Pump & Endurance Duo
The two ingredients behind a great pump and longer sets, paired up. Citrulline Malate delivers 5g per scoop to support nitric oxide production, blood flow and pumps. Beta-Alanine supports muscle carnosine levels to help delay fatigue, so you can push through more reps and rounds. Both are unflavored, single-ingredient powders that mix into water or any drink. No proprietary blends, no fillers.*
