Anti-Estrogen/Aromatase
These anti estrogen and testosterone boosting supplements support lean body mass, muscle growth and sex drive.* Products like TestroBoost and 6-OXO inhibit (block) the aromatase enzyme which converts testosterone to estrogen.* Testosterone is the most powerful natural anabolic, muscle-building hormone, but estrogen does not promote muscle growth or libido. So by minimizing the conversion of testosterone to estrogen, these supplements help promote more testosterone activity.
