BulkSupplements.com L-Arginine Powder - L-Arginine Base, Arginine 1000mg, Arginine Supplement - Nitric Oxide Powder, Nitrous Oxide Supplement - Gluten Free, 1000mg per Serving, 100g (3.5 oz)

Amazed by the rapid delivery! I was trying to order this L-Arginine powder during an Amazon outage that affected thousands of people yesterday afternoon (not a fault of the platform or Bulk Supplements, just a side effect of tumultuous events in the Middle East - for future readers reference, yesterday was 3/5/26, and America is currently at war with Iran). Later in the afternoon, the site was patched back up as I expected it would be, and I tried again - I had success in placing this order. However, I wasn't expecting to receive this for a few days or so - the earliest possible date listed was 3/7/26, a Saturday - but happily enough, it arrived in less than 24 hours after the order was accepted. This product is in very good condition, without a single noticeable mark, smeared ink on the package, or crimple in the thick bag it's sealed inside of. The powder itself is very fresh, clean in appearance (I have prior experience with this exact type of amino acid, a pure white powder is exactly what it should appear as), and the packaging is very descriptive with solid instructions for use provided in easy to understand measurements for a few different options to measure using any basic household kitchen items - anyone can understand and implement the correct mixing amounts without needing specialized tools. There are no clumps or evidence of water infiltration in the powder - even despite the humidity or spring weather with storms moving through the area having any affect on it, and it's clearly stamped with the expiration date in later 2030. There truly are no additives to the L-Arginine, which matches the product description and photos online, so no need to be concerned about fillers or ingredients that would otherwise dilute the strength. I only ordered 3.5 oz for my needs in case of receiving a container with an earlier expiration - I didn't need a whole pound or two anyway, and didn't want to store a much larger tub of this for as long as it would have taken me to get through a bulk sized amount. I'm very pleased with this purchase price considering the strength and quality of the L-Arginine, and I'm extremely happy about the rapid delivery period. The powder quickly dissolves with light stirring and a plain kitchen spoon is all it takes to achieve full dispersion, so no need to deal with the chunks that might otherwise occur when mixing it into water or another type of liquid, and no need for repeatedly shaking it like I've had happen previously with other brands. It's the perfect size and consistency for everything I wanted to use it for. I'll definitely order from Bulk Supplements again in the future when I'm ready for more! It works perfectly! It's got great effectiveness for those who use it for their workouts, and it also has other uses such as better sleep quality and just plain feeling good - and also, the primary thing I was particularly wanting it for... It's a great pH balancer for my DIY skincare and healthcare products! It's the best choice for an all natural pH balancer, instead of the riskier chemicals that many people are relying on for their formulations. Give it a try!

I have HBP. Been on Bulks Arginine and Citrullene as a stack on several other supps for reduction of that problem. I have a stack I call Jacked AS F@@@@ you can fill in any applicable word you like. My Normally 150/100 off Meds and 140/90 on meds gets reduced to a stable 117/78 if I stay off the caffeine. Ive changed my diet to be high P, Low C with modest fat to keep my brains healthy. 1 TSP of Arg, 1 TSP of Cit, 1 heaping TSP of BCAAi, 3 TBSP of Casein, 1 gram of Panax Ginseng (>10% ginsenosides), 1 heaping TBSP of Team Maca Black Maca Powder, a gram of Lysine, Jay Robb Whey (full serving) and Jay Robb Psyllium (full serving) in a 24 ounce shake, topped off with Kimbo Prestige Espresso beans ground Turkish (a full 1/5 cup). That is a stack folks. Its boasts nearly 50 grams of quick and slow release proteins, it has Black Maca for libido, energy, glandular (thyroid, hypo, pit) stability, ginseng for focus and clarity plus energy, Cit/Arg as a one/two punch to the vascular system for dilation and NO delivery and BCAA so I can continue to utilize the proteins and not catabolize lean muscle. Not a body builder, but Ill tell you on my small dose of meds I couldn't get my BP below 135/95. Today W/O caffeine I can be easily HYPOTENSIVE all day every day JUST ON THE ARG and CIT. All supps listed except Jay Robb and ginseng is all from Bulk Supplements. Prior I used the Bulk Supp Ginseng but found a gram did not have the impact desired and moved to another provider with higher Ginsenosides but the Bulk Brand was very good and Ill use it for my wife who is a bit sensitive to ginseng punch. Bottom line is that is my breakfast and Ive never had more energy with the slow release during digestion of the coffee beans, the long duration of protein availability----- blood flow---- clear mind (Im in a highly technical business and can't deviate for a moment during work)........ I follow up when I can with another 3 grams of each Arg and Cit midday and then at dinner the same (or nearly before bed). Bulk Supplements is nearly all i use and the value and performance is unparalleled. If you have HBP and don't have herpes of any kind (some folks are sensitive to Arginine) I suggest you get after lowering your BP and reducing your med intake. Ive tested the 3gram x 3/day Arg/Cit combo and it won't keep me normal after day 3. But stacking on my HBP allows me to reduce my med intake and stay in a really good range 24/7, even with my coffee addiction forcing the numbers up daily. The Bulk Supp product line is phenomenal.

Very impressed with the quality of this product. Extremely clean and does the job. Buying the powder in bulk lets me save on the cost while I also get to measure out exactly what I need. For those unfamiliar, L-Arginine has a number of excellent health benefits. It increases HgH (Human Growth Hormone) levels in men by way of a natural amino acid, making it a popular supplement for athletes. It does this by blocking the secretions of growth hormone inhibitor Somatostatin. It also raises insulin and creatine phosphate levels, helping with gains in lean muscle mass and fat loss. One European study had it boosting HgH levels to three times the normal level in one age group. Another way it's proven its cred is with guys with Erectile Dysfunction by increasing vasodilation. For this reason you'll find it in most over the counter stimulants intended to help with ED. It works by relaxing blood vessels, keeping arteries flexible which boosts blood flow. Taken in the right amounts it's also shown to affect a higher sperm count. And because L-Arginine increases NO (Nitric Oxide), which has shown to reverse arterial plaque, this helps in directly preventing cardiovascular disease. Manufacturers recommend a much smaller dose than the documented amounts shown to be effective, which is why I value being able to buy the bulk powder to customize my own measurements. Here's a general guideline for amounts/remedies with L-Arginine: Naturally elevated HgH levels: 3 grams 1 hour before exercise AND directly before going to sleep To Reduce Blood Pressure: 2 grams 3 times a day Erectile Dysfunction: 6 - 18 grams 45 minutes before sex Increase Sperm Count: 4 grams Total used throughout the day Healthy Heart: 6 - 13 grams Total used throughout the day Healing Wounds: 15 - 18 grams Total used throughout the day For me I take 3 grams in the morning pre-workout and 3 grams later in the evening before bed. I've found it really helps with my mood and energy levels, which directly improves my focus and concentration. I'm very happy with finding BulkSupplements on Amazon. Excellent customer service and speedy ship times. I'll definitely be back.

I like that this is straight forward Arginine in powder form. No fillers, no sweeteners, nothing extra. I add it to my protein and creatine powders and don't taste it. Only downside is that there's no scoop, so be sure to buy a set separately when you order. Or you can weight it out on a food scale. Since dosage varies by user, this makes sense.

To start, this seems a quality product and a great value. Combined with BulkSupplements L-Citrulline, I believe I experience the same effects as with much more expensive, premixed, flavored supplements. The problem lies in the flavor. I know, I know.. not everything tastes good and much that is good for us is fairly unpleasant, but this is exceptionally nasty to me. Something like a handful of effervescent cold tablets dissolved in canned tuna water. I tried masking it with many things. Fruit juices, drink mixes, strongly flavored supplements, sugars and artificial sweeteners, salts... etc. Nothing worked. The aftertaste was always there. I finally did a little research and found that the inability to mask this was due to chemistry. L-Arginine Base is just that, base. Meaning, it's alkaline and its high PH needs to be neutralized if there's any hope to cover the taste. We need acid to lower the PH. Some have used vinegar, some lemon juice, but I found what works best for me: https://www.amazon.com/gp/product/B00EYFKNL8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 . Citric Acid works amazingly well in a ratio of 4:1 Arginine to Acid, but I found you have to follow a process for maximum effectiveness. Start by dissolving four parts arginine in about half a cup of water. Dissolve it completely, which can take a while in cold water. (If you're doing keto, use your milk frother to speed things up) Next, add one part citric acid and dissolve completely. You should be left with water that tastes almost like nothing was ever added. You can, and I often do, add i tiny bit more citric acid for a slight sourness if you you'd like. Now add the water to whatever you'd like. I typically just add a bit more water and drink it down but might throw it in some tea or coffee or energy drink and it's undetectable.

Let me preface this review by saying I have never been diagnosed with an allergy in all o f my 60 years. Also, I have and continue to use other Bulk Supplements without issue. I have been "bodybuilding" and training ,most of my life and take many supplements (including multivitamins, creatine, beta-alanine, glutamine, L-citrulline, etc.) Over the past few months I have been experiencing nasal congestion, nasal drip, and a bad taste and smell in my mouth. Curiously, I usually noticed the bad smell and taste while I was working out (and breathing heavier). Over the past month or so the issue intensified and I went to an ENT doctor. I really thought I had sinusitis or possibly even a sinus infection. After talking with and examining me, he came to the conclusion that I had an allergy. I thought this was strange since I have never experienced an allergic reaction in my entire life and have not made any changes to my normal (clean, boring) diet. We did discuss the many supplements I take and he said I may want to start omitting them to find out if one or more are causing me issue. I still had my doubts since my supplement regime was basically the same for the past two years. Anyhow, over the course of several weeks I eliminated supplements one by one. Lo and behold, it appears the Bulk Supplements L-arginine was the culprit. I take a gram or so as part of my pre-workout. In retrospect, since I was experiencing most of the symptoms while working out, this started to make some sense. Wha didn't make sense is the fact that I have been taking arginine for several years, typically other brands in pill form. This was my second 1 kg bag of Bulk Supplements L-arginine and I can only conclude something must be different (perhaps a contaminant) with the current lot (bag) I have been using for the past few months. I am not sure if I will go back to other brands/types of L-arginine at this point but I will be more attentive and careful when I introduce other brands and types of supplements. My experience may be very unique but I thought I should share in case anyone else experiences the same reaction.

First of all, let's take a moment and wait for all the amazing, well meaning hippies and planet earth enthusiasts to leave this review section. Go on, I'll wait tilI I hear your birkenstocks clop clop clop down the hallway before I begin. Heaven forbid anyone of them buy a product that isn't made from 100% organic and blessed by New Zealand made vegetarian duck farts. Yes this product comes from China, so by default everything is evil and cruel in the world and toxic and we're going to give ourselves cancer because it's not double certified and and kosher blessed by a rabbi's fart to boot. Wanting to use this product wouldn't have ANYTHING to do with the logic in seeing 10K plus positive reviews stating how these products have helped people (rolls eyes). Now that it's just you and I, I'll continue. I'm here because I was searching for amino acids to buy in bulk without fillers. I wanted something priced fair and pure. After all my searching, Bulk Supplements had the ideal products. The only thing that was left for me to do was scan through all the reviews to see if such products would help me. I have a connective tissue disorder so I made it a point to buy all the aminos that had an effect in regards to tissues of the body. I also bought Glutamine as I read that helped people with their SEVERE bread/wheat/carbohydrate cravings as I have severe bread cravings for that and dairy. I work out often and can never lost the extra 25 pounds because of my food addiction to wheat and dairy. After one day I felt a difference so noticeable I logged in and bought the other remaining 4 amino Acids I needed but did not buy before do to not wanting to spend so much. But since they work and it seems most of these will last 6 months to a year, I opened the floodgates and bought everyone that was unique to me. I ended up buying about 8 products on my first purchase 6 weeks ago. Coming from someone who has tried adding coconut oil, vitamins, probiotics, nothing ever seemed to make much of a difference. It wasn't until I started taking amino acids that everything moved forward for me in my health goals. THIS......STUFF.......WORKS! I also have chronic fatigue syndrome and I'm seeing progress in my energy and health. I want to add that I also bought the Potassium citrate. I can't EMPHASIZE ENOUGH HOW MUCH THAT ALSO HELPED ME! I work out every other day and I use the sauna for about 40 minutes. In conjunction with taking aminos and now getting about 5K (4700 the average, but I workout hard) mg of potassium citrate, I'm feeling so much better! Even in my workouts I had to increase the weight by about 20 percent on the machines I use, and I even had to add more reps onto my sets! My original workout felt like I never even worked out since taking these products! Now even with added weight and reps onto my workout regimen, I still feel like I didn't quite workout enough! But I keep my increases minimal as I don't want to go ahead to much. But I can't flipping believe how much these products have boosted what I can do in the weight room AND not feel like a gassed race horse when I'm done. This stuff is literally the MAGIC powder. And with how its helping me with regular health outside of working out and also keeping me from falling off on binge eating on pizza and ice cream, this stuff is it. I'll always be a consumer of these products. Since I already ordered 3 times from this company (LOL) in the last 6 weeks, I got three free sample products to try that I WOULD NOT NORMALLY BUY! But since they also helped, I ended up adding them onto my next order! And to those people that complained about getting the free samples being just a marketing ploy and other nonsense, BUGGER OFF! There are products I wouldn't have bothered to try but since I got to try them for free and I liked them, I added them onto my next purchase. Because they worked for ME. You're getting a product that could very well last for a month and free shipping, all you have to do is leave a review if you like it or not. Yes, what a scam bulk supplements is running (rolls eyes). As of now there are two other products I plan on ordering from them, the Melatonin and the BCAA 3-1-2 product. Again, I'm only doing this because of how much positive gains I'm seeing in my health and workout. Another bonus was I could never eat enough meat, I was always hungry for tuna, turkey, beef, I could never get enough and my grocery bill was always high. Now I can eat a normal serving of meat and I feel like I don't need anymore thanks to taking the Acetylcarnitine and the Creatine, components that are found in muscle tissue. How I take my supplements is as follows- I take one serving size amount of each one in the morning. Then in the evening I take one serving size of only the msm, ascorbic acid, acetyl carnitine, Arginine, L-Glutamine, D-Ribose, potassium citrate. I take this because of budget, I want what I have to last longer, but these products are most important in keeping my cravings at bay so I take them once more at night. You can take some of these 3 times a day it says, but I only do them all once, and what I just listed twice. If I was rich and could afford $300 in supplements every 2-3 months I'd take them 3 times day. But since I'm not I make them last :) In summary, what I take is what I feel my body needs. And I am 100% happy with the effects I have experienced. And as for odors like some people described when they open their packages, well.........Some of these are chemicals, aren't they? MSM will smell like a sulphur like smell, correct? Unless you want added scents to mask things (which I don't) I honestly have not had a problem with that. And for the foil cosing bag, what I did was go to Walmart and buy a package of the large sized mason jars and I use those to hold my amino's in. I can't see knocking off a star because of the foil bag seal. Just pour it in a wide mouth mason jar and get a measure spoon to dish it out. If you're wondering what products I've used with this company, if you're reading this review then this is the product I purchased and have in my pantry. I'm not rewriting a review for each item, so I am copying and pasting a review to use on every item I bought from them. Any other questions please ask, but I find that as a person with health issues and food issues these items have helped me beyond anything else I've ever tried.

The quality is great. Have many items from BulkSupplements. Very consistent and accurate on dosing. This is a pure item, no fillers, no sugar, no stomach upset. Wife states it dissolves easily, but I just throw it in my mouth and chase with grapefruit juice.

Good
