About this item

• NOW WITH NITROSIGINE FOR EVEN GREATER PUMPS!

• Nitrosigine has scientifically validated that benefits last up to 6 hours after dosing.
  
  
• 1-SCOOP SERVING: NITRAFLEX is so potent, only 1 scoop (1 serving) is necessary. Do not exceed 1 scoop in a single 24-hour period. Do not take NITRAFLEX within 5 hours of bedtime.
