D-Aspartic Acid (DAA) Powder

Key Features

  • 100% Pure D-Aspartic Acid
  • Aid for male infertility
  • Testosterone booster
  • Taste

  • Mixability

D-Aspartic Acid is a nonessential amino acid that is necessary for the development of the nervous system and the correct functioning of the neuroendocrine system.

This compound is just a bit less bioavailable than L-Aspartic acid, but it has a much more pronounced effect on increasing the release and the synthesis of testosterone. This is what makes it so accessible and popular in the fields of bodybuilding and athleticism.


Serving Size & Timing

The recommended daily dosage of this supplement is 2500mg (1 tsp) or 3500mg (1/2 tbs) to be taken once with the first meal of the day. This suggested serving amount should not be exceeded, and it should not be taken for longer than eight full weeks at a time without having a four-week break in between courses. The recommended dosage for athletes and people involved in strenuous physical activity is to take 1/2 tsp either twice or three times per day between meals.

Customer Reviews

I am going to continue ordering this product (D-Aspartic Acid) and other products from Bulk because they have high-quality products with free and timely shipping. I am currently off cycle, 67yrs old. My libido was down. Started taking this product and in 3 days started to feel libido returning and my strength in the gym is still rising. I would recommend this to everyone going into PCT

On 9/10/2015 WILLIAM said...

The quality of this DAA is equal to or better than other suppliers. Clean crystals that dissolve in water with some effort. Light sour taste.

Have noticed some increase in morning "excitement" after taking this product for a few days.

On 8/31/2015 Brian said...

Product came very fast and was exactly as it should be. This seems to be a great product. Using it as a testosterone booster.

On 8/26/2015 alan said...

I will definitely order more, mixes easily in water no after taste

On 8/5/2015 mitchell said...

This is the first time I've tried this particular product. So far, I enjoy it. It doesn't dissolve the greatest, but I had read about that beforehand, so I expected it. Not really a big deal; it goes down easy enough. I mix it with another flavored drink, so I actually don't taste it. But I was curious about it and tried it on its own - doesn't taste too bad. The description is accurate. Sort of citrus flavor, but not disagreeable. I will probably buy more in the future, and I would recommend this product to others.
I haven't been taking it long enough to see results while working out, or in other areas, but I optimistic about it!

On 8/4/2015 Thomas said...

This DAA powder is great quality for a great value and arrived promptly will order again

On 8/1/2015 David said...

I'm 63 years old and have been bodybuilding since I was 16, when I actually competed. I have seen and tried all the testosterone boosters on the market. None really live up to their advertised benefits. A lifter at the club told me about D-Aspartic Acid so I tried it and it took a few days but you could feel the benefits. Increased endurance, strength and mood. Needless to say I bought it again.

On 7/28/2015 Raymond said...

Great energy product does wonders, in the bedroom!

On 7/24/2015 Jermaine said...

I'm 63 and have been bodybuilding since 16. I competed in the amateurs. This is by far the best testosterone booster that actually works. It provides, endurance, enhances strength, and muscle recovery with no side effects.

On 7/21/2015 Raymond said...

It's very clear that you get a quality product from this company.. taste isn't very strong and it is really only missing a measuring spoon. I feel especially with daa that it would be nice to have but at this price it simply can't be beaten.. Thanks bulksupplements, you have a customer for life.. also extremely fast shipping completely across the United States.

On 7/18/2015 Daniel said...

I tried the product, and did notice a difference,, especially with my workouts. I will but it again

On 7/15/2015 Keith said...

Looking forward to great products at great pricing from now on!

On 7/1/2015 scott said...

Another great product from Bulk Supplements! Taking with my first meal of the day to boost free testosterone. This stuff works pretty well. Much better value here than at your local supplement store. Plus, you pick the dosage. I use 3G the first couple days then bump it up to 5g. Thanks for another great product!

On 7/1/2015 John said...

I feel like this product increased my lifts within days. I take around 5 grams with my first meal daily. It does give me some gas and occasional mild diarrhea. I felt generally stronger and my libido seemed to increase immediately. I have been using it for about 10 days now. I will probably discontinue it after 14 days, then take some time off before cycling again. I like the product, it seems to give me a strong short term boost to my workouts. I will purchase it again.

On 6/30/2015 Bradley said...

After about a week I felt the impact of this product. More restful sleep, faster recovery between workouts, and a better sense of well- being.

On 6/25/2015 Athanasios said...

I am an older gentleman who has been concerned since my youth about being fit (and virile) as I age. I have studied the question of lower testosterone in the elderly and have concluded that having my body naturally create the hormone is the optimum way to solve the problem of "Low T"
D-Aspartic acid is a new addition to my menu of supplements. I am on my second batch with this latest order. My wife and I are very happy with the results.

On 6/23/2015 James P Savage III said...

All DAA powders have a hard time mixing so it was no surprise that this one does too.

Aside from that though this DAA does a great job in assisting testosterone levels.

DAA is super tart and acidic. I recommend mixing with orange juice to mask it a bit.

On 6/10/2015 William said...

I stack this with Beta Alanine, L-Citrulline DL-Malate 2 and BCAAs. I have to tell you once again I am impressed by the quality of products from bulksupplements. I started feeling a difference on the third day of taking this. I will be reordering this without a doubt.

On 6/3/2015 John said...

I just started using this product. I purchased it for the Male-T factor. I have noticed a significant increase in strength and endurance in my workouts. Mixes easily with my pre-workout L-Arginine AAKG that I purchased through also.

On 5/20/2015 Thomas said...

Im an older Man with low testosterone levels and I have been taking D-Aspartic Acid for about 10 days now and I am seeing very good results! I'm growing and my strength is increasing now also. This is some exciting stuff. A body builder trainer told me about this stuff so I knew it would work, but you never really know it will work for you personally till you try it. This stuff really works for me!

On 5/17/2015 Randy said...

My order came super fast and I'm enjoying it so far, i feel a noticable bump right off the get go and am excited about using the product.

On 5/16/2015 Travis said...

I've recently started taking it and have already felt a difference in my work out. Great product and reccomend it.

On 5/8/2015 alexander said...

In late Aug 2014, I did a testosterone pellet therapy to increase testosterone levels as I am 50yrs old. The therapy would last 4-6 months depending on how much you exercise. About 2 months in, I found out that once you go on this route, the body reduces or stops its own testosterone production. I decided to search for a different way. I came across D-aspartic acid along with a few other things, but have decided on this and goji berries.

I am very happy with the results and will not go back for the $700.00 treatment. I will save my money and my body's testosterone making capacity. Thanks for a job well done Bulk Supplements!

I also use your BCAA, AAKG, Citrium Malate, Methionine, and Carnitine from you for pre and post work out drinks. Will be trying your Creatine and Whey Protein when my current supply runs out. Your quality and prices are unmatched!!

On 4/27/2015 Courtney said...

Not only did this product get to me before the estimated ship date, but it also is one of the best DAA I have ever used. Noticed almost immediate results and mixes very well with water. This is one of the few DAA I have felt a boost in my test throughout my entire usage. I would recommend this product for anybody looking for a good, pure, and safe way to boost natural test levels

On 4/25/2015 Colin said...

Love it! Even with time off from the gym. With this, my body hold muscle mass longer. I can maintain what I've been working on without any worries...

On 4/25/2015 Joshua said...

I was taking the powder version and I am glad they came out with the capsule version. I have a crazy schedule that changes every time and for me capsules are more portable, plus I get the right dose, no more guess work. Thanks for putting DAA in capsule form.

On 4/23/2015 Reginald said...

Bulk supplements comes correct 100%. Pure pharm grade supp & had it in 3 days. Real d-aspartic in legit dosing gets you feeling like a man-champion. Just turned 35, best diesel shape of my life. Good job BulkSupps.

On 4/19/2015 Michael said...

I recently ordered 500 grams of DAA. It was shipped to me in less than a week and I was very pleased. It was well packaged, had clear instructions on dosage, mixed well, and most important I can always feel the difference in my natural test levels when taking DAA. I would recommend this product to anyone looking for a good test booster.

On 4/13/2015 William said...

Great product. Mixes well (mixes best with juice or water, don't mix in protein shake or with milk - very sour). Over all improvement in how I feel, strength and well being definitely up.

On 3/18/2015 Todd Williams said...

I stack this with Beta-Alanine and have noticed much more energy. I just turned 40 and have been working out my whole life. This product is legit. It is the purest and best one I have found and will continue to order.

On 3/7/2015 Daniel said...

I stack 2 grams of this w/ 400mg of caffeine and 3 grams of Creatine
as a pre workout
This stuff is awesome, showed noticeable difference in my sex drive and helped with keeping up that "beast mode"
this works

On 2/24/2015 Dennis said...

Great product, Bulk Supplements deliver quickly, And products are top shelf, Notice the difference in the way I feel and ordered more great products, Thank You

On 2/24/2015 steve said...

What a great product. It mixes very well with water or juice and at the gym I feel stronger and have a lot more energy and longevity. Would definitely recommend this product to anyone.One tip that I have is pair this with citrulline if you are going to the gym great combination from bulk supplements.

On 1/2/2015 Mark said...

I've never taken D-Aspartic Acid before and was completely in the dark about it's benefits. I stack this with Beta Alanine, and L-Citrulline DL-Malate 2:1 and completely eliminated the need for caffiene (letting adrenal glands rest).

My sleep has improved, breathing is more deep, and my workouts have improved. It also provides a feeling of well being and libido is increasing.

I was amazed at how fast the product came. Ordered on a Friday and was received on a Monday. I will continue to order more products from BulkSupplements and make my own "supplement cocktails" instead of all the fillers in other supplements.


On 12/18/2014 Ian said...

My package was delivered quickly in a resealable bag, which is great, but the product works, which was my main concern.

I feel awesome on D Aspartic Acid, and will continue to buy from because they have proven themselves to be reliable. If you're a man and you love lifting weights or having sex multiple times a day, give DAA a try, you will not be disappointed.

On 12/9/2014 Marc said...

Great product, could tell a difference in libido and well being. Mixes well and easy resealable packaging. Well keep buying.

On 12/3/2014 Ryan said...

They shipped the product quickly and the quality is the best I've found anywhere.

On 10/9/2014 George said...

This is by far the best DAA product I've ever used. My shipment came quick and and the strength gains I've made so far are incredible!

On 10/9/2014 George said...

Love the resealable aluminum foil package. Keeps it dry and mess-free. Secondly, it mixes easily with my smoothie. After taking this it made me feel as if I could run through a brick wall. I will definitely be adding this to my daily regimen. This is the best price I've found and the quality is excellent.

On 9/28/2014 Joseph said...

I received my order very quickly. The DAA powder is pure and potent and noticeable effects after a few days. Increased Libido and positive feelings. I will purchase again.

On 9/15/2014 Joseph said...

Great product I could feel it working within days. I feel great. Like I am the alpha dog.The taste is a little bitter but can get past that. Product mixes pretty good.I will buy again when its time.

On 8/4/2014 Chad said...

I was very satisfied with my experience from Bulk Supplements. I received my order very quickly which was the first positive. The second, is how shocked I am by the quality and purity of the powders. This DAA powder is pure and potent and noticeable after a week or so of solid use. I've used other DAA products in the past which have taken twice as long to kick in. My sleeping habits have been great while using this and my libido is through the roof! Not to mention the focus and energy I'm feeling while in the gym which is really why I took this product in the first place.
Overall, this product has surpassed my expectations and I will definitely be ordering more in the future.

On 7/30/2014 Trevor said...

I recently started to use DAA as a supplement and its still early to tell results. I have just received a scale to ensure I am using the correct dose. But I am sure that Bulk Supplements is offering quality products at a great price. I will update reviews of there products as I get more results. But I recommend this company to others. Thank you Bulk.

On 7/27/2014 Douglas said...

Great product for those looking to increase their Testosterone naturally. Product ships fast, and is of high quality. I'd recommend it.

On 7/26/2014 User said...

This is a great product for test support, or cycle support. It's also good to just take for libido. Love the pure products from BulkSupplements. Fast shipping I got my order in 4 days!

On 5/11/2014 Kyle said...

II've tried this compound before in bulk powder as well as a more commercial
capsulated form. The research surrounding the efficacy of DAA is disputed
to some degree, but I can attest that it does promote short term increases
in free testosterone. I separately control the chance of elevated estrogen
levels with other medication, which I would urge you to research. Overall,
the product is as described, and dosing 3g in the morning on an empty
stomach has overall provided good preworkout results in terms of vascular
performance and stamina. Recommended for use as a moderate short term
natural testosterone elevator.

On 4/22/2014 Adam said...

First, Bulk Supplements got my order here so fast; like a few days. I've had to track down packages, call companies, resubmit orders, but not these guys. Fastest service I've ever experienced. I'm 34, just starting the road back down the T mountain, and a month of D-Aspartic at this quality makes me feel powerful, my girl definitely appreciates the effects, i slaughter the gym, and my physique is ideal with a clean diet at about 9-10% body fat. The metabolism I lost with age can't be reinvented, but it can be mitigated, and this is a factor in keeping me lean and virile naturally. Great company, great product.

On 4/16/2014 Michael said...

I have personally found the D-Aspartic Acid from Bulk Supplements to be of very high quality, and it definitely gives a testosterone boost when taken. At 52 years of age, I can notice the difference when I take it, and the effects are very noticeable. I have used it in some of the formulations at my supplement store, and it has proven to be a very popular product due to it's efficacy. I highly recommend it!
