Short answer: The three amino acids sit inside one 500 mg proprietary blend, so the combined total is published but the individual split is not — a direct, honest disclosure worth understanding.
Why "combined total" and "individual split" are two different things
Knowing the full blend weighs 500mg is meaningfully different from knowing how much L-Arginine HCl, AAKG, and L-Citrulline Malate each contribute individually.
Why the site names this as "the single biggest limitation"
Rather than softening this gap, the formula's own materials directly label it as the single biggest limitation — a genuinely candid admission worth appreciating.
💡 Worth knowing: only the individual ratio within the 500 mg blend is undisclosed — every ingredient itself is still named plainly.
