Awesome product; but tablets are HUMONGEOUS. Throat irritation from them being so huge & sister couldn't swallow them but I managed... Gotta suffer to get the results but this would be nicer in capsule form 1000mg (plastic caps)

It works. There is a definite improvement in performance. The only reason I dont give it a 10 is because of the size of these pills. They are HUGE and very difficult to swallow.

Decent product. I do feel like my workouts are better and more productive, but I think I can skip it next time.

really enjoy the size of the pills. i take 1 in morning, 1 after eating and 3 with my pre-workout - this works really great for me

I recommend L-arginine for anyone who wants an inexpensive boost while working out. I am on my 3rd cycle of this and it worked great when I first started and I'm slowly starting to see the results of this supplement pick back up. This really does help with blood flow.(All over your body) if you know what i mean. I find that this is a great supplement used in conjuction with Kre-alkalyn. I haven't used it with L-carnitine yet but I would imagine I would see phenomenal results. ***** your own tolerance to find you right dosage. I usually take 2 pills in the morning 2 pills in the afternon, and 2 pills before bed ( on off days). On workout days I take 2 in the morning, 2 about an hour before workout and 2 before bed. I drink it with cranberry juice.

Good price on L Arginine.

Seems to be effective when combined with L-Citrulline.

Nice product, works well, it gives me nice pumps and more power. I use to take 1000mg before my workouts.

Pill is a little big so it can be a pain to swallow sometimes and it tends to explode if left out of bottle in even the tiniest humidity. Will probably go with the 500mg next time.

Friends a little advice , great stuff! if u are looking for a great pump for your workout at a great price , go no further. Drink a double exspresso,take your creatine, take 3 tabs of Now L-arginine and you'll have your pre-workout supp for 1/2 the price , really good stuff great pumps !!!

Another Very effective product.. anyway I couldn't find the product I wanted (ON 100% Whey protein) which is very good! I would like also to than the company for the absolutely pro behavior to me, which I am overseas customer... (the delay of the delivery was as s result of our very bad customs, not the company) thank you again I try to have products only from you for me and my friends... (NIKOLAS - HELLAS)

I take one cap twice a day on workout days and one a day on off days. It gives me a great pump and makes me a lot more vascular during and after workouts. Take with lysine for best results. Highly recommended.

best pumps ive ever had, good when used in conjuction with a stimulant or another preworkout or good alone too, had the best pumps with this over any preworkout really cheap too

I would take 3 grams of this in the morning. It works great. I feel good. A must have which it is why this ingredient is in most pre-workout supplements.

This product made me have lots of dreams. And taking it for several weeks now have made me break out on my back and face. I do feel my muscles get really tight fast and seems as though I cannot lift as much or do as much reps. I am stopping usage for a few weeks to see what happens then will get back on it for a few weeks.

easy to swallow, helped my blood flow! Veins sticking out like crazy!

It is unclear the total effects of this product, but when mixing it with unsmoked or smoked yerba mate it had fantastic effects on my aggressiveness. a good stack is fresh yerba mate tea, L-arginine, Niacin 500mg, and Now B-50.

good for reduce high bp

IT HONESTLY DIDNT DO ANYTHING FOR ME.... NO PUMP, NO ENERGY BOOST OR ANYTHING

works very well, remember the more muscle you have the more you should take. I am 235lbs. so i take my pre workout drink and then 3 tablets 1/2 hour before lunch and 3 before supper,sometimes 2 more if i am up late before a snack then to bed.keeps me pumped all day.Good stuff.

Again a much higher grade compared to what you would get from the shelf at GNC. The quality is there and the benefits from oxygenating the blood is truly a benefit. However pay attention using NOX from the company based out of San Francisco uses the same ingredient as L-Arginine which is found here the only difference is that this costs around $20 and NOX is around $120 with the same dosages. NOX also states if the person is over 200lbs they need to take 5 tablets or 5,000mgs at breakfast and 5,000mgs at lunch which is insane. Your money your choice and most certainly your expense.

Have been taking this for about 3 weeks now and am seeing/feeling a difference. I'm feeling stronger than when I was not taking it, and harder. For the guys, I have also been feeling harder down south too. I recommend it. Only taking 1 a day, and 2 every 2 days.

These were poor quality, my tablets were breaking apart and would have a powdery mess in with all my other pills. I would say at least 50% of the pills broke apart for whatever reason, i would rather spend more money on a product that wouldn't do this.

I am taking this during my contest bulk/prep season to retain and repair hard earned muscle. I have not used it long enough to see results just yet
