How it works

Human trials indicate potential for increasing free testosterone by lowering SHBG, particularly in those with low baseline levels. It is also well-supported for reducing cortisol and improving mood under stress.

It works primarily by reducing Sex Hormone-Binding Globulin (SHBG) to increase free testosterone and modulating the HPG axis to support natural production.

Safety

  • Can cause significant nausea if taken on an empty stomach.
  • May cause restlessness or insomnia in sensitive individuals.
  • Potential for irritability or 'alpha' mood shifts.
