This bottle is crazy. I take it inconsistently throughout the day, but if you take it at bedtime, look out….. IDK how long it will take you to see results but for me it is literally now a discreet recognition where I’m like “dang it, my brain is totally sharp and awake now, it’s just my body that’s feeling drained”
Such an awesome, game changing supplement.

It definitely gave me a boost in energy. Even more so than the meth.

Makes a big difference in circulation. Taking 7,000+mg a day and my erections became as hard as concrete and my veins popped… I stayed hard for along time and gave my lady friend some intense orgasms in bed, every time. This stuff works.

If you’re working out and not taking this you’re missing out on a lot of natural gains!

L-Arginine is a precursor of nitric oxide which helps dilate blood vessels. The tablet size may be a little larger than what some people mught be comfortable with but I find them okay. No after taste. Since supplements are not approved by the FDA, it is always best to go with an older and reputable manufacturer like NOW.

It is not a capsule, it’s a tab, which may turn some off. Having said that, one tab a day and it does the job for myself. I do a bit of swimming and use the wet area services, on an almost daily basis. It allows me to sweat at a very rapid and profuse way both in the Sauna and Steam Room, which does wonders. It helps me keep trimmed and toned and my overall sense of well being.
Reg –
Amazing product. Well, not sure if it’s the brand or just how L-Arginine works, but I feel more pumped in the gym. Also, at over 50 this has also helped me out in the bedroom…I kid you not. Lol.

I bought this in an attempt to perk a sagging libido. Did it work, you ask? Better than I thought possible. I’m over 50, and am finding that nature is cruel. After taking this stuff for about 2 weeks, I started waking up, let’s say, “in the mood”, like when I was in my 20s. I’ve also noticed that I’ve toned up physically, without doing any extra exercise. Will it work for you? I can’t say. It certainly did for me.

So far the only think o have notice is makes you horny like a young boy. It gives you more alertness and sure helps blood flow.
Antonio Gutierrez –
I use this for some sick pumps in the gym. It gets the blood flow going without all the caffeine. I hate preworkout so this always helps me before a workout and not to be inappropriate but the vasucularity also helps in the bedroom. I always take it before I know I’m getting laid and it helps with stamina
Michael –
The double strength dosage works for me. More specifically, I see improvement in blood flow and stamina. Be careful not to overdose (especially on an empty stomach) as it may increase bowel movements.
Michael Myers –
I bought these since I wanted a little extra help sometimes. These work pretty well at improving erection and bloodflow. I also feel like I have a bit more energy after taking them.

I use 2 g of this with 100 mg DHEA, 50 mg pycnogenol and 2 tabs of citrulline for ED. It has restored satisfaction to my life. You can’t beat the price on this and I have no problems taking it or keeping it down.
Doctor –
I monitor my blood pressure every day and L-Arginine has helped lower my blood pressure. It’s good to have after a big meal. The larger dose (1000mg) makes more sense than the 300mg dose. Taking it once or twice daily.

This L-Arginine supplement (along with beet root and pomegranate – I also take C0q-10 -has reduced my blood pressure by 30+ points which is VERY significant. Like many women, after menopause my blood pressure rose astronomically. I’m 72 and this is the lowest it’s been in years (it now reads between 137/71 to 117/60 instead of 166/90! (I do several readings daily and keep a journal). Yes the tablets are huge BUT because I also have to take L-Lysine for a number of years now and the tablet is the same size, I began first by using a mortar and pestle to grind the tablet down, NOW I just use a small prescription-sized bottle, add a small amount of hot water at night, plop the L-Lysine, the L-Arginine and my vit. c tablets in, let it dissolve over night and in the morning I throw the solution of all three to the back of my mouth, swallow and then immediately drink cold water behind it. Trust me, this works, just don’t swirl it around like a beverage because it’s bitter!

Frankly, L-Arginine didn’t do what others say it did for me. I did have a great result with a medical problem I have had for a longtime. I have had stubborn toenail fungus on my large toe for over 10 years. While taking this product I notice good nail was pushing out the bad nail. I thought it would never grow all the way out before getting the fungus like the rest of the nail, but it did grow all the way out. I have had the nail laser treated twice 5 years ago, but it had no effect. Somehow L-Arginine got rid of my nail fungus. I have been fungus free for months now. I’m so happy it’s gone.

Trying to gain lean muscles and taking this supplement along with L-Carnitine, and other protein shakes. No major difference after I started taking this since I’m already taking a wide range of other supplements. However, I do feel a warmth that goes through the body and head after taking 30 mins and when you begin exercising. So there is definitely an element of blood circulation improvement for those that are seeking cardiovascular health. On the flip side, if you’re looking for muscle gaining, the supplement effects might be too minimal.

needs. (What were you expecting?) Yes, what you’ve read about, online, is true: This stuff does, in fact, help release nitrous oxide from the blood, thus helping fill the old corpus cav. Highly recommended.
Update: I guess I left out, above, that these pulls are the size of horse tranquilizers: Really BIG. After taking them for a while, I find that they are getting harder to choke down. I will be looking for a smaller alternative. I’ll update, in here, if I find one.

It works. I was sceptical, but decided to try it. I started using 1 tablet a day, on a empty stomach, for the first week.
Then increased it to two, of which one in the morning and one at evening time . I didn’t take anything else, nothing.
From the end of the second week I started noticing a difference: mainly the ED symptoms I had before was gone. I’m 51 years old. Maybe it’s all in the mind, but it doesn’t matter since it’s working.

L-Arginine increases uric acid in the blood and kidneys. The first time I took this (1000 mg/day), 3 weeks later I had a major gout attack in my knee. The second I took it (8 months later), I developed a uric acid kidney stone, also 3 weeks later. I don’t think there is anything wrong with the product itself, but the dosage is definitely too high for my system even when I drank a gallon of water over the course of a day. I will never take it again. Use this with caution, and drink *lots* of water.
Jacob Vaughn –
The only thing thing that I could nitpick about is exactly the thing I like about them. 2 doses of 2 huge pills a day can be a challenge to some but I prefer to just get it over with. My previous l-arginine supplement called for me to take 1 pill 6 time daily and there isnt that many times a day that I’ve got an empty stomach lol
Roy L. Reed III –
Excellent product! Definitely longer workouts in the gym. And all those reviews weren’t lying. My wife loves the fact that I started taking these as well!!!!
Ken W –
Increased energy level. Best value for this substance. Libido improved as well.
Michael Ganzermiller –
This stuff really works well
I have been taking it for about a week now and can see a major improvement. I’m 67 and I have a 45 year old girlfriend and she can’t keep up. Twice a day 3 times a week sometimes more. Yahoo
James Lerner –
I’m taking 1000MG 3X a day. I’ve done this for two weeks. A day ago I upped it to 2000MG 3X a day just to experiment. Taking 1000MG 3X a day my neuropathy feels 75% or more better. My blood pressure is lower. I have more energy and less stress and anxiety. I had tried everything. I was starting to think all natural remedies were snake oil. I had never tried L-Arginine. I ordered 2 bottles. I just ordered 2 more bottles because it’s a good deal. 1000MG per tablet is rare to find. The NOW brand is good. I waited a few weeks before I did this review. After a day or two I was already noticing improvement.
