🧬 Why This Data Matters

⚡

Protein Percentage

True isolates should be 90%+ protein by weight. Lower percentages mean more filler and less value per serving.

💰

Leucine Content

2.5g+ leucine per serving triggers optimal muscle protein synthesis. This is the most important metric for muscle building.

🎯

BCAA Ratios

Complete BCAA profiles (leucine + isoleucine + valine) provide better muscle recovery than leucine alone.
