BioTechUSA Beta-Alanine Powder 300g

The burn that ends a set is acidity building up faster than the muscle can buffer it. Carnosine is the buffer, and beta-alanine is the amino acid that limits how much carnosine your muscles can hold - which is the whole reason to supplement it.

Raising muscle carnosine pushes that burn further out, so the sets that fail at twelve reps start failing at fourteen. It is most useful in the two to four minute range - CrossFit, combat sports, rowing, high-rep work - rather than in a heavy triple. BioTechUSA sell it as 100% pure beta-alanine with no fillers, sugar or fat, which lets you dose it where you want rather than accepting whatever a pre-workout decided. Expect a harmless tingle on the skin; it is the ingredient working, not a problem.

The 300G tub is unflavoured, so it stacks into a pre-workout or juice without changing the taste.
