What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

The formula contains beta-alanine and betaine, which have moderate to strong evidence for supporting muscular endurance and power output. Arginine alpha-ketoglutarate, taurine, and tyrosine are included to support blood flow and cognitive focus, though evidence for their acute ergogenic effects is more limited. These ingredients are generally recognized as safe at standard dosages.
