Health Notes

Natural Testosterone Support

Natural Testosterone Support: Main Image
In men, testosterone levels peak in young adulthood and decline over time. A number of supplements are marketed as natural testosterone support, though these effects have not been demonstrated in clinical research. Talk to your doctor if you suspect your T levels are low.

Comments about GNC Pro Performance® Zinc Magnesium Aspartate:

If your goal is to achieve a deep sleep where the crazy dreams happen (and are very memorable) then this product will help you get there... every time you take it. It only works for me after a very light dinner, then I have to wait at least 4 hrs to be on an empty stomach, pop the pills, and off to dream land.

    Comments about GNC Pro Performance® Zinc Magnesium Aspartate:

    lowest quality ZMA you can get for the money. It is somewhat decent for sleep if you do not suffer from insomnia. However, it has a really low magnesium content and isn't nearly as relaxing as other ZMA options. Would not buy again.

    Solid product. I take 30 minutes before going to bed. Very restful sleep. Reduced muscle soreness. Only a couple drawbacks, the smell and taste are horrible and I do wake up groggy but after about 10-15 minutes the haze is lifted

    Comments about GNC Pro Performance® Zinc Magnesium Aspartate:

    You have to get this product if you are serious about lifting or working out at all. It helps me recover so much better and it helps me sleep through the night a lot better. I use to wake up throughout the night but since I've been taking this product I dont wake up till morning. Also I have had acne problems for a couple years now and since ive been taking this product my face has been clearing up.

      This product works great! It definitely promoted a solid sleep. I take this before bed with a casein shake. However, it smells terrible and upset my stomach a little bit which made it hard to fall asleep.

        • Good Value
        • Quickens Recovery Time

        Cons

          Best Uses

          • Before Bed

          Comments about GNC Pro Performance® Zinc Magnesium Aspartate:

          I take this product as prescribed: right before bed. I notice much deeper sleep, which is crucial for me as an Olympic weightlifter. I am currently deployed to Afghanistan and the days are long with no days off. When I work out, it's a relief but you also have to worry about recovery and the constant need to be "fresh" when you're preparing for tasks. This product helps me recover a lot faster by putting me in a deeper sleep. We all should know that you repair the most when you sleep and you produce the most testosterone while you're asleep. This product seems to compound the results that you would get from recovery exponentially. While there's never a substitute for getting your eight hours, I can sleep six while taking this and feel recovered. I strongly recommend this product to anyone.

            Good product. Have used before and will continue to use. The smell is horrible but I would rather have it smell than have extra ingredients that it doesn't need. Very good product for the price ! If you are serious about training you should have this in your regimen of supps.
