Ashwagandha and Testosterone: Does It Work?

Ashwagandha is one of the most studied adaptogens for male hormone support. The KSM-66 extract, in particular, has solid human data.

What the Studies Show

Multiple RCTs report increases in testosterone, LH, and sperm parameters in men taking 600mg/day of KSM-66 ashwagandha for 8–16 weeks. The effect is more pronounced in stressed or subfertile men—which describes a lot of guys coming off cycles.

Mechanism

Ashwagandha appears to support the HPTA and reduce cortisol. Chronic stress suppresses LH and testosterone. By modulating stress response, ashwagandha may create a better environment for recovery.

Dosing for Recovery

600mg/day of KSM-66 is the dose used in most positive studies. Our stack uses this dose. Avoid mega-dosing—more isn't necessarily better.

Bottom Line

Ashwagandha won't magically fix suppression, but it's a useful addition to a recovery stack—especially for guys dealing with stress, poor sleep, or suboptimal baseline hormones.
