So are you saying the blends are usually underdosed ?
And even not what they are supposed to be? Did wonder if it is really possible to get anything that is truely 450 per ml? Anything over 250 has got to be suspect don't you think?? 
Very hard for a real pharma to get accurate doses like that let alone UG. Higher doses of single product is easier and more likely to be accurately dosed. These blends of 50mg, 75, 125mg all mixed up are usually incorrect. Someone here posted how concentrated each product would have to be to be accurately dosed but I can't remember where and who. Unless you know the person making the stuff (or are making it yourself) it's unlikely to be correct.
I.e.
Remember that if they are saying you are getting 200 equipoise and 250 test in 1ml the test would have to be like 500mg/ml and the equipoise 400mg/ml. (roughly) There are other factors to consider with the oil being used etc.
