For now, Nothing is happening. But I think that I feel a little bit sleepy after taking with meal for three days but I only took one instead of two. The packaging was perfect and shipping was fast. The capsules look fresh and no smelling and no awful taste. So giving 5 stars for now.

I really do like this product, I notice the clean energy that I get. I haven't been working out with this product yet since my exhaustion has been lessening at lot. I'm trying to use a combination of supplements with this product to help with exhaustion and depletion of nutrients.

Exellent product..!!! But why it is not all the time available?? This is what you meed to take if you are looking at L-arginine benefits..!!

My husband uses this for fitness and wellbeing, I'm not really sure what it does but he says its good for oxygenating the blood and improving heart and lung health. He loves the quality, price, and taste.

This is our first time trying iHerb — we found it online because it was the cheapest place to order our supplements. The shipping was super quick and wasn’t delayed as most of our Amazon orders have been lately.

I like to workout in the evenings after work, but am often low on energy and have to rely on some source of energy before I go to the gym. However, when I take typical preworkouts (powder) I get too anxious, feel strong "ants," and get an upset stomach. I was recommended L-arginine by a friend who takes it in place of preworkout. I tried out the substitution as well and fell in love with the energy it gave me, without any of the discomfort of typical preworkout powder. I take this supplement with my afternoon snack and have the perfect amount of energy by the time I go to the gym!

I love to work out. With weights. I also work out with bands. Sometimes with heavy items like exercise balls, which I guess are like weights. For me, its the blood that really keeps my muscles going and I need it. Lots of it. In fact, I want all my blood as strong as possible. I like L-Arginine because it gets more blood to where I need it. The Weights. I suggest you get on this ASAP

This really has helped my workout routine! I am noticing better gains and have more energy throughout my workouts. Couldn’t recommend this product more.

I was recommended these by a friend and it does the job. It's the real deal. Noticed I was able to perform better at the gym much longer. Well worth and will buy again.

Excellent product for this who work out a lot and not taking any coffee or prework outs! I’m always open for healthy options and this works just great for me.
