Product Overview

Build Muscle and Recover Faster

Muscles are your horse’s motor, and the right fuel can help him reach his full potential for speed, endurance, relaxation, and overall body condition. With research-proven ingredients for muscle development and recovery, Muscle EQ™ Powder was specially designed to deliver maximum support for the equine athlete before, during, and after exercise.  

Horses cannot properly maintain or build muscle if their amino acid intake is too low.  This comprehensive powdered formula delivers a powerful boost of leucine, lysine, and methionine – essential amino acids that are not produced by the body and must be obtained through diet – to develop and preserve lean muscle bulk. It also contains trimethyl glycine (also known as TMG or betaine), an ingredient shown to enhance exercise tolerance, improve hydration, and reduce lactic acid buildup for longer training sessions, as well as the amino acid beta-alanine for optimal muscle function and recovery. Acetyl l-carnitine provides potent antioxidant support while also helping to activate the enzyme pathways that bring glucose out of storage, ensuring your horse’s muscles have sufficient energy to perform and relax during and after rides.  

  • Potent amino acids promote lean muscle development and enhance definition.
  • TMG, Beta-alanine, and Acetyl L-Carnitine encourage optimal muscle function and recovery.
  • Comprehensive support for the equine athlete before, after and during exercise.
Made in the USA.

Muscle EQ™ Powder is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from Buying again bc it works fast I like this product bc it works. My horse likes it. I would have given it 5 stars except I wish it didn't have maltodextrin in it which is a sugar and my horse is metabolic. But I am going to keep using it bc the muscle development is rapid and I have tried many others things that were less rewarding.

Rated 5 out of 5 by from Unexpected Performance, Impressive Results I'm impressed. My horse, a senior mustang with PPID, has been using Muscle EQ for three months now. Her forearm muscle mass has increased by more than 1.5 inches. She has a natural exuberance that I haven't seen for several years, including her interest in trotting when being hand-walked. I started this supplement because my mare has a chronic stifle injury. I hoped Muscle EQ would help strengthen muscles in the stifle area. Her unprompted interest in trotting tells me she trusts those muscles to handle her weight and allow her to move out. I'm very happy with Muscle EQ.
