Creatine
ISSN position stand pre-workout stack: creatine raises ATP capacity, beta-alanine (→carnosine) buffers lactic H+. Combination > either alone; best for HIIT + resistance. Avoid co-ingesting with high-dose caffeine in the same window.
L-Citrulline
Pre-workout pair: citrulline → NO → blood flow ↑; beta-alanine → carnosine → H+ buffering. Different mechanisms, same window — combined effect strongest in multi-joint high-rep resistance.

Beta-alanine is a non-protein amino acid. Unlike leucine, it doesn't enter muscle protein directly; unlike creatine, it doesn't directly refill .

What it really does is more indirect: once inside muscle, it combines with histidine to form carnosine.

Carnosine = beta-alanine + histidine

The key point: histidine is relatively abundant in muscle, so beta-alanine is the rate-limiting raw material for carnosine synthesis. Supplementing beta-alanine isn't really 'supplementing an amino acid' — it's adding an intracellular acid-buffer reservoir to your muscle.
