Great value and as good for the quantity of pills in the tub and unlike the Jarrow one that is often out of stock it is always there.

Great Quality product. It works for me. It helps me with my work out. More energy sustained. I will keep buying it.

Great taste, it's good to eat before exercise. It improves my performance.

Why did I start with L-Arginine?: L-arginine may improve the sport performance by enhancing protein synthesis and tissue repair. l-arginine is also the precursor of nitric oxide used to increase muscular power, endurance and improvement in blood flow. The effects I have noticed are subtle. I will continue with just one tablet per day for a month and then discontinue use again for a while. The benefits are too low to use all the time. Also it might be better to take L-arginine together with other amino acids like Lysine.

I am half way consuming this supplement and I can say that it does something. I feel more energetic and active.

Only thing I don't like about this product is that it's really big and it leaves me an upset stomach sometimes.

This was recommended both after having a stroke and recently with an injury. It help provide better blood flow where it's needed for better recovery. It's made a big difference and appreciate this is a bilayer tablet. Having both sustained release and immediate release.

NO booster. it is a scientifically proven fact that NO enhancers such as arginine as well as nitrate-rich foods can interfere with the reproductive cycle of viruses such as SARS coronavirus.

This item actually does do what is pro-ported. It has helped me to overcome a large ulcer on my leg. And, I will continue to take it.

Taking as part of a structured regimen but so far can't tell if it made a difference
