I havenot heard one negative thing about QV as of yet. It makes sense too. A new company trying to make a name for itself isn't going to put out a crappy product. The chance of counterfiets is slim due to the fact that it is a fairly new line.
I have only been hearing good things. I just got a vial of QV EQ that I am throwing in in place of the TT just to try it. I did order the 50ml Enth and the 50ml Deca fro next cycle. I have never been a big Mex guy and the majority of my cycles are euro prods with a few mex stuff thrown in but I think I'm gonna run an all Mex cycle next. (With some T400 thrown in) I don't know about the mex orals though I'll probable stick with euro stuff in that regard. I stil have plenty. I will also bring my Fina Kit to Taco Bell several time before making it just for that Mexican feeling. (If it's not too crowded I might just make it right there. And maybe pre-filter with a chalupa.
