The rock hard is a better product

You're buying a supplement so they only work if you believe they will work.

I like the results

My energy level improved

It's a semi-large pill but it works great. Not really that strong, but I prefer it that way. If you are tired, it definitely will keep you awake. Which is all I need for the ride back from work as I always feel tired then
