Is fadogia agrestis good for men to boost testosterone?

Potentially—but it’s not a well-established or risk-free testosterone booster. Fadogia agrestis may raise luteinizing hormone (LH), which stimulates testosterone production, but its long-term safety is uncertain. 1

• Mechanism: It may increase LH release and LH-receptor sensitivity, stimulating Leydig cells in the testes to produce more testosterone. 2
• Safety concern: Testicular-cell toxicity has been reported in rat studies at high doses; human safety evidence is limited, so use caution and don’t exceed recommended doses. 3
• Use and monitoring: One suggested regimen is three weeks on, one week off. Get bloodwork before starting and again after about four to eight weeks to check whether it’s helping and for unwanted effects. 4 5
