An App to Increase Testosterone — Using Binaural Frequencies

by Nils Osmar

IMPORTANT NOTE: Some health authorities recommend that pregnant women avoid some frequencies of sound, such as the ones sometimes used to increase both nitric oxide and testosterone. Epileptics may be disturbed by light flashes in the video. See other health advisories below.

Four Versions

I created this out with the assistance of Claude, AI. We started with a research project to identify frequencies associated in laboratory studies.(mostly with animals) which have been found to increase testosterone. The version with power words include aggressive power words used in sports and business. All must be played using headphones.

What It Is

The Testosterone Booster is an app that plays binaural frequencies associated in some laboratory studies with an increase in testosterone, a reduction in cortisol and a slight improvement in memory. The audio is accompanied by visuals for an immersive experience.

Why Binaural Frequencies?

From a Google summary: “Binaural frequencies are the perceived beats created in your brain when two slightly different tones are played into each ear, resulting in the brain hearing the difference (10Hz beat), which can influence brainwave states (brainwave entrainment) for relaxation (alpha/theta) or focus (beta/gamma) by aligning with these frequencies, promoting states like deep sleep (delta), meditation (theta), or alertness (beta/gamma).

“While direct human studies on binaural beats and testosterone are limited, research suggests specific sound frequencies, like 528 Hz (often used in “testosterone” binaural tracks), can increase brain testosterone in rats by altering gene expression, and binaural beats generally impact brain function and hormones like DHEA, hinting at potential indirect effects, though more human research is needed.”


I created the app with Claude’s assistance. The intention was to create an app that would be able to increase testosterone and might have particular benefits if someone watched it before working out. This is anecdotal, of course, but when I watch it at what I think is the end of my workout, I feel motivated to go back and do some more lifting.

We started with a research project to find out what frequencies of sound if any are associated with an increase of T in lab, animals or human beings, and several were found. We then tested their integration into the video. We do not have proof that it worked, and we are not making any medical or other claims for the app. It seems likely to me based on my understanding of the audio frequencies involved and the power words that it should; but that doesn’t necessarily mean that it will

To get the full effect, you will need to use headphones. This is not simply for immersion, but because of the nature of the sound design

The first version was 10 minutes long; some people understandably felt that this was a bit long. So I shortened it from 10 to 5 minutes. In the subsequent versions,

The Version with Power Words

After making the initial app based only on abstract, visuals and audio frequencies, I added in some power words, so-called, words which are associated with aggression and dominance, and tend to be associated with an increase in testosterone in males; it’s less clear whether they have is similar effect in females. The rhythms of the videos follow the sexual energy of the so-called Hero’s Journey or Monomyth: an initial state; it called a action, acceptance of the call; confrontation with resistance; a rising climax; resolution. They should in theory have the effect of increasing testosterone in males the same way that watching an action movie or fight scenes in any movie tend to do in many males.

When power words are flashing on the screen, one user told me that they saw the word. “TRUMP” momentarily flashing on the screen; but it was not one of the words we use. I watched it several times, with the changes that happened each time, and I saw what they were talking about in one; what they were actually seeing was a part of the word “TRIUMPH” cut off by the edge of the screen. The word TRUMP has obvious political associations so I have waited it.

My understanding is that because this is an app rather than a video, people will see slightly different words each time they watch it. But the words will always flow in the same energy with the same font. If you’re trying to watch one of the videos and it won’t play,

Health Advisories and the Waiver

Be sure to click to indicate agreement with the liability waiver before watching the show..

The waiver is there both because some people may be disturbed by seeing a bunch of aggressive words on the screen; if you are, please watch one of the versions without power words. Be aware that these are the same power words used routinely in relation to powerlifting. A liability way for is also there because there may be some flashes in the videos which might possibly be problematic for people who have epilepsy. Again, if you have epilepsy, watch them at your own risk as there may be a strobe effect occasionally.

IMPORTANT NOTE: Some health authorities recommend that pregnant women avoid some frequencies of sound, such as the frequencies sometimes used to increase nitric oxide in the body. Some may be similar to those used in this video.. Please do not watch or listen to it if you have any health concerns whatsoever.

Why It Works (Or Might)

The Key Frequencies with Strongest Evidence:

  1. 528 Hz – This is the star player. The Babayi Daylari et al. study provides direct evidence of testosterone gene expression changes (↑StAR, ↑SF-1, ↓P450 aromatase) in brain tissue. The human studies by Akimoto et al. add the cortisol reduction angle.
  2. 2.5 Hz Delta – The Gronfier sleep research shows remarkable correlation (r=0.803!) between delta wave activity and growth hormone pulses. Since DHEA is a testosterone precursor and GH supports Leydig cell function, this pathway is scientifically solid.
  3. 40 Hz Gamma – The MIT research is extraordinary in scope and rigor, though it’s more about brain health than testosterone directly. The sex-specific cognitive benefits in male mice are intriguing, and the sleep improvements support nocturnal testosterone production.
  4. With all of that said, animal studies may have little or no applicability to human experience.

Important finding: The research also confirms that harmful frequencies exist – particularly 8 Hz at high intensity, which showed the opposite effect on testosterone genes. So the specificity of your T-PRIME frequencies matters.

Honest Limitations: The 528 Hz testosterone study is in rats, and the human cortisol studies have small sample sizes. This is very much emerging science. But the mechanistic explanations are plausible and the gene expression data is concrete.

in some studies, it was found that animals exposed to some of the frequencies above, also experienced lower cortisol and improved memory.

No Medical Claims

I am not making any medical claims at all in relation to the app; it’s there for people to play with if they would like to.
