If you’re a subscriber to my blog, you know I get a lot of questions about improving hormones – especially testosterone. This is because testosterone is the KING of all hormones for men.
- Increase muscle mass and strength
- Decrease fat, especially belly
- Improve libido and erection strength
- Enhance mood and happiness
- Improve cognition and memory
- On and on
And since there’s a decline in testosterone for men around the age of 25-27, especially in modern days, guys are looking for anything to help increase their testosterone, naturally.
I also wanted these benefits and that’s why over 20 years ago, I formulated one of the most potent and clinically tested testosterone boosters and hormone optimizing products on the market – called AlphaViril… which has a 20-year proven track record.
However, I’ve been asked many times about D-Aspartic Acid — does it work for boosting testosterone levels and why didn’t I include it in AlphaViril?
Today I’ll quickly discuss:
- What it is
- The results in men who exercise and those that don’t, including my own personal experience.
- The correct dose
- How to make it work better and improve results.
What Is D-Aspartic Acid
First, a quick background.
Almost every amino acid can occur in two different forms. For example, aspartic acid can be found as L-Aspartic acid or D-Aspartic acid. The forms have the same chemical formula, but their molecular structures are mirror images of each other.
L-Aspartic acid is produced in nature, including in your body, and used to build proteins. However, D-Aspartic acid isn’t used to build proteins. Instead, it plays a role in making and releasing hormones in the body.1-2
This includes the increase in testosterone production and release in the testicles.3
And thus, why many companies sell D-Aspartic acid as a testosterone booster. So far, so good.
My Personal Experience With It
When I found out about D-Aspartic acid years ago and it started getting popular, I decided to give it a try. Even though I’m a doctor, I’m still like everyone else. A new supplement comes out, I go give it a try and I experiment a lot with it.
And when it first came out, it was fairly expensive.
I tried 1 gram for a week and then 3 grams for a week and eventually 6 grams for a week. These were daily doses.
I think at the higher dose, I started to feel an increase in my sex drive, but it wasn’t by much. To me, higher sex drive and better erections is a quick test to see if the product is working at boosting my testosterone levels.
But after about a week or two, I felt nothing and my libido went down. Basically, around the 2-week mark, I felt the opposite happening.
I then took a break and gave it a try again a few months later and again, similar results.
However, in all honesty – I never did a hormone test to see if it worked at increasing my testosterone levels or not. I just did it by feel.
Clinical Studies & Results
So, let’s look at the clinical studies with D-Aspartic acid. Unfortunately, it’s all over the place with mixed results.
For example, in one 12 DAY study, 20 out of 23 men saw an average increase in testosterone by 24%.4 But the study didn’t give the dose used and it was with men who don’t exercise. It didn’t give age either. So for me, this is a poor study.
In another study that lasted 90 days, with men aged 37-43, who had sub-fertility and low sperm production, the D-Aspartic group experienced over a 30% increase in testosterone.5 This is good, but keep in mind this is NOT with guys who exercise and have normal fertility.
In fact, one study found NO increase in testosterone in men who performed weight training and took D-Aspartic acid for 28 days.6
What’s more, another study found that two weeks of taking a high-dose supplement of 6 grams per day actually decreased testosterone in young men who weight trained.7
Summary On Testosterone:
Based on the studies, D-Aspartic acid may increase testosterone levels in inactive men. However, it has NOT been shown to boost testosterone in men who weight train.
Weight Training Results
One assumes that an increase in testosterone, will also build more muscle and increase strength.
However, studies have shown that men performing weight training experienced no increases in testosterone, strength, or muscle mass when they took D-Aspartic acid supplements.8-10
One study found that when men took D-Aspartic acid and weight trained for 28 days, they experienced a 2.9-pound (1.3-kg) increase in lean mass. However, those in the placebo group experienced a similar increase of 3 pounds (1.4 kg) 8
What’s more, both groups experienced similar increases in muscle strength. Thus, the D-Aspartic acid didn’t work any better than the placebo in this study.
A longer, three-month study also found that men who exercised experienced the same increase in muscle mass and strength, regardless of whether they took D-Aspartic acid or a placebo.
Summary On Weight Training:
Bottom line is that D-Aspartic Acid does NOT appear to improve muscle size or strength gains.
Dosage And Results
Most studies and recommended dosages for D-Aspartic acid is 3 grams daily. That’s 3000 mgs.
Unfortunately, this appears to work in some men and not on others. Mainly, it works in people who do not exercise.
However, it does seem to help with sperm mobility and production. This is good for guys who are trying to have a baby and increase their fertility.5 This part it seems to have the most positive results and the dose is 3 grams for 90 days.
Also, if you do want to try D-Aspartic acid, use the POWDER form, not the pills. It’s much less expensive and here’s a product on Amazon for one that’s a good price – since they are all the same form.
The Problem With Testosterone Boosters
As I’ve stated in the past, you can’t simply increase your testosterone levels and expect it to stay that way. This is because your body has “checks and balances”.
For example, increasing testosterone levels is a good start – but you also, and more importantly, want to increase your FREE testosterone levels at the same time. This is done by lowering SHBG.
But with these supplements, your body quickly adapts and the testosterone boost is temporary and soon, it drops again.
Additionally, the older you are, the most the testosterone converts to “anti-testosterone” hormones – such as estrogen, prolactin, DHT, and adrenal and stress hormones.
Again, the end result is the temporary boost in testosterone, stops in about 2 weeks, your body adjusts and adapts and now, you have low testosterone again, but this time it’s even worse – HIGHER negative hormones.
Because my background is in endocrinology and hormones, I understand and know about all of this. This is why AlphaViril works so well – I’ve addressed all of these issues.
Thus, your testosterone goes higher and stays higher, while negative hormones go back down and thus, you have the levels of a youthful, young man at his prime. THAT’S the goal!
What Should I Take?
Anyway, if you want to give D-Aspartic acid a try, go ahead. My suggestion is to take 3 grams, about an hour before your workouts. Only about 3-4X weekly. This is enough to prevent adaptation and then see how you feel and look over the next few weeks and months.
Of course, I highly suggest you give AlphaViril a try if you haven’t already. It’s so effective it comes with a one year guarantee.
In fact, if it doesn’t help improve your hormones at the end of 30 days, you’ll get a full refund plus an additional $100.00 cashback on top of it.
I can make such a crazy guarantee because I have over 20+ years of proven clinical data and real feedback from thousands of users.
And no, I’m not trying to sell you a product – I’m just offering you a proven solution that has worked for thousands of men around the world, including myself – I’m the original reason I formulated AlphaViril – it was for me and I’ve continued to take it on and off for 2 decades.
