In retrospect I wish I had tried the GXR a little earlier in the experiment to give it more time to see how it would have worked. Also the Durablast may have worked better stacked with another energy booster.

I really like Marc and the Scivation/Primaforce products a lot and I wish I could give Durablast my seal of approval, but I was not real impressed with it. I won't be buying it, but fear not Marc, I will still be buying a lot of your other products.
Thank you for the HONEST review.
