    CalMagZinc supplements anyone?

    I take magnesium and zinc at night for sleep and they work. I feel I have more energy the next day as well. It thought it would be easier to take the two in one supplement.

    Zinc supplementation

    I notice a huge difference sexually when I start taking a 50mg of zinc supplement. Even from the first dose. But I'm left wondering if there is any negative effects while on TRT. Like does it raise DHT? or is it a common suggested supplement to take? Any thoughts, info? Thanks
