No significant negative interactions. Metformin may improve metabolic parameters that complement testosterone replacement therapy, particularly in men with metabolic syndrome or insulin resistance. Some evidence suggests metformin may modestly reduce testosterone levels in men, though this effect is clinically insignificant in the context of exogenous testosterone use.
