AAKG for my Horse
My son is a body builder and has been purchasing AAKG from Bulk Supplements. He is very happy with it and the gains that he is getting from his supplements. I needed AAKG to treat a condition in one of my horses. Bulk Supplements quality is far superior to the equine products and has a much better price! A definite win-win. My horse is clearly feeling better already! Great product for man or beast! *

I use AAKG in a pre workout drink. Along with helping with endurance it gives a good pump! BulkSupplements has the best prices and fast shipping. *

On 2/20/2018 Brandon said...

Effective arginine supplement only thing that caught me off guard was silica gel package in the arginine supplement. I have ordered here before and never seen silica gel packets in my supplements until now. In America we do not use silica gel in food related products. It makes me not want to order supplements here but besides that I have had a good experience at bulk supplements*

On 1/1/2018 Eduardo said...

AAKG is the best
I love this product. When used as a pre-workout, it provides noticable endurance without the feeling of a harsh stimulant. When used for recovery, it helps alleviate soreness and "creaky" feelings after going to the gym. I am able to work a physical job 5 days a week and still go to the gym on 4 of those nights. Very under appreciated product- give it a try!

Shipping was very fast and BulkSupplements customer service has been great!*

On 9/27/2017 Justin said...

Great Stuff!
I have been taking this product for just a week (2 grams 30 minutes before bed) and already I feel that it has helped me tremendously. Muscle fatigue is lower than it has been and my pumps while working out have been intense! I will definitely recommend! *

On 9/21/2017 Kaci said...

Good addition to homemade preworkout
I've noticed since taking this that I no longer reach failure from lactic acid burn and can work to true muscle failure. Mixes a little funny but no complaints on the effectiveness. I recommend this product.*

L-Arginine a-Ketoglutarate (AAKG) Powder
I buy this products in powder form from I started on June 10, 2017 and after 3 days I noticed that my BP readings were a lot lower. After 10 days on the program I had to take half of the blood pressure medication because some of my readings were as low as 88/52.
In the morning of June 30, 2017 it was at 102/66 which is great. I used to have 130/90 in the morning. Today July 25 it was 113/72.
Now I take 4.5 gram of L-Arginine and L-Pyroglutamate Powder which is premixed by and add 1.5 gram of L-Citrulline Powder. I mix it with about 4-5 ounces of fruit juice and take this in the morning before or after breakfast*

On 8/8/2017 Rudi Londt said...

This product is just what I was looking for for my own PWO mix. Better stamina within a week already. I like the ability to add more than is in most name brand PWO. Will order again indeed.*

Awesome Product
I take this PWO with Creatine and have noticed a better pump immediately. Definitely adds more stamina and vascularity to my workout.*

On 5/3/2017 Spiros said...

increased vascularity and increased stamina
I take this with my PWO combined with L-Citrulline, Creatine, Beta-Alanine, TMG, and I have noticed increased stamina and vascularity as well. I highly recommend this and it is at a cheap price. I only take 3.5g and that is fine for me.*

On 3/28/2017 gerald said...

Gives A Fuller Pump
I use 5 grams 30 minutes before I workout. The increased blood flow adds stability to my joints and a better pump to my muscles.*

On 11/28/2016 Brian said...

L-Arginine a-Ketoglutarate from bulksupp is excellent Quality
Bulk Supplement’s L-Arginine a-Ketoglutarate (AAKG) is a superb product. I looked at the ingredients of popular retail supplement brands, and found that many of the basic ingredients can be purchased online here at Bulk Supplement at a significant per serving price savings. With a little do-it-yourself initiative, one can stop spending money on the brand/coloring/flavoring/packaging of the retail favorites, and get the basic ingredients here at Bulk Supplement. For full disclosure, I have to make a higher initial investment to get the ingredients I want and many of them don't taste the best without flavor enhancement. If one is serious about his or her supplementation for workouts or general health, in my experience at Bulk Supplement you get well packaged quality ingredients that arrive on time and will save you money on a per use basis over time.*

On 11/28/2016 Viet said...

Nitric Oxide Booster
As a Sports Nutrition Coach, and Triathlete, I am looking for ways to keep Nitric Oxide levels up throughout the day, well beyond the usual pump experienced with L-Arginine. AAKG works as a "timed release" Arginine and when combined with L-Citrulline DL-Malate and BeetRoot powder (both available from BS) keeps NO levels up, which sinificantly improves the quality of my training.*

On 11/15/2016 James said...

L-Arginine a-Ketoglutarate (AAKG)

Taking for Blood Pressure & Increased Energy Level
I recently switched from BS's L-Arginine to L-Arginine a-Ketoglutarate (AAKG) after reading this form was more effective. Studies have shown it to increase blood flow and reduce blood pressure. I'm taking it to help with my blood pressure. My BP's usually been in the normal range with both regular Arginine & AAKG. I have also noticed a difference in my energy level and endurance when taking this. Like all BulkSupplement products, this is a high quality product at a significant price savings over other companies. Thank you, BulkSupplements.*

On 10/1/2016 Kenton said...

Just started using it. I have ALS and it was recommended to me for muscle strength. It will take another two weeks to notice anything but I do feel a slight difference. The price is right and the service impeccable. Thanks*

On 9/26/2016 terry said... AAKG, IMHO
I think that different product formulas work differently on different folks. This isn't to state the obvious necessarily, but to remind everyone that what works for some may not work for others. In my short experience with the AAKG from this site, it seems to be somewhat effective. I have been pretty healthy my whole life, and while this does not make me feel like I am on a rage. I actually like that. I usually work out without using a pre-workout or caffeine (just a healthy meal a few hours prior, or on empty if morning PT), but I read about the benefits of AAKG in aging men, and I thought I would give it a try. I think it was worthy trying out, and so far I am content. I like being calm the whole day though, even when all I do is deadlift, squat, bench, and OHP for lifting. The rest is running, swimming, calisthenics, rucking, and joking around. This has not made me anymore calm nor aggressive. Whatever it is you all are looking for, and you try this out, I hope it works out for you.*

High Blood Pressure
I purchased this product along with Pine Bark to give to my 55 year old husband who has high blood pressure. I am giving him 800mg's of Arginine and 150mg's of Pine Bark daily. (According to medical study done for high blood pressure) It has been about 10 days and his blood pressure has dropped into the normal range. He had a doctor appointment and his Doctor was pleased. My husband feels great and will continue on this product. Quality is excellent and I would recommend it!*

On 9/12/2016 Rhonda said...

Great product, adds a kick to the intensity of your work out. Easy ordering, great price and fast delivery. *

On 9/8/2016 Rich said...

AAKG, it is a well research supplement/amino acid
Personally, I believe a real food diet, sleep and working out is 95% of building a great healthy body. After these 3 staples are down I believe its then proper to use supplements. This is where you can achieve that edge after you've put 100% into your fitness goals. AAKG is one of the few supplements that works very well and noticeably. There are other supplements that will help assist you in your goals but certain supplements such as L Arginine, Creatine and the like, will give you, through time and effort, positive and noticeable results. Im using this to build muscle, but also on the same token this supplement increase overall blood-flow in your whole body, so if your eating healthy foods and working out this supplement is also assisting your body delivering nutrients throughout your whole body.

Great product, a very pure product, and I do recommend this over any 'pre workout' any day. Why not buy 10 great products from bulk supplements for around 100$, create your own prework with ingredients that are pure and at high doses, and have 100 or so servings comapred to a 50$ preworkout with unknown ingredients and stimulants with only 30/15 servings..... Give it a try*

On 9/7/2016 Brian said...

AAKG Must Have
This product provides amazing vascularity/pump! This product will assist with the development of lean muscle.
Mixes well with my other pre-work out supplements.
I highly recommend this for anyone that wants to get the most out of their work out regimen. *

Quality Product. Really helps with blood flow. I seem to have more energy to work out and do yard work. The delivery was quick with no problems. Thanks*

On 7/7/2016 Larry said...

I love this product. Nothing gives pumps quite like a good dose of AAKG (5000mg). I stack this with Beta-Alanine (3000mg), pre-workout, along with Creatine Monohydrate (5000mg). All from Bulksupplements. Best non-stimulant pre-workout hands down. You don't need a fancy label to get amazing results!*

L-Arginine a-Ketoglutarate (AAKG)
this is a great produce, the addition of aakg is very comforting because it nitrogen fixes so excess protein won't be detrimental to my health, I'm not a huge fan of the taste but it is easily maskable with a sweeter protein shake.*

Get's me "jazzed" for my workouts !
I stumbled onto Bulk Supplements on another website while looking for supplements. I decided to go directly to their website and deal direct. I LOVE what the AAKG does for my workouts and my overall feeling of health and well-being. My my blood flow seems to surge within 1/2 hour of taking it in my protein shake in the morning and right before my workout, as well. I'm a 58 year old martial artist and "gym rat" and I can safely say this is one of the best supplements that I have ever found for increasing capacity and enjoyment of all my physical activities . The powder is clean and pure and makes me feel great ! Grab some won't regret it ! I'll be back to Bulk Supplements for all powdered supplements now !*

On 1/12/2016 Richard B. said...

AAKG Review
This is a great product. This is the first time trying it and I love it. It mixes very well and I can feel a pump during my workout. I would recommend this arginine to anyone mainly because you don't get all the added chemicals that come with other pre workout supplements.*

On 12/3/2015 mark said...

In the past, I bought pre-workout's from health stores. They were expensive and had a lot of stuff in there that I didn't like: mainly caffeine. I get enough of that from the coffee I drink.. So, I have been using Bulk Supplements BCAA along with Bulk Supplements Arginine AAKG and Bulk Supplements Glutamine. I have been doing this for a while now, and I can safely say, the product's clean, no fillers, I get pumped up, not jacked up. I find myself sipping on this formula through out the day and stay pumped..*

On 11/19/2015 Jordan said...

Works well, despite research saying it doesn't
I definitely noticed the effects of this product right away on my workouts. I combined it with BS's citrulline malate 2:1 and...WOW! Although I can't say I noticed any difference in terms of my "pump," but my strength and endurance has definitely increased. I keep a detailed log of the reps x weight lifted for every workout, and in the past, I sometimes was able to beat the previous workout, and sometimes not. Since taking the AAKG with citrulline, I am consistently smashing my "records" from the previous workout.

I was a bit hesitant to try this product since most research studies have suggested that arginine has little or no effect in well-trained athletes. I beg to differ. Awesome product!

On 7/26/2015 Mari said...

By far, more cost effective than buying NO2 in the store. The very first day I tried this product, I used the name-brand recommended dosage as my starting point (i.e. about 3000mg). The effects were a lot stronger and immediate than the name brand, so I actually had to decrease my serving size. Guess that's the difference between taking something with a bunch of fillers, versus using the pure stuff. Plus, it is about a hundred times cheaper (not exaggerating) to get this through Bulk Supplements. *

aakg powder
i really liked the taste of this powder in water. was kinda like a sweet lime aide of sorts. easy to mix and drink. i was tempted to pour the whole bag in the glass. only tried it 3 times so far before workouts but I believe it helped me maintain better endurance during the entire period. i look forward to more test. so far because of the mild taste in water i love it.*

L - Arginine a-Ketoglutarate (AAKG) - Excellent!
I was hoping to have better blood flow throughout and better water removal, plus more energy to work out on my old Soloflex muscle machine. I have better sweats...better energy to complete the Soloflex workout and more. More step to the walking. I also do hatha yoga for added flexibility. I love this AAKG! I am 67 as of yesterday.*

On 6/8/2015 Robert said...

Best for preworkout
First off let me tell you how much you will save shopping here vs any other leading brand. It's bulk and it's cheap and the quality is as good as any other that cost 10s to 100s times more. Yes I said hundreds because look at how much you get and how long it will last. Plus with this L-Arginine it will last me 6 months where the other brands will last a month and I will have to spend more and more frequently. Every preworkout should have this! This stuff rocks. Good pumps. The burn stays but it's good! You have to get this with the Creatine. Works great together. Thank you bulk supplements and having, in my opinion a superior product. *

On 6/7/2015 Lance said...

This product is the best stuff for pump and strength. Huge pumps that last what seems like forever. It also is great for getting vascular. I would recommend this to anyone. Gonna keep ordering this by far amazing.*

L-Arginine AAKG
I am on my second order of this product. I did not like other pre-workout powders from other companies as I felt there was too many fillers added to their pre-workouts. But with it is all pure and you get the real deal. Since taking their products I have seen an amazing strength increase and amount of mass.*

L-Arginne AAKG
I love this stuff since it does help me with overall vascularity and therefore higher volume of nutrient and oxygen transport. My pumps are definitely better since incorporating this product into my pre workout cocktail. Using BulkSupplements allows me to economically use the amount that I desire which is great. I highly recommend giving it a try.*

great product
I used to buy nitric oxide booster, but now make my own. This is the main ingredient. Mixing your own saves a lot of money and you can tweak your formula To find what works for you.*

On 4/15/2015 erick said...

I bought this as i wanted a preworkout that is just going to give me a good pump. for the past few years i have stayed away from mainstream preworkouts as i have a heart condition and they usually just pump those crap with a lot of caffeine and other stimulants with random fillers that are under a vague "energy blend" it puts a lot of extra unnecessary stress on your heart that is just not good in the long haul. This does no such thing as it just makes me feel as though my workouts are satisfyingly intense and really does create a pump not experienced with no such preworkout. works for me*

L-Arginine AAKG
This product arrived quick and efficiently. This is used as a "pre- workout". I mix this with my Bcaa's and off we go. During strenuous activity this allows my muscles to be fuller and responds well to increased exertion. "the pump" Great product works well alone also with proper nutrition.

Thanks Bulk Supplements*

This works great. I combined it with beta alanine to make my own preworkout and I am very satisfied. If you would like to take your workouts to the limit this is the supplement for you.*

On 3/18/2015 Todd said...

I use AAKG now and just ordered this, I can't wait to try it. AAKG gives me the pump I'm looking for when I'm lifting. I know this product will be great just as all of the other supplements I buy in bulk from here.*

AAKG -- Essential to a pre-workout stack
I take AAKG before working out to achieve greater blood flow to muscles and a better pump. This stuff is is essential if you want to maximize your workouts. *

On 3/6/2015 Conrad said...

Good pump from AAKG
While I am unsure if this product directly helped me gain muscle, I have enjoyed workouts more while using it along with Citmal & OKG. I have experienced greater gains over the past six weeks using these supplements then I had the previous six weeks using creatine alone. I think this may be due to greater intensity of the workouts that comes with satisfaction of the pump. Recommended.*

On 3/6/2015 Joseph said...

Finest Arginine available in powder !!
We take this AAKG at night in a 2:1 with OKG and Glycine -- excellent results for sleep and release of HGH (human growth hormone) over-night -- we always feel more energy in the morning on those nights after this mixture !! We also mix it in whey protein isolate.*

On 3/5/2015 RONALD said...

This definitely gets me pumped.
This is my second time using Bulk Supplements AAKG. I received a sample before from a previous order and I was amazed by the dramatic effect it had on my workouts, I would even say it works better for me than Citrulline Malate. So this time around I dropped the L-Citrulline Malate and bought some more AAKG.*

Way better than expensive brick and mortar capsules
Ok I will review this product on 3 levels: Price, availability, and function

Price: I had been getting my Arginine caps at Walmart for $6/ 10 day supply or $0.60 /day. Here I bought 500g which is a 100 day supply and it for 21.96 which comes out to about $0.22/ day, huge savings.

Availability: At the walmart it was hit or miss if I could even find it in stock in the 1g dosage and the 500mg dosage was twice the cost. Here I ordered and in 3 days it was on my door step.

Function: Been using the Bulksupplements Arginine for a few days and and other than being easier than swallowing a hand full of pills it seems to be functioning in the same manner as the capsules. I mix all of my supplement powders with 1 Tbsp of crystal light lemonade and 16oz water and cant taste anything but the lemonade so far.

Out of these 3 areas I have to say that I will be a Bulksupplements customer for a long time and give this product a review of 5 STARS.*

On 2/28/2015 David said...

i use this as a post work out
I use this in my post workout shake or meal. It helps with soreness for sure. It came FAST also, like within the week. Well worth the time and $$$*

On 2/25/2015 Dennis said...

Great product I usually mix with water, Beta Alanine and DAA for my preworkout!*

On 2/23/2015 Aaron said...

Great Blood Flow and Pump
Taking this supplement pre-workout helps increase blood flow to the muscles and helps improve muscle pumps. I certainly notice a difference when taking this supplement, in both pumps and vascularity. After taking around 5g pre-workout I was left with better than normal vascularity even 2-3 hours later. *

On 2/23/2015 Brent said...

Energy Drinks
We use this product in combination with Bulk Supplements ALCAR for my entire household.

With a few of us hitting the New Years fitness Bandwagon, and a couple of us just using it to help with the vasodilation for getting through tough days on the feet, it has proven to be invaluable.

The extra energy from the Alcar and the reduced inflammation from the AAKG, I can say if you struggle with the second half of your day, before or after workouts, both of these products with a little Mio or other water flavoring will provide you with what you need.

Will definitely be getting more of this in the future and have passed this formula along to friends and family who have also started purchasing from BulkSupplements.*

L-Arginine a-Ketoglutarate (AAKG)
Excellent Product. Clean, pure, strong and very effective Arginine AAKG! Have tried other brands Arginine which usually has a slight sour/bitter taste, but product is almost tastless. Excellent. Works very fast and the pumps were good!! Product was delivered very quick. Highly recommended!! *

On 1/6/2015 BLP said...

making my own pre-workout
I just wanted to say that I have never bought bulk supplements before, but I had been trying different types of Pre-workouts, and was getting tired of paying insane prices, and now I can make my own with the product that you have it has worked great, and at a fraction of the cost!*

On 1/5/2015 John said...

Arrived Early and Dissolves Well
First and foremost, it should be made clear that for customer service aspects of this item it would receive 5 stars. I ordered the item and was told the expected delivery date was Tuesday of the next week. It arrived on the Friday of the same week.

Second, product only gets 4 stars from me because I dissolved it in both plain water and with an amino acid product I use. Both times there was a slight grainy texture to the drink but there was no taste to the powder. I can get the grainy texture to go away if I dissolve the product in warm/hot water, but no one drinks warm water. As for the results, I definitely received the boost in blood flow and the muscle pump I had been hoping for so good job there.

I will definitely buy the product again.*

Great product half the price compared to other vitamin stores. I like the pure powder form seems to work faster and better. *

I really feel the Muscle fullness, I take before workout and after workout,one hour later take my post protein sake, my Muscle feel full for hours. *

On 9/24/2014 Timothy Rodriguez said...

Solid Product
I like the fact that 1 teaspoon is all that's needed to achieve the same results as a massive scoop of most preworkouts.

My Preworkout ingredients:

Half a teaspoon of BCAA, Beta Alanine and Tea Extract; one tea spoon of Creatine; two scoops of Gatorade Powder.

No fillers and other weird "propriety" ingredients that the majority of preworkouts include.*

Pops my Veins out!
I stumbled onto Bulk Supplements while searching for plain L-Arginine. The AAKG supercharges my blood flow within 30-45 minutes. The blood vessels pop out and I'm ready for ANY physical activity. I'm 66 years old and am so impressed with what it's done for me I'd like to encourage any male to grab a kilo of the AAKG right now to increase their performance in ALL physical activities! Bulk Supplements is where I'll go for all powders from now on!*

On 9/11/2014 Kirby said...

Simplified supplementation
This is a great product and as far as I've been able to tell is exactly what is advertised. I love being able to individually mix my own aminos together into a preworkout formula, which is what I use this particular supplement for.*

On 9/8/2014 Christopher said...

Since I began using L-Carnosine with BulkSupplements L-Citrulline DL-Malate 2:1 and L-Arginine a-Ketoglutarate powder I have noticed mood enhancement as well as faster muscle recovery and greater endurance in the gym. My dosage is 1/2 teaspoon L-Citrulline DL-Malate and L-Arginine a-Ketoglutarate plus 1/4 teaspoon L-Carnosine Powder 3 times a day dissolved in water and taken on an empty stomach. The first dose is taken in the morning upon awakening. The second and third dose are taken before and after resistance weight training. The taste is very palatable with a light lemony flavor due to L-Citrulline DL-Malate 2:1 being composed of citrulline attached to malic acid. (Malic acid helps your muscles to use the lactic acid that builds up when you work out, which actually helps prevent fatigue.)

By maximizing my nitric oxide production which results in blood-vessel dilation, I'm getting more blood to my muscles before and after workouts. This helps to deliver more oxygen; more nutrients, including amino acids, glucose and fat; more anabolic hormones, such as growth hormone and testosterone; and more water (your blood is actually mostly water).*

On 9/2/2014 Rahul said...

Great product with a great price
The price for this product is OUTSTANDING...

I'm very happy. I can dose this stuff at 10gs a day without batting an eyelash.

I will continue to buy.*

AAKG - Best Value Quality
This is a great value and the quaility of the AAKG powder is supieror. It mixes completly. I have shopped around and Bulk Sup. has the best prices/vaule for AAKG Powder.*

Awesome Product!
Have supplemented with L-Arginine for a number of years now. This product has exceeded my expectations. I have recently taken L-Arginine AAKG in conjunction with Citruline Malate and the effect is rather phenomenal! One serving 30 minutes before my workouts and another serving right before bedtime along with L-Glutamine. My recovery time has been remarkable as well as my energy levels during my workouts. I supplement with other supplements from Bulksupplements and can say without a doubt that this particular L-Arginine is going to be in my supplement arsenal for as long as I am able to hit the gym! *

On 7/16/2014 Henry said...

Awesome pump
Very happy with this product. Could not believe how swollen my arms were for my first workout with it.*

Massive PUMP in the GYM
Wow, endless power, and pump. Mixes easily and now I can finally load up with clean power--I can't say for sure if it's the Glutamine, BCAA's, Citruline Malate, BetaAlanine or the Creatine--since I'm taking ALL of these and got 20-25% increase in power AND endurance!!! AMAZING. Also lost a few lbs of FAT!*

AAKG review
Defiantly increases blood flow during workouts. which helps with better performance and longevity. I hear it also has works for better vascular activity . I haven't seen anything as far as that goes but as for increased power and blood flow it works pretty well. In conjunction with other supplements it stacks well. *

On 4/22/2014 Kevin said...

L-Arginine AAKG
I love the simplicity of using basic forms of L-Arginine. The powder mixes great with other powders and I can't taste it when mixed with protein. I'm very impressed with how the powder can mix and notice that it gets into my system faster then any other powder I have tried.

BulkSupplments are a hidden gem and I'm glad I found them! *
