Doctors treating patients with low testosterone often prescribe a therapy to increase testosterone levels. Both of these drugs are selective estrogen receptor modulators (SERMs), which increase testosterone production by blocking estrogen receptors in the hypothalamus. You can also take certain prescription medications designed to increase your testosterone levels through various mechanisms of action. The Genius brand focuses more on cognition and sports performance than sexual health, with numerous nootropics and workout supplements in its lineup. The maca increase brought it more in line with research into positive erectile performance studies, while the decrease in D3, though significant, still offers enough to help men who aren’t quite clinically deficient to stay up on their D levels. Regular T-Drive is a fine supplement, with good doses of ashwagandha, fenugreek, boron, D3, and zinc. This time, however, the differences among them are frustratingly nuanced. Like Jym, Innosups offers multiple versions of its T-Drive supplement, with regular, Magnum, and Apex available. What’s more, for ongoing users, it doubles the cost of the product. Our editors are fans of Jym in some cases; the company has consistently been included in our guide to the best muscle-building stacks. Nugenix offers several testosterone boosters, and Total-T Maxx is its most expensive at $169/month. One found that sprinters seem to get an advantage from testosterone, while other runners didn’t. Some studies have even found mixed or opposing results within their own findings. In severe cases they have female external genitalia, though also internal testes, though in more mild cases the genitalia can be mixed. These people mostly develop and live life as women, often not even realizing they have the male XY chromosome pattern. But some people are born with mutations in their androgen receptors that makes them non-functional, so even though they’re producing testosterone it can’t actually affect anything. It seems to follow logically, then, that testosterone would boost your athletic ability generally. It’s also a driver of red blood cell count, and the more red blood cells you have the more oxygen you can carry to your muscles, increasing your aerobic capacity. Ingredients like Tesnor®, Ashwagandha, and Shilajit have clinical studies supporting their efficacy. Unlike many supplements with exaggerated claims, Test+ is grounded in research. By boosting both total and free testosterone, it ensures the hormone is readily available for critical physiological functions. This can lead to reduced energy, muscle loss, weight gain, low libido, and mood changes. For example, Tesnor® and Shilajit improve the efficiency of testosterone-producing cells in the testes, while Ashwagandha reduces cortisol (a stress hormone that suppresses testosterone). Testosterone is a foundation—not just for sexual function but for strength, stamina, and emotional grit. If you’re logging hours on the bike or pounding pavement weekly, don’t ignore your hormones. The goal is to avoid burnout while building a strong, energized, testosterone-optimized physique. This kind of hybrid week balances endurance gains with hormonal recovery. Your body controls the levels of testosterone in your blood. However, the majority of testosterone produced in the ovaries is converted to the primary female sex hormone, estradiol. "Anabolic" refers to muscle building, and "androgenic" refers to increased male sex characteristics. Levels of testosterone are naturally much higher in males. Your adrenal glands also produce the hormone dehydroepiandrosterone (DHEA), which your body transforms into testosterone and estrogen. If testosterone levels are too high or too low, it can cause certain symptoms. Testosterone levels are naturally much higher in males.
