    Energy through the roof easy to take in short if you don't have some get some (Posted on 12/12/2017)
    Great value, quick and effective! Review by Skinny Seaghan
    I'm a 25yo self confessed hard gainer. I take this just before I go to bed (I'm on my 3rd bag) to boost energy, recovery and sleep. I cycle it with 3 weeks on, 1.5 weeks off, and a 2 week complete break every so often so you don't become dependent on it for producing testosterone, and find it to be super effective. There's an easily noticeable increase in testosterone levels (required for muscle gain without resorting to steroids)..... and even as a young lad it's noticeable in the bedroom too! (Posted on 11/12/2017)

    Great Supplement Review by Kerrylal
    This BP DAA is truly top class! Having twice a day really supports my natural test productions, compliments my other pre workout n bedtime supps and I can feel the effects! Highly recommend! (Posted on 02/12/2017)
    Definitely works Review by A.D
    After 2 months of constantly feeling fatigued, lethargic, and suffering from slow recovery I decided to try this. And boom! Everything went back to normal within 2 weeks. Not only I got my strength and energy back, but I also started hitting pr's again. I used this for the performance in the weights room and have no idea about the bedroom :)

    I just turned 22 so ignore the guys who say you have to be over 30. Don't hesitate to give it a try. It's cheap and the smallest size lasts about 6 weeks. (Posted on 17/07/2017)
    amazing Review by leeo
    Everything bulk powders sell is brilliant but this is top of my list. Have tried alot of other products that had no effect felt huge difference after two days on this, I'm over 30 now and my body was sluggish and weak, no energy to use the gym and in general felt shit in myself since starting this I feel brilliant back in the gym doing workouts I couldn't do since I was 20 I will definitely be buying again and highly recommended to anyone who feels their testosterone is on the low side, the taste doesn't bother me (Posted on 24/05/2017)
    Seems good! Review by smithma01
    Bought this along with protein and pre-workouts - the powder has a slightly bitter taste and is best mixed with pre-work out or taken in just water. I have mixed this with protein (banana, choc cookie and peaches and cream) and its not unpleasant but tastes better in apple and lime pre-workout! (Posted on 17/02/2017)
    Impressed Review by English Steve
    Very Impressed

    Thought I would try this and boy am I glad I did.

    been a little low on everything from the work home and gym but been on this for about 2 weeks now
    and I back in the fold

    Seems to work for me (Posted on 06/02/2017)
    Prepare your taste buds. Review by Manimal
    As a middle aged guy I thought I'd try d'aspartic acid as the wife has been complaining of my lack of action under the sheets. Well after a couple of weeks of taking which could only be described as drinking sour grit, my libido has gone through the roof ,now she ain't complaining.
    Strength is slightly increased but have noticed my mood feels elevated. Overall great product for the money will definitely buy again. (Posted on 15/11/2016)
    Great Product Review by midle_aged_andy
    Originally starting using DAA to help me train. burn fat and help with muscle growth..but with the higher testerone levels came a welcome side effect...just ask the wife (Posted on 08/06/2016)
    d aspartic acid Review by rab mulholland
    i feel stronger on this defo works on me (Posted on 08/05/2016)
    50ML!! Review by G
    Very good product. Noticable difference after as little as a couple of days. Tastes acidic (who would of guessed?) there is the issue of globules forming HOWEVER it does say take with 50ml of water. That is a shot glass worth. NOT an entire glass full. 50ml water + the scoop mix and drink straight away and that solves the issue. Cycle it 3 weeks on 3 weeks off. (Posted on 05/03/2016)
    aka Miracle Grow Review by Ross
    Was a bit sceptical about this at first but for less than £8 It was worth a bash.

    at first I was drinking mixed in water and it wasn't great, a very bitter and hard to disguise. However, I started to mix it in with my protein shake and added a small amount of dextrose in to take the edge off, overall it was a 'better' mix and was drinkable, (I was taking this twice daily so it couldn't have been that bad!)

    After a week I was like a machine! My strength had gone up, my weight had rocketed, and my sex drive was insane (maybe too much so bare that in mind). Definitely noticed a growth in testicle size and 'productivity'. Overall test levels had gone up a lot, started getting the random long hairs, spots on my back, oily skin, spots, very much like going through a second puberty. wouldn't say this is a downfall as now i know I need to combat these side effects next time.

    I was taking Creatine mono, pure whey, and eating relatively well through out this cycle, so no other test boosting supps. I cycled a month on and just coming to the end of my month off ready to go again, even on my 'off' month my gains still remained, sex drive has started to calm a little, but still high.

    amazing product if your looking to whack on a bit extra and boost test naturally. (Posted on 18/12/2015)
    Good product but... Review by Bren
    ...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. (Posted on 18/05/2015)
    Good Value Review by Maksim
    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? (Posted on 17/02/2015)
    Yeah, This does the trick. Review by Steve
    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! (Posted on 15/02/2015)
    D-AA Review by Richard
    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.

    Hell yes Review by Miki

    Good value Review by hitachi7
    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. (Posted on 05/05/2014)
    Definitely does something Review by Philip
    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. (Posted on 11/04/2014)
    Fantastic stuff Review by Garry
    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. 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. (Posted on 24/02/2014)
    Not bad taste, quite grainy though Review by Gavin
    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. (Posted on 08/01/2014)
    Nice dreams Review by Nicolai
    Taking it before bed makes me dream more and boosts my morning mood and throughout the day.

    Seems to work Review by jj
    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 (Posted on 04/09/2013)
    Good stuff. Review by Jamie
    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. (Posted on 08/08/2013)
    Grainy Review by Paul
    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. (Posted on 06/07/2013)
    Well worth trying for older men... Review by Steve LBMK
    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 :-) (Posted on 07/06/2013)
    Very sour taste for a libido boost Review by Alex
    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. (Posted on 01/06/2013)
    Great Results Review by Ashy
    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. (Posted on 19/03/2013)
    The Real Deal Review by Dennybhoy1888
    -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. (Posted on 07/02/2013)
    It Works...... Review by Paul-D :)
    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 (Posted on 16/09/2012)
    Works Review by Sean
    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! Review by MP
    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!

    Jury still out Review by Anonymous
    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 (Posted on 11/04/2012)
