Beta-alanine increases intramuscular carnosine - the buffer that absorbs the hydrogen ions responsible for that 'burn' during high-intensity efforts. More buffer means more capacity before fatigue forces you to stop. Creatine is the most extensively studied ergogenic supplement in history, with decades of RCT evidence for sprint power, jump performance, and lean mass.
But here's the piece most performance stacks miss: connective tissue. Tendons, ligaments, and joint cartilage are the structural foundation that lets you produce force safely. 15g of collagen peptides taken 30-60 minutes before training - with vitamin C - significantly elevated collagen synthesis markers in tendon and ligament tissue. The timing matters because exercise-driven blood flow to connective tissue coincides with amino acid availability.
Precision Performance is built for the person who wants to train hard, recover fast, and protect the structures that make it all possible.
