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

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). 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.

In case any of you haven't noticed...Will Brink doesn't think ANY supplements work except for creatine mono
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

What about the morning wood? DAA and mucuna prurien seems to do it. Thought that meant more free test floating around.
Take it pct?
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.
Libido and test levels don't have the correlation one might think.
Well, it should happen normally, just as you mention. I am 39 and even with test levels of 200 before going on TRT, I can't think of a single morning in my life that I haven't woke up with morning wood. DAA has nothing to do with it.
Morning wood ain't libido, bro. It's nature at work. Does someone want to comment on why this happens with DAA?
This. I have morning wood during the start of a PCT. Test levels VERY low I'm sure.
I can take trib and get stronger morning wood, bro. Won't do sh*t for test levels. Not for me anyway... if anyone gets raised test from trib, speak now... but that boat sank a long time ago. Don't think you should compare chubbies to test levels. Compare blood results.
So this is going to be TMI for sure but the first night I took DAA a few years ago, I had a wet dream. It was the only one I have ever had. Notable also because I was 40 years old at the time. So I do believe it has some effect on t levels or at the very least some hormonal function.

Just saying, you shouldn't compare chubbies to test levels. Blood results are the only way.
If it does not raise test, why does DAA make me so strong every time I use it? Is it because I am 46?
Seems to be the only product I have found where I can put on what amounts to a pound or two of solid muscle each run.
High test doesn't equate to strength and even the amount that it would raise it is negligible anyway.

So why do I take it and notice a huge strength increase?
Lol it's actually not normal to have morning wood every single day

Crap I just ordered some t-x3. Fingers crossed. I hate waisting $
Sadly, his comment was probably based on a locker room study of about 3 of his bros. They should really warn people that join this forum, ignorant broscientific pretend-facts will not be viewed as fact, even if you DO have 2 years of highschool weight-training classes under your belt....I won't get into a stupid conversation like this based on what you determine as normal.
cuz youre gullible as f*k?
theres a whole lot of stoopid coming out because of this article

no disrespect as this is my opinion, but I would say placebo effect, is there anything else you change when you start daa? diet? training routine? more intensity in gym? if you do have crappy test levels say at 200 even if you get a 50% elevation your still at 300, but I don't think you are going to get an elevation in levels anywhere close to that.
I took dpol last year for 4 weeks. I did gain 1 lb a week. I did not notice any thing else good or bad
