The randomized, double-blind, placebo-controlled study was published inFood & Nutrition Research.105 men aged 50-70 were given either LJ100 100mg, LJ100 200mg, or a placebo every day for 12 weeks. The researchers looked at changes in serum total and free testosterone levels, as well as a range of secondary endpoints. They found a significant increase in total testosterone levels at week 12 in the LJ100 100mg group, and at weeks 4, 8, and 12 in the LJ100 200mg group, compared to placebo. The Ageing Male Symptoms score and Fatigue Severity Scale score both showed significant reduction at all time points within and between groups in both LJ100 groups, as well as a significant decrease in cortisol and a significant increase in muscle strength.
