QuadPRO EXT 2LB was formulated to provide long lasting positive nitrogen retention within the blood stream to enhance muscle repair, recovery and growth.
It utilizes both fast digestion proteins such as collagen peptides which begin releasing nitrogen within minutes of ingestion and milk and casein proteins which slowly digest and assimilate for up to 6 hours.
This EXTENDS your muscle building window with active nitrogen to build and repair for several hours after ingestion.
Additionally, an efficacious dose of Astragin® has been included in the formula. Astragin® is a nutrient that has been clinically proven to enhance protein and amino acid uptake by up to 30%
