in color and smells like rancid milk, and is significantly less palatable, my horses are dumping buckets and refusing to eat it. I have fed this for years with no issues but am swapping now.

I tried several products to help my older mare gain weight and muscle, including Cool Calories and Amplify. I had minimal results with both of these. This product did the job and I noticed a difference within a couple weeks of use. It has a pleasant smell and flavor so it should appeal even to picky eaters.

Purchased to help support an elderly gelding (34) and it’s a bit too soon to speak on its efficacy. However, it’s very palatable (picky eater approved) and not going to harm anything. So we’ll finish the container and see how things look after.

My two horses in their early 20s thrive with this supplement. I can always see when I run out from time to time because their top line suffers. Any product claiming top line improvements will have these 3 amino acids in it.
