D-Aspartic Acid (DAA) Powder

Key Features

  • 100% Pure D-Aspartic Acid Powder
  • Aid For Male Infertility
  • Testosterone Booster
  • Taste

  • Mixability

D-Aspartic Acid is an non-essential amino acid which is necessary for the development of the nervous system and the correct functioning of the neuroendocrine system.

D-Aspartic Acid 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 (equal to one teaspoon) or 3500mg (one half tablespoon) to be taken once, with the first meal of the day. Never go over the suggested serving amount, and do not take for longer than 8 full weeks at a time without taking a break in between of at least 4 weeks. The recommended dosage for athletes and people involved in strenuous physical activity often is to take one half teaspoon either twice or three times per day, and should be taken in between meals.

Customer Reviews

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.

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.

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.

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.

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.

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.

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.

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!
