STACK SUMMARY:
BENEFITS are modest and average only a few percent.
The FITTEST athletes respond least. Highly trained endurance athletes often see nitrate effects shrink toward zero, and a buffering ceiling is plausible for the others.
Recreational and moderately trained participants account for most of the positive signals.
What this means? The athletes most motivated to chase a final fraction of a percent are often the ones for whom the standard protocols deliver the least. The typical AG athlete stands to benefit more.
Side effects are the real adherence problem. Caffeine can heighten anxiety, Bicarbonate brings gut distress and Beta-alanine brings harmless skin tingling. None of which track well with how well the supplement works.
Timing follows the mechanism:
CAFFEINE 10-60mins prior to event.
NITRATE and BICARB are taken hours before.
CREATINE and BETA-ALANINE are multi-week loading projects that acute dosing cannot shortcut.
