I drink it while I sleep

The capsules may be a little large. To be honest, I didn't notice much difference when I took them before exercise, but when I took them before going to sleep, I felt like I was able to recover from fatigue at the usual time.

I've been taking it for a week now, and the product seems to be good. I've had a good experience comparing it with other brands. I'll add a review if I change my mind.

I started taking a nitric oxide boosting supplement and noticed the difference in my workouts almost immediately. I have more stamina, better muscle pumps, and I feel more energetic. I've also read that it helps improve circulation, so I continue taking it with confidence.

Very very good!!!
Verified Purchase
The advanced L-Arginine complex (1,500 mg total: free base, HCL, AKG) + L-Citrulline (750 mg total: free form, malate) in 3 capsules daily is a superior formula for maximum nitric oxide boost, intense muscle pumps and optimized blood flow. After 10 days of pre-workout use, I noticed firmer erections, explosive endurance and visible vasodilation, without bloating or side effects. Strong, pure and effective dosage – perfect for active men who want serious results, I recommend 100%!
