I don't know if it works or not, but I seem to have more endurance when i am taking it.

I don't know if it works or not, but I seem to have more endurance when I am taking it. Even if it is all in my head if I feel stronger, I'll take it.

It is a bit pricey for a subjective perceived benefit.

Improved recovery time

Used for a couple of years after reading a positive review by a medical professional who was taking it himself. I cannot claim any better performance, but I do believe that my recovery time after intense or endurance events was much improved. Ultimately I stopped taking this as this expense is so high.
