Source: ISSN Position Stand: Beta-Alanine (Trexler 2015) — 3.2–6.4 g/day for 2–4+ weeks raises muscle carnosine and endurance.
An amino acid that builds up carnosine in muscle, buffering the acid that makes you fatigue.
Raises muscle carnosine, which soaks up hydrogen ions during hard efforts.
Daily loading raises muscle carnosine and improves performance most in efforts lasting 1–4 minutes; benefit is from accumulated carnosine, not any single dose.

Beta-alanine's ergogenic effect is greatest in capacity tests lasting 30 s to 10 min; negligible for very short or very long efforts.

Bottom line: Solid evidence for a small edge in high-intensity efforts of 1–4 minutes — but only after weeks of daily loading. A single scoop in a pre-workout does nothing acutely; the tingle is not the benefit.
Harmless tingling (paresthesia) on the skin — split the dose to reduce it. That's the only notable effect.
