4Plus PumpStack™ L-Arginine + L-Citrulline | 120 Capsules

PRIMARY USE: Combined L-arginine and L-citrulline support for nitric-oxide-focused training nutrition.

Arginine is a direct nitric-oxide precursor, while citrulline can help increase circulating arginine availability. Combining both provides a convenient amino-acid option for pump and performance-focused workouts.

WHY USE IT

• Two complementary amino acids in one formula
• Convenient capsule format
• Fits pre-workout and performance routines

VS. NOT USING IT: You can train effectively without nitric-oxide supplements. They are an accessory to—not a replacement for—programming, hydration, carbohydrates and recovery.

FOR YOUR LOOK: A training pump can temporarily make muscles look fuller, but it does not equal new muscle tissue or fat loss.

SMART USE: Follow the label. Consult a healthcare professional if you use blood-pressure medication, nitrates, erectile-dysfunction medication, or have cardiovascular or other medical conditions.
