Longjack, also known as Tongkat ali and pasak bumi, is a shrub hailing from Southeast Asia purporting to improve libido. It’s gaining traction in the scientific community for potentially increasing testosterone levels, and researchers at South Africa’s University of the Western Cape found that longjack improved testosterone levels and muscular strength in physically active seniors (a population with typically low testosterone).
Testosterone fluctuates according to age and life circumstance, often plummeting at the onset of parenthood, and spiking (for some) during moments of triumph. Romantic relationships, too, can impact a person’s testosterone production; though the reasons are still not fully understood, entering a relationship tends to increase women’s testosterone levels, while decreasing men’s. Since males produce significantly more testosterone than females—about 20 times more each day—females can be more sensitive to these fluctuations. High levels of testosterone, particularly in men, have been correlated with a greater likelihood of getting divorced or engaging in extramarital affairs, though a causal link has not been established.

If you have a medical condition, including if you are pregnant or nursing, you should speak to your physician before taking a supplement. Consult a healthcare provider if you experience side effects.
Unlike women, who experience a rapid drop in hormone levels at menopause, men experience a more gradual decrease of testosterone levels over time. The older the man, the more likely he is to experience below-normal testosterone levels. Men with testosterone levels below 300 ng/dL may experience some degree of low T symptoms. Your doctor can conduct a blood test and recommend treatment if needed. They can discuss the potential benefits and risks of testosterone medication, as well.
There are three categories of healthy fat. Number one is healthy saturated fat. The truth about saturated fat is it’s actually good for you if it’s the proper kind. Healthy saturated fat is found in coconut oil and raw, fermented dairy products like goat milk kefir, yogurt, or raw goat or sheep milk cheese. However, avoid conventional dairy because it will actually damper your testosterone.
This causes your body to burn fat for the next 36 hours to replace your body’s vital energy stores. It addition to increasing your T-levels, it can help burn between 3–9 times more fat, lower your resting heart rate, lower blood pressure, keep your brain young by increasing circulation, and aids in detoxification by stimulating the lymphatic system.
The same study showed that drinking did, however, lower semen count and quality. And I want to remind you – this is an article  on improving testosterone levels, not general health as there are a lot of studies that show drinking leads to an assortment of health issues. This acute spike in Testosterone could be due to the effect alcohol has on libido, and also the energy influx in the liver?

Sprinting has been shown numerous times that it has positive effects on testosterone levels. One 2011 study (ref 84) looked at weightlifters who performed 4x35m sprints twice a week. In contrast to the control group (who continued lifting but did not sprint), it was found that “After the 4-week training program, total testosterone and the total testosterone/cortisol ratio increased significantly in the (sprinters) EXP group”.

Magnesium comes with a strict upper cap. Excess magnesium is hard on your kidneys, and can lead to kidney failure. The NIH recommends that men consume 400-420 mg of magnesium daily, but that they should not exceed 350 mg of supplemental magnesium per day. Because while it’s rare for people to chronically overdose on magnesium through diet (you’d have to eat a lot of almonds and spinach, for example), overdose by supplement is far more common.

Other Potential risks that can be caused by use of testosterone supplements are: People who take good testosterone supplements or any other kind of testosterone boosters can also experience many other side effects, including stomachache, problems with urination, dizziness, mood changes, intermittent breathing during sleep, changes in testicles, appetite loss, inflammation of gums, weight gain, nausea, painful erection, and protracted erection.
Although some men believe that taking testosterone medications may help them feel younger and more vigorous as they age, few rigorous studies have examined testosterone therapy in men who have healthy testosterone levels. And some small studies have revealed mixed results. For example, in one study healthy men who took testosterone medications increased muscle mass but didn't gain strength.
