Unpacking the ideal testosterone dose: its benefits, risks, and the need for personalization.
Testosterone–a word that resonates far beyond the confines of biology classrooms. It's an essential hormone, playing many roles in the human body, from muscle development to mood modulation. Every human carries testosterone, a cornerstone of our biological makeup. While its presence is universal, its levels vary. Many ask: Is there a “Goldilocks” zone, a perfect range?
Thanks to a revealing podcast chat between Joe Rogan and Kurt Angle, we get a glimpse into personal experiences. "I take half a shot of test a week just to keep my testosterone at the right level," shared Rogan, which Angle echoed; they then proceeded to highlight the benefits of maintaining levels between 600 and 800 ng/dL. These revelations piqued our curiosity. Is there a science-backed sweet spot for testosterone? 
Testosterone Levels: The Basics
At its core, testosterone is a steroid hormone, predominantly produced in the testes of males and, to a lesser extent, in the ovaries of females. It's the linchpin in the intricate machinery of the human body. From influencing the deep timbre in a man's voice during adolescence to fostering muscle growth and even playing a role in hair patterns, testosterone's impact is broad and significant.
But why the fuss about its levels? Imagine a car running with too little oil or an excess of it; neither scenario is ideal. Similarly, with testosterone, it's all about striking the right balance. Too low, and one might experience fatigue, reduced bone mass, or even mood disturbances. Too high, and the risk of certain medical conditions can surge.
For young adults, the testosterone waters maintain a specific depth. Science indicates a "normal" range to be between 450 and 1,000 ng/dL. Though the spectrum seems broad, the average hovers around 650 ng/dL. This average, however, is not one-size-fits-all. Factors like age, lifestyle, and overall health play their part in determining individual optimal levels.  
The Evidence: Benefits of Maintaining Testosterone Levels
While testosterone's role in bodybuilding and masculine development is widely known, a deeper dive reveals multifaceted benefits, backed by rigorous scientific studies.
Our brain and testosterone share a more profound bond than one might initially assume, and a pivotal study published in 2006 shone a light on this connection. In this research, older men were administered varying testosterone doses of 50, 100, or 300 mg/week over a span of six weeks. The intriguing outcome? Only those on the intermediate dose showcased marked improvements in both verbal and spatial memory, hinting at a potential “sweet spot” in dosing. 
Bones, the pillars of our anatomy, are not immune to testosterone's influence, and another remarkable study ventured into this terrain. Here, older hypogonadal men underwent a 36-month treatment involving biweekly injections of 200 mg testosterone enanthate. "Hypogonadal" refers to a condition where the body doesn't produce enough sex hormones, typically resulting in low testosterone levels in men.
The results were eye-opening. Not only did they observe a surge in bone mineral density, but a staggering 10% enhancement was also seen in the lumbar spine, a critical region for overall back health. 
Muscle Strength and Mass
Muscle's relationship with testosterone is perhaps the most talked about, and scientific scrutiny validates this link. For example, in a study published in 2002, researchers gave treatments to older men, some with low testosterone and some with typical levels, to increase their testosterone from about 300 to 600 ng/dL over half a year. The result? Their leg strength greatly improved, with some showing as much as a 15-kilogram increase in their leg-lifting ability. Adding to this, a study published in 2005 found that when researchers gave older men with low testosterone levels shots of testosterone every two weeks for three years, their hand grip got significantly stronger.  
The testosterone tale is not without its cautions. Emphasizing the necessity of a balanced approach, a study published in 2005 unveiled some unsettling truths. Older men treated with substantial doses of 300 and 600 mg/week faced a high incidence of adverse effects. These can include retaining water, breast enlargement in men, worsening snoring or breathing issues during sleep, and increased red blood cells, with the biggest worry being about how testosterone might affect the prostate.
We know testosterone can speed up active prostate cancer, and many older men already have early signs of this cancer without knowing it. In fact, when looking at men over 60, almost half of them already have early-stage prostate cancer. However, the studies that have been conducted about this aren't imposing or long enough to be sure about the effects of testosterone on this cancer. 
Individual Variation and the Importance of Personalization
While Rogan and Angle's discussion on testosterone may have intrigued many, it's essential to remember that everyone's body is distinct. The way testosterone functions and is needed can vary drastically from one person to another.
Several factors come into play when considering our body's testosterone needs. Age, for instance, naturally impacts our testosterone levels, as they tend to decrease as we get older. Our genetic makeup can pre-determine how our body produces and reacts to this hormone. Lifestyle choices, whether it's our diet, exercise regimen, or habits like smoking and alcohol consumption, also play a significant role. Additionally, existing health conditions can either hamper or accelerate testosterone production.
Given all of these factors, it's dangerous to believe that a "one-size-fits-all" strategy would succeed. What is good for one person may be harmful to you. As such, seeking competent counsel and undergoing the appropriate tests to establish the best course of action for your unique needs is critical.
