When juice is being referred to as underdosed, it means it tests out lower than what the producer
CLAIMS it to be per mg. So if QV bold is suppose to be 200 mg. per ml., and it tests out @ 180mg. per ml., it's then considered underdosed. British Dragon had a huge problem with this a couple of years ago. I heard they got their shit straight now.
For your info, you can check your QV gear lab results on their web page. All you have to do is look for your particular batch #.
One more thing, i never had acne breakouts until I started using QV. Now my back looks like I play goalie for the fucking dart team!
