ALT Pre-Workout is built for athletes who want a complete pre-workout formula without sucralose or artificial dyes. The formula delivers 300mg caffeine alongside 125mg theacrine (TeaCrine®) for extended energy without added tolerance build-up — a combination that delivers more sustained performance than caffeine alone. On the pump and performance side: 8g citrulline, 3.2g CarnoSyn® beta-alanine, 1.5g betaine, 350mg N-Acetyl-L-Tyrosine for cognitive focus under stress, and 2g taurine. Coconut water rounds out the electrolyte support. Forty servings, six flavours, 454g tub.

Not ideal for: Caffeine-sensitive individuals or beginners — 300mg caffeine is a high-stim dose. Note that beta-alanine causes a temporary tingling sensation in most users at this dose. Avoid within 6 hours of bedtime.
