PURE PROTEIN GUARANTEE

PURE PROTEIN GUARANTEE: Siren Labs' ISOLATE PROTEIN is formulated with only pure sources of protein and no amino spiking. BIOAVAILABILITY: The protein sources found in this product rank among the highest on the biological value scale.

Muscle* Amino acids are the fundamental building blocks of muscular development. Although your body needs fat and carbohydrates to function, you simply cannot build muscle without protein. Intense physical activity causes micro tears within the muscle and depletes internal protein stores. Supplementation helps to replenish these stores allowing for muscle repair and growth.*
