Frequently Asked Questions
How do I use HMB?
Take 1 serving (4 capsules) about 15 minutes before fasted training. HMB is most effective when taken before workouts that occur in a fasted state, because that's when muscle protein breakdown is highest.
What makes myHMB® different from other HMB?
Many HMB supplements use generic, underdosed β-Hydroxy β-Methylbutyrate. myHMB® is a patented, pharmaceutical-grade form with over 50 peer-reviewed studies supporting its safety and efficacy — the most-studied HMB on the market.
Do I need HMB on rest days?
Not really. HMB is most effective before fasted training when there's exercise-induced muscle breakdown to prevent. On rest days it offers minimal benefit, though you can take it if you're cutting or want daily consistency.
Can I take HMB with creatine or protein?
Yes. HMB works well alongside creatine, whey protein, and other supplements. If you want both HMB and creatine in one product, Legion also offers Creatine + HMB.
Is 3,000 mg the right dose?
Yes. 3 g per day is the standard clinically effective dose. Studies have tested up to 6 g/day safely, but there's diminishing returns above 3 g. For extended cuts or bedrest, some research suggests splitting 3 g into three doses throughout the day.
