Here is the problem with UGL's; you wont ever know if it is under-dosed or not! The only way to have certain consistency is to get a script or make it yourself. That being said, I brewed for a gang of Russians one time; they told me that
I better be damn sure that it was doses over 300 mg/ml, period. They sent me exactly what I was supposed to fit and I did it. There are some UGL's that are legit and I really feel like you can do well with some of them. You need to just pick and choose wisely. I have had some good times over the years but the best times are the ones I did myself. I know exactly how clean the area was, I know exactly what is in there as well, I have never had a problem internally from mine own. Just a thought for you
