Makes a big difference in circulation. 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.

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.

Well my friends. I had heard good things about L-Arginine with regards to, ya know, stiffening things up a bit. Of course, I was more than a bit skeptical. I am 45 years old, and Herbie still loves to get up and dance, but as of late he seems to not want to dance as long as I do. He would bust out of the gate like Secretariat, but didn't want to keep that stride for the entire race. I tried to reason with him and I took a firm stance. He, however, took a slightly softer stance. We have debated and sometimes, if the mood is right, Herbie would comply for a bit longer. Normally he gets the job done, and my girlfriend was fine with everything. NOT ME. I wanted 25 year old Herbie like he was glistening out of the showroom. I wanted him to run a Daytona 500, not a 10 lap coast which slowly came down to idle. I have Viagra which I will use on occasion if I really wanna go for hours and walk around with a baseball bat that can be used during a home run derby. But I do not like the headaches, flush face, and stuffed up nose that would accompany it. ENTER THIS CRAZY STUFF. I have been taking 2 tablets a day for a week. One in the morning, one before bed. No joke, by day 3 Herbie was acting like he just had a tune up, lube job (haha), and a new set of tires. This is not a testimonial written by the company or some employee. I am just like you. This is legit. I have had more sex this week with my girlfriend than in recent memory. I no longer worry about when he will decide to slow down and pull off to the shoulder leaving me looking like a lost puppy hoping for a tow. He just wants to keep going and I feel like I took Viagra, but without the side effects! Yesterday? We went at it 3 times. All 3 times, completed the race the way he started. These aren't sprints. We are talking 45+ minute cruises down the interstate. Needless to say, I am ecstatic with the product and highly recommend it to any others who have a little buddy that seems to want to putter out after a quick drive around the block. TRY THIS STUFF. You and your Herbie will thank me. **Disclaimer- Could this all be in my head? Placebo effect? Maybe? But I honestly don't think so. My girlfriend doesn't think so. I know what Viagra feels like, and this is similar. At least for me. Good luck!

This is some good stuff! I have stents and I originally bought this for better blood flow and lower my blood pressure. It does all of that, and also some bonus effects that will maybe make your wife happy also. I take one in the morning and one at lunch. Makes everything, and I mean everything, work much better. UPDATE: I have since had a quad by pass, and with using this stuff I am completely off of any blood pressure meds. And, everything works just fine.

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 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.

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

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.

Guys these help blood flow everywhere if you know what I mean.
