HMB is a focused, single-ingredient formula for people who want extra muscle support when training hard, dieting, or pushing recovery. Each serving delivers 3,000 mg of myHMB®, a clinically studied form of β-hydroxy β-methylbutyrate chosen to help support muscle retention, reduce exercise-related muscle breakdown, and improve recovery from tough training. That makes HMB especially useful during calorie deficits, high-volume blocks, or periods when preserving lean mass matters as much as performance.
Instead of burying the ingredient in a blend, Legion keeps the formula straightforward with one fully disclosed active, a clinically relevant dose, and no unnecessary fillers, food dyes, or hidden extras. Each bottle provides 30 servings in easy-to-take capsules and is third-party lab tested for purity and potency, giving you a clean, transparent HMB supplement built for serious training.

Overall rating: 4.8208957 / 5 from 67 reviews.
HMB β-Hydroxy β-Methylbutyrate is a high-quality supplement supported by 15 peer-reviewed studies, praised for reducing muscle loss, enhancing recovery, and improving muscle strength. Customers appreciate its effective dosage, minimal additional ingredients, and noticeable reduction in soreness after workouts.

"Great product! My left forearm was extremly sore for a while until I strated taking HMB. Now it's part of my monthly supplements for sure."
— Daynel A. (5/5)
"Helps protect my gains when I'm in a deficit, helps bolster them when I'm at maintenance. No side effects. I don't exercise whilst fasted normally, but regardless, I find HMB has helped quite a bit. My pick for the most essential supplement outside of creatine."
— Nico (5/5)
"Recently started taking Legion HMB to assist with replacing fat with lean muscle. Also for the purpose of assistance in recovery from 2-3 hr workouts. Taking it prior to workouts in addition to Legion Creatine which I really enjoy the taste of in my hydration. Feel that it is helping as I am in my 60's and need all the help I can get to achieve my fitness goals. Seeing some initial progress and looking forward to continued transformation of my physique."

"I’ve been using Legion since 2017, and the products always deliver. Legion HMB is no exception. I almost always train fasted or with little food, so the muscle preservation aspect is vital. For many years, I used Forge for the HMB, but my body doesn’t handle yohimbine and it made it difficult to bulk. Legion HMB is a stellar replacement to get the muscle retention benefit without any undue side effects. I would absolutely recommend it to anyone interested who is cutting or trains fasted."

"So far what I have noticed recovery is a bit faster . I don’t feel as sore after a leg day which are my hardest days . Capsules are flavorless no after taste . On my last weigh in I did loose some body fat and muscle stayed the same . During a cut I’ll take that . Already ordered more ."
