A study by a team at the University of Southern California, Los Angeles (https://doi.org/10.5534/wjmh.190043) found no data for 67 of the 109 supplements on the market. Only 14 of the remaining 42 had consistent data on increasing blood testosterone. in my research, only four of them had small-group human clinical trial data. It was Eurycoma longifolia extract, Fenugreek extract, Magnesium, Shilajit.

Eurycoma longifolia extract (Tongkat ali extract) has undergone multiple clinical trials using Physta from Biotropics. Volunteers took 100 to 600 mg/day for 2 weeks to 3 months, but the results were mixed. Fenugreek extract has been clinically tested in women to improve perimenopausal discomfort and hormonal balance. The results of this clinical trial have been reported as paid papers, so the details are not known for me, but it is said that taking 250 mg twice a day for 46 days increased free testosterone by about 40% and improved symptoms. Magnesium has also shown in clinical trials that 10 mg/kg of magnesium intake once daily increases free and total testosterone levels in sedentary individuals and athletes. It is said that the increase rate is higher in those who exercise than in those who are sedentary. This is also reported as a paid paper, so I don’t know the details too. Shilajit was examined for its effects on androgenic hormones in men. Treatment with 250 mg twice daily for 90 consecutive days was found to significantly (P < 0.05) increase total testosterone, free testosterone, and dehydroepiandrosterone (DHEAS) compared to placebo.  This is also reported as a paid paper, so I don’t know the details too.

The reason I’m only talking about human clinical trial data here is because this study is the most reliable. Less than 30% of the drugs that are effective in mouse trials are effective in humans. In addition, even if it is effective in tests using cultured cells, it will probably be less than 3% effective in humans. A pharmaceutical company collects data from more than 100 people in a double-blind comparative study in order to apply to the authorities. On the other hand, it costs a lot of money to conduct clinical trials, so most of the good supplements cannot be tested. In the case of supplements, there are many that have not been clinically tested, so the idea is to test them on your own body. Get rid of supplements that don’t work.

As I mentioned in the previous article, high testosterone levels in the blood tend to lead to a longer life, and hormone replacement therapy(TRT) after age 60 improves muscle strength. I would like to try it to see if it fits to me. Note that the above study reports are for men.
