    • Good product but...

      ...make sure you have a second glass of water at the ready. This stuff just does not dissolve and sticks in your mouth like bitter sand.

      That said, it worked well for me when combined with ZMA.

      Bren on 18/05/2015
    • 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?

      Maksim on 17/02/2015
    • 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!

    • D-AA

      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.

      Richard on 19/01/2015
    • Hell yes

      Results results results.

      Cycle it!

      Enhance with zma.

      Miki on 20/10/2014
    • 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.

    • 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.

      Philip on 11/04/2014
    • 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.

    • 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.

    • Nice dreams

      Taking it before bed makes me dream more and boosts my morning mood and throughout the day.

      Nicolai on 31/10/2013
    • 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

      jj on 04/09/2013
    • 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.

      Jamie on 08/08/2013
    • Grainy

      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.

      Paul on 06/07/2013
    • 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 :-)

      Steve LBMK on 07/06/2013
    • 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.

      Alex on 01/06/2013
    • 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.

      Ashy on 19/03/2013
    • 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.

      Dennybhoy1888 on 07/02/2013
    • 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

      Paul-D :) on 16/09/2012
    • Works

      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!
