What is D-Aspartic Acid?

D Aspartic Acid has come from nowhere and taken the male hormone supplement market by storm. Research has shown that supplementing with D Aspartic Acid resulted in a 45.5% increase in levels after only 13 days – at the cheapest price in Europe, this really is ‘Stop Press’ for all size, strength and power athletes!

D-Aspartic Acid is the D-form of the amino acid aspartic acid. Supplementing with D-Aspartic Acid has been shown to on average increase hormone levels in males by 45.5% in just 13 days!

Where to find D-Aspartic Acid: D-Aspartic Acid is produced naturally in the body from the non-essential amino acid L-Aspartic Acid. Within the human body it is found in high concentrations in areas where hormone production takes place. The hypothalamus, pituitary gland and the testes therefore, all have high concentrations of D-Aspartic Acid.

What are the performance benefits of using D-Aspartic Acid?

A recent study in the journal Reproductive Biology and Endocrinology, carried out on males aged between 27 and 67, showed that using a D Aspartic Acid supplement resulted in an average increase of 45.5%.

Because of its effect on increasing test levels in the body, the benefits of supplementing with D-Aspartic Acid are numerous. Elevated levels in males are associated with:

  • Increased strength and power

  • Faster muscle gains

  • Improved muscle to fat ratio

  • Increased energy and endurance

  • Faster recovery from exercise

  • Improved mood

  • Improved drive and focus

  • Reduced cortisol, leading to lower stress levels

  • Improved libido

High male hormone levels are often referred to as the ‘holy grail’ of bodybuilding and athletic performance. With the above benefits you can see why. What makes DAA an even more exciting supplement, is that it is totally natural and extremely cost-effective. Our pure D Aspartic Acid powder starts from less than £0.18 (18p!) per serving, making it the best value D-Aspartic Acid powder in Europe!

D Aspartic Acid Ingredients

100% D-Aspartic Acid.

Nutrition per 3g Serving per 100g
D Aspartic Acid 3g 100g

Suitable For

Vegetarians & Vegans




Mix 1 slightly heaped scoop (approximately 3g) with 50ml water, either in the morning or before bed.

We suggest using D-Aspartic Acid powder for 4-8 weeks at a time, then discontinuing use for 4-8 weeks before commencing another cycle. This will prevent your body from becoming too acclimatised to D-Aspartic Acid and ensure optimal results.


D-Aspartic Acid works effectively on its own as a natural hormone booster, however it also works effectively with other supplements such as Bulbine Natalensis and OptiZinc Tablets.

Customer Reviews

Good Value
I have heard about this acid a long time and decided to give it a go.
The taste is not horrible, yet far from delicious. I'd give it smth 4 out of 10.
However, I did come across a mixing issue. Does anyone knows any tricks to make this thing dissolved completely in the water? Otherwise it is like drinking water with sand in it. 80% dissolves quite well, but the remaining 20% is just small rocks. Anyone? On 17/02/2015 Maksim said...
Yeah, This does the trick.
Getting on for 38 now, so my T levels have obviously dropped significantly. So I thought at a shade under 7 nougats I'd give it a go.

Its tastes a bit like fresh orange juice, but without the orange taste (best way I could put it really) so its not totally un-palatable. A bit sharp, but I don't mind that at all.

1 Month in and I'm pleased to report I have zits, plump dangly nads, good morning wood, Raging inappropriate horn and more focus. Much like a teenager! So its a big thumbs up from me.

Forget trib, longjack etc. This has shown me that not everything is a placebo. Well worth the spend! On 15/02/2015 Steve said...
Please don't buy to increase muscle size, 45% increase in test is simply no where near enough to do so. However, what it does do is send levels of having the horn through the roof! Taste is pretty sharp but just neck it and get it down. For 8 quid, can't go wrong.
On 19/01/2015 Richard said...
Hell yes
Results results results.

Cycle it!

Enhance with zma. On 20/10/2014 Miki said...
Good value
Have tried tribulus, fenugreek, zma, and so many. Listen for the price, you can't go wrong, especially if you're over 30. This allows your body to produce much test.The effects are really noticable. Don't imagine how it will work with Bulbine, another great product. On 05/05/2014 hitachi7 said...
Definitely does something
I've used DAA a few times and it definitely does work in the sense that it increases sex drive, improved sleep and morning glory however I don't know if the increase in testosterone is enough to help muscle building.

Certainly a good, cheap thing to have in your diet/supplement regimen. On 11/04/2014 Philip said...
Fantastic stuff
This stuff works a treat, whilst on a cycle it's good to drink throughout to keep the pituitary gland working in conjunction with your testies. Whilst on PCT it's fantastic along side HCG and Clom**. If not on cycle this stuff is unreal mixed with Complete Pre Workout Advanced and Creatine Ethyl Ester Malate. The 500g bag lasts a long time when drunk every day. Great boosts in test levels, energy levels and recovery. Well worth the money. On 24/02/2014 Garry said...
Not bad taste, quite grainy though
Ok, so it's only my first time using this product, but I thought I'd throw up a review straight away.

Taste wise, when you read the word acid in the name you kind of expect it to be sour, and so it is. Not so much that it blows your face off, but if you imagine fresh lemon then you won't be too far off.

For the size of the portion (with only 50ml water) it doesn't mix too well though, ends up quite grainy at the end (much to the amusement of my colleagues as I slugged the last of it).

Time will tell if the product works as stated, but as I have had several products from BulkPowders now, I can certainly vouch for their general product quality. On 08/01/2014 Gavin said...
Nice dreams
Taking it before bed makes me dream more and boosts my morning mood and throughout the day.
On 31/10/2013 Nicolai said...
Seems to work
Definitely does something as I do see gains in strength when using this, but it doesn't last, so I normally cycle it. It increases sex drive no doubt about that On 04/09/2013 jj said...
Good stuff.
Used this stuff quite a few times and at very least it boosts libido.

If you want to get the best from it use an AI with it. On 08/08/2013 Jamie said...
D Aspartic Acid is a great product and really recommend it if you're getting on a bit especially in the sack. But this one is very grainy for my taste. Needs to be finer in texture especially since it does not taste nice. I down it straight in one and get particles left over. On 06/07/2013 Paul said...
Well worth trying for older men...
I am 44 and it took a few weeks for this to kick in - like other reviewers though, I am sure that it has had a positive effect. Libido, lean muscle mass both up, belly fat down. It does taste pretty rough - I dump a spoonful in apple juice and down it in one before breakfast.

Much better than Tribulus and the other test boosters IMO. A 100g pouch lasts roughly 4 weeks, which is one cycle - 4 weeks on, 4 weeks off. I have already bought another lot to start the next cycle in July.

I take this along with krill oil + super strength omega 3's (which I take at breakfast, lunch & dinner), which I am convinced have also contributed to my fat loss. If you are an older bloke (40+) and want to improve the impact of cardio and weight training, I would definitely recommend D-Aspartic Acid and the fish oils. I work out 2 or 3 times per week, run/ cycle at weekends.

Brilliant stuff. Cheap too :-) On 07/06/2013 Steve LBMK said...
Very sour taste for a libido boost
It's hard to quantify the effects of a product like this as it is often combined with other supplements. None the less I would say the results are tangible as I definitely felt a boost in my libido when I started taking it.

As far as taste goes, this will really ruin even the nicest tasting of protein shakes if you chose to mix it in! It has an unbelievably sour taste that makes not breathing through your nose a necessity. A solution I have found it to mix it with a bit of Cola in a glass and then it just tastes like a shot of a sherbet. Alternatively put it in capsules. On 01/06/2013 Alex said...
Great Results
This products certainly works for me - after about 10 days libido was noticeably increased but my strength gains were brilliant.

I put 10KG on my bench & deadlift and noticeable improvements on free weights routines. I cycle on and off every 4 weeks or so but the strength gains whilst off it have remained.

Used in conjunction with Complete Preworkout, Complete All In One & Complete Lean Mass. On 19/03/2013 Ashy said...
The Real Deal
-Definite test increase, one that was pinpoint-able and absolutely there 100% for sure this time.
-Definite results, I put 20lbs on my squat and 10 on my bench in a month, I think that is cool.
-Body fat decreased, visible especially in my man-gut.
-Traps seemed to be primary benefactor, they pop'd up, but this has to be a result of training and nutrition as well, it's just what I noticed most.

I waited 7 days to review to see if I felt weird or anything afterwards. not a scientifically determined time length I know. I continued everything I had been doing while on this. I don't feel anything shrinking and I am sleeping well, not crying randomly or other non-masculine characteristics, so I think everything is all good. On 07/02/2013 Dennybhoy1888 said...
It Works......
Defo works, strength gain noticeable after about 10 days for me and way more psyched during workouts, Definately worth a try... I've cycled off it for the last 4 weeks and now im started on 'T-Surge' since yesterday.. I will note the difference, if any, on T-Surge reviews on the website.... Thanks again BP On 16/09/2012 Paul-D :) said...
This product works well. You will see a difference in about 4 days.

The change you will see are changes in emotions and during intense sessions you will feel more power and more urge to train harder. Slightly like how synthetic test would change your moods, however I find when natty test is up emotions are even more unstable than synth.

The effects of this will not really be seen on your circuit type of trainer, more the guys who get dirty with the iron.

This is def an amazing add to your pct and will throw out the need for HCG.

I would also do some good reading on this product to asses if you should add this to your supps has pos and neg effects!

Great product but only for elder guys!
Hello, this is a really good product for guys above their twenties. Younger guys with, as we all know, high natural levels should not mess with their system. If you are under 20 and have low levels or you think you have, then go to your doctor to check it out!

On 27/05/2012 MP said...
great product!!
i have a low testosterone level and it helps a lot with my problems with my libido... and i can see it on my blood tests of testosterone levels.. On 11/04/2012 Anonymous said...
Jury still out
Having just finished the first 4 weeks on the product and now cycling off for 4 I have to say the jury is still out. If there is any effect it is minor and subtle. I wasn't expecting miracles as only a 40% test boost has been reported in tests. I will be keeping a close eye on things in the off cycle before another 4 weeks on.
Very difficult to give a star rating on that basis. Benefit of the doubt: 3.
W.r.t. to a previous review, why on earth is a 19 year old using a natural test booster when at 19 natural test is through the roof anyway?? Really can't see the point in using the product until you are least over 25 years of age.
Taste - like soluble aspirin On 11/04/2012 Anonymous said...
Tip for mixing
Mix with half the weight of baking soda and mix/shake. On 11/04/2012 Anonymous said...
