Denkall var is good stuff. Its right up there with btg's. QV var is okay but don't let the lab results fool you. Whenever a new product is introduced its always in their best interest to overdose the product. Considering QV's track record I highly doubt var tabs are still consistently overdosed.
By the way, I ran 8 weeks of var at 20mgs ed and loved the results. I used it for modest strength gains and to help preserve muscle mass as I was dieting down. If your plans are to bulk up or put on weight, 30-40mgs is a good dose.
Good Luck,
