For a long time, I was searching for effective methods on how to increase testosterone levels naturally, without using steroids. Recently, I came across Tim Ferriss’s book “The 4-Hour Body,” where the author described his plan developed over many months. It is probably the most optimal way to raise testosterone levels without the harmful effects of anabolic steroids.

Benefits of Higher Testosterone Levels
An increase in testosterone levels can bring numerous benefits, such as building muscle mass, sculpting a chiseled physique, and enhancing sexual performance. These three elements are among the most sought-after results for individuals interested in learning how to naturally boost testosterone levels. Testosterone is the primary male sex hormone, playing a pivotal role in muscle mass development and maintaining optimal physical fitness. Many athletes, particularly those competing in physique contests, employ various methods to elevate their natural testosterone levels. Higher testosterone levels can also improve libido and overall sexual performance. However, it is crucial to remember that excessive testosterone concentrations can adversely impact one’s health and should be monitored regularly.
Tim Ferriss Method Results

The author long pondered how to increase testosterone levels safely and effectively. He approached this issue with a highly scientific mindset, closely monitoring his health throughout the entire transformation process and the development of the perfect plan. Spoiler alert: he managed to increase his testosterone level from 244.8 to 653.3 ng/dL. Later, he even reached 835 after adding Brazilian nuts to his diet! This increase amounts to 3-4 times the original level! Additionally, Ferriss more than doubled his free testosterone level and halved his estrogen levels.
Tim now employs two protocols that he believes are most effective in increasing testosterone levels. He developed these based on multiple, repeatable blood test results.
The first of these protocols aims to maintain high testosterone levels and overall well-being in the long term. The second protocol is designed for pleasure – a short-term “booster” that enhances libido and bedroom performance. In the following section, we will take a closer look at both of these protocols.

Protocol #1: Long-term and sustainable testosterone level increase
Fermented cod liver oil
2 capsules upon waking and before sleep – e.g., Green Pasture Blue Ice Fermented Cod Liver Oil
Vitamin D3
3,000-5,000 IU upon waking and before sleep (6,000-10,000 IU daily) until you reach a blood level of 55 ng/mL. You can test your vitamin D level at home with simple plate tests, such as this one. However, a lab test will be more accurate. If you spend a lot of time in the sun, your vitamin D level is likely to be higher, and you can use smaller doses. Example offer:
Short (10-minute) baths or showers with cold water
Upon waking and just before sleep. Gradually decrease the water temperature and start pouring cold water on your limbs, then your body and head.
Brazil nuts
3 whole nuts upon waking, 3 whole nuts before sleep. It is important to choose nuts from Brazil and not other countries. These contain the most selenium, which is essential in the process of raising testosterone levels. This type of nut has the highest amounts of selenium among all available foods – 96 µg/100g! 3 nuts weigh about 16g and contain 15µg of selenium. Example verified offer:

Protocol #2: Short-term testosterone boost, “nitro protocol”
If you’re wondering how to increase testosterone levels in order to improve your bedroom performance, you should apply these rules about 20-24 hours before intercourse 🙂
Ferriss recommends consuming at least 800 milligrams of cholesterol three hours before bedtime. This means the night before your planned passionate night with lots of sex ;). It’s important to get the good cholesterol, so going to McDonald’s is out of the question. A good source of healthy cholesterol is eggs, with about 4 whole eggs containing 800mg of this compound. What’s the point of doing this? It’s simple, testosterone is made from cholesterol, which is mainly produced during sleep!
Additionally, four hours before sex, eat:
4 whole Brazil nuts (about 20g) LINK
20 raw almonds (you can get them at your local store like Walmart or Lidl or buy them wholesale online) LINK
2 capsules of Blue Ice Butter Oil / Fermented Cod Liver Oil Blend LINK
Vitamin D LINK
Adequate levels of vitamin D allow for raising low testosterone levels. It is essential in the processes that take place in our body during its production. This has been proven, among others, in this study https://pubmed.ncbi.nlm.nih.gov/21154195/
Summary: How to Increase Testosterone Levels Naturally with Key Steps
In conclusion, understanding how to naturally increase testosterone levels is crucial for anyone seeking improved muscle growth, a sculpted physique, and enhanced sexual performance. By following Tim Ferriss’s two protocols, focusing on a proper diet and supplementation, and maintaining optimal vitamin D levels, you can safely and effectively boost your testosterone without resorting to harmful anabolic steroids. Remember to regularly monitor your hormone levels to ensure a balanced approach to your health and well-being. By incorporating these tips, you’ll be well on your way to achieving your goals and reaping the benefits of higher testosterone levels.
