Why people use it
Used with the goal of sustaining hard efforts and delaying fatigue during high-intensity training.
These are common goals and marketing uses. The evidence section below explains what research supports.
What does the evidence tell us?
Research suggests benefits for some repeated or sustained high-intensity efforts, but results vary with the activity. It works through changes in muscle carnosine, rather than an immediate stimulant effect.
What should I know before using it?
Temporary tingling can occur. Tingling is not a measure of how effective a workout supplement is.
