I am two weeks into an QV Enan cycle right now. I'm alternating between ass cheaks, the first few doses are a bitch. REALLY killed me. After the first few sticks, the qv doesn't hurt that bad any more... No idea how long it takes to see results from this stuff. I am hitting 500mg/wk split into two 250mg doses tuesdays and fridays. I have heard rave reviews about it though, and as my first cycle I am expecting a lot from it. Good luck bro.
