I have used the QV Enath, Eq, and am currently running the Cyp. I have been very pleased with the results from all the products! It is a little early to really tell on the Cyp, its only been 3 weeks, but all other have been good.
Just be prepared for the fact that chances are instead of 10cc you will likely get 8 or 9 cc's. I have found alot of variance in their fill levels...
