    • DAA Doesn't Work



      by Will Brink Brinkzone

      In the video below, I discuss the popular “Testosterone booster” supplement D-Aspartic Acid (DAA) and update my opinions of this general category of supplements.

      Study mentioned in the vid:

      D-Aspartic acid supplementation combined with 28 days of heavy resistance training has no effect on body composition, muscle strength, and serum hormones associated with the hypothalamo-pituitary-gonadal axis in resistance-trained men

      Department of Health, Exercise and Biochemical Nutrition Lab, Human Performance, and Recreation, Baylor University, Waco, TX, USA

      Abstract

      It was hypothesized that d-aspartic acid (D-ASP) supplementation would not increase endogenous testosterone levels or improve muscular performance associated with resistance training. Therefore, body composition, muscle strength, and serum hormone levels associated with the hypothalamo-pituitary-gonadal axis were studied after 28 days of resistance training and D-ASP supplementation. Resistance-trained men resistance trained 4 times/wk for 28 days while orally ingesting either 3 g of placebo or 3 g of D-ASP.

      Data were analyzed with 2 × 2 analysis of variance (P < .05). Before and after resistance training and supplementation, body composition and muscle strength, serum gonadal hormones, and serum D-ASP and d-aspartate oxidase (DDO) were determined. Body composition and muscle strength were significantly increased in both groups in response to resistance training (P < .05) but not different from one another (P > .05). Total and free testosterone, luteinizing hormone, gonadotropin-releasing hormone, and estradiol were unchanged with resistance training and D-ASP supplementation (P > .05).

      For serum D-ASP and DDO, D-ASP resulted in a slight increase compared with baseline levels (P > .05). For the D-ASP group, the levels of serum DDO were significantly increased compared with placebo (P < .05). [B]The gonadal hormones were unaffected by 28 days of D-ASP supplementation and not associated with the observed increases in muscle strength and mass.

      Therefore, at the dose provided, D-ASP supplementation is ineffective in up-regulating the activity of the hypothalamo-pituitary-gonadal axis and has no anabolic or ergogenic effects in skeletal muscle.

        I wish we could get a study on individuals post cycle when natural test levels are trying to recover. Wishful thinking I'm sure. Maybe test on elderly men with low test levels idk. Does daa improve recovery or will you recover just as quick without? I always add daa to pct but if more info like this comes out I may just save my money.

        Already been researched showing it raises lh. Still going to be in future pcts for me. Most of the studies done on it not working was in people who had healthy test levels already.

        Kind of figured this would start being the case with additional research coming out. It was terrible for me and actually lowered test levels. Come to find out, this is actually more common than anyone lets on. Just don't ever say anything bad about DAA or you may as well be picking a fight with the people that still take it.

        I'll again be honest in saying DAA has never done a thing for me. Now as for PCT... I may still take it but lets be honest, while taking a SERM how much can you really accredit DAA? Are you ever running it solo during PCT? Never

        I may leave it out of PCT completely next time. Straight SERM along with supps that help with appetite, prolactin, est rebound and all that stuff. But, DAA did not impress me, ever.

        I'm sure it helps someone because many still use it. Including me by default

        Activate Xtreme/Triazole is the only natty run I have ever done (so far, on day 3 of Tropinol XP) that I could 100% without a doubt notice an increase in strength. Out of about 15 different products. DS has bloods I think though so... not sure what to think.

        I think that the only reason this is news is because there were so many articles stating how great it was. Then we started using it and many found out it wasn't true. But, why is that a surprise at all? When you deal with OTC, you already know that it is always a chance and that everyone responds differently. To me, I chalk it up to every other OTC....except Agmatine. lol

        Agreed, man! Agmatine is soo cheap too. It's my #2 for value next to Creatine.

        nope does not work, I had bw before and during, total and free test went down,did not test lh wish I would have, and if it did bump lh I do not think it would be significant enough to make a difference in atheletics

        I find it interesting that most of the people that say how well it works never actually get blood work, they just base it on their workouts. Those of us that know it doesn't work for us, actually do get bw to prove it. Secondly, why is it that it lowers total and free test levels? I would think that it should either stay even or not be an amount that is of note.

        Another side effect I always got and just powered through with the belief that it was working, was almost blinding headaches. It would be at the back of my head behind my ears and last about an hour after each dose.

        What about the morning wood? DAA and mucuna prurien seems to do it. Thought that meant more free test floating around.

        Libido and test levels don't have the correlation one might think.

        I hear you ya, yeah I think most people go by the feel,i have gotten increased libido from it but I was also taking maca and long jack with it,i have taken 3-4 times to give it a good try but I have never gotten any improvements from it,as far as my test going down I cant say that the daa caused that as I went from 251 to 218 which is with in a normal fluctuation, I mainly mentioned that just to show that it definitely did not work,but if someone is like me and has crappy levels and you do get a small bump in levels you still have crappy levels, I think a lot of people take it with an otc anti e and my opinion is the anti e is working much more than the daa.

        Always use it in PCT with trib, DHEA and ZMA. Keeps the test levels up for me.

        Morning wood ain't libido, bro. It's nature at work. Does someone want to comment on why this happens with DAA?
