What are the benefits of testosterone supplementation?

Testosterone supplementation may help improve testosterone-related symptoms and support sexual function, mood, body composition, muscle mass, and cognitive function—but the effects depend on the person and the reason for using it.

1. Effects and appropriate doses: Benefits and dosing vary with a person’s natural testosterone levels, individual response, and goals. Effects may be more noticeable when testosterone is low; treatment decisions should be based on symptoms and monitored with medical guidance. 1 2

2. Fertility effects: Exogenous testosterone can sharply reduce sperm production. HCG, FSH, or both may help offset this, but anyone concerned about fertility should discuss options with a clinician. 3

3. Lifestyle and supplements: Adequate sleep and sustainable exercise can support hormone health; vigorous exercise should not routinely extend beyond an hour. Tongkat Ali may increase free testosterone, while Fadogia agrestis may increase LH and testosterone, though long-term safety evidence is limited. 4 5 6

4. Creatine: Creatine may slightly raise total testosterone and increase DHT. The evidence does not establish that it causes hair loss for everyone; susceptibility may vary. 7 8
