Dont know how this product works yet, but I went through the entire bottle to make sure none of the pills were defective or lacking in powder and everything is perfect! Will update in the future how they work. Update: These worked for about 3 weeks for me and then abruptly stopped. Started taking more and it didn't last long. Now I don't really feel the effects at all? Shame these were helping me a LOT with energy. Won't be buying these again and will continue looking for something else.

I’ll start off by saying that I go through a lot of supplements but never have I encountered a quality issue like with this Nutricost product. I’m about half way through this bottle when I out comes this strange looking pill that looks like it was put together incorrectly. Upon closer inspection I notice that there is a hair in it... Yes, a hair... Absolutely disgusting and unacceptable. Upon inspecting more of the batch, I start finding some pills with black spots and containing unknown substances. The worst part is that I’ve already taken about half the bottle so who knows what I’ve been taking. Not only that, many of the capsules are cracked and broken, however this wasn't as concerning as the foreign objects in the pills. Anyhow, I would be extremely cautious if ...

For what it’s worth, these were bought from the seller eSupplements on Amazon.

I'm a 58 year old man. Have been experiencing some ED problems. I ordered this hoping that it helps. The first time that I took this, that night I woke up with a random erection, something that hasn't happened in a while. The next day at work after taking this for just a 2nd time, I am feeling a "fullness" in my penis and testicles. I do not expect this to completely solve my ED problems. But I think that taking this regularly is going to help me have a strong erection when I take my sildenafil citrate. I'll try to follow up this review after this weekend. My girlfriend will be surprised!

This is amino acid variety combining with L-Arginine in the ratio of 4 to 1 where 4 parts of L-Arginine and 1 part of L-Citrulline effectively promotes creation of Nitric Oxide (NO) inside our blood vessels. NO leads to dilation of arteries and reduction of blood pressure (BP). It helps me to fight my elevated BP (especially the systolic component - the higher number) and to reduce the usage of dangerous prescription drugs. However, there is the word of caution - combining this natural approach with high BP prescription drugs might cause sudden dizziness and lightheadedness due to the sudden drop of your BP.
I figured I’d to and save a few bucks and try this brand instead of my usual NOW brand. So far, not happy. I just opened the bottle to take a few and noticed my hands and fingers were coated with white powder. Either the manufacturer has a very messy area where these are filled and there’s loose powder all over the place or several of the capsules in the bottle have opened. Either possibility tells me that this brand has very poor quality control. I don’t want to risk putting anything in my body that’s made a facility that has such poor quality control. I should’ve stuck with my usual brand.If it’s from the manufacturers filling process then having product all over the place when filling capsules doesn’t sound like an FDA certified workspace to me.

I should’ve stuck with my usual brand.If it’s from the manufacturers filling process then having product all over the place when filling capsules doesn’t sound like an FDA certified workspace to me. If they are opening in the bottle it’s a sign that the manufacturer is rushing the filling/closing of each capsule because they’re hurrying to distribute and sell them. I personally don’t want any supplement that goes into my body to have been made at a facility that puts profits over quality control.Needless to say I won’t be buying anything from this brand. All of their products seems well below the price of everything else and it shows that they cut cost in areas that result in us receiving a less-than-acceptable quality product.My advice is to avoid this brand in general. They’re clearly focused on having the cheapest product on the market and their cost cutting methods to get that cheap price show.
I got this for my blood pressure and sadly not only did it not work for that it actually seemed to raise it slightly and that's not the only thing it raised. As you've probably seen from other reviews it works to make erections stronger and it does that very well !!!It works fast too. I don't have ED but this is still a game changer especially as we get older. Took about 20 minutes to kick in and you will notice a difference right away. Erections are harder and your penis might be thicker than usual, not some crazy amount but enough for her to notice. That reaction lasted a few hours so it will be a pleasant surprise for her to see you're ready to go again in 30 minutes. Yes it works that good!! The slightest stimulation and its go time!!
How do you measure such a supplement? Such evaluations are largely anecdotal. It's good enough to where I ordered it again and in a larger quantity. Price was reasonable. Prefer these capsules to tablets since they are easier to swallow and dissolve completely. Feel I get my money's worth instead of passing undigested portions of hard tablets. I use L-Citrulline now rather than L-Arginine since medical studies show it is far more effective in enhancing L-Arginine naturally - go figure...A good adjunct to this is Pycnogenol for boosting the body's nitric oxide as well as other benefits. Nitric oxide and increased blood flow are essential not only for circulatory issues but also those relating to cognative and erectile function. Helps in workouts too.Both ...

Most other supplements are nothing but hype and educated guesses.
I take many nutriceuticals daily. But when I have used this brand, I did not get the results I notice with other brands. They do not seem to have the same dosage that their label claims. Are they a cheap Chinese ripoff. I can't prove it, but it sure seems that way.
I used to take L-Citrulline of another brand. It was out of stock when I placed an recent order, so I decided to try Nutricost. As long as I research on the net, citrulline itself does not have any smell nor taste. I have been taking another brand citrulline and thought so too, but this Nutricost L-Citrulline has a strong smell of L-Arginine. Also, I started to experience stomach ache since I started taking Nutricost L-Citrulline. I usually don't have this symptom at all . On the other hand, L-Arginine is strong alkalinity, therefore some people may have stomach ache. Based on these observation, I suspect Nutricost L-Citrulline is not pure L-Citrulline. Another issue... some of the capsule were broken in the jar. All the capsules were powdery when I received the ... MoreI used to take L-Citrulline of another brand.

Ley me preface this by saying I work out 2 to 3 hours per day, 5 days per week. My resting pulse ranges from 52 to 63 bpm. The recommended dosage is two capsules. I took one of these on trial. Within 7 minutes my pulse was racing around 113. My blood pressure went from 130/80 to 235/150. I felt as if I were going to die. Immediately, I drove to the ER, where after a number of interventions over the next two hours, my BP was reduced to 140/ 90. Just my experience.
