no, they are not just as good as pharm. grade brands. In fact, UG labs vary so greatly that it's impossible to tell what's what. For example, HC labs tested at 243mgs on a 400mg product, so you know there is a problem. Currently, there are 2 types of UGs: 1) ran out of moms-basement, small timer, usually means well 2) larger lab set-up , still a UG, but more likely to be better quality then 1 (not always)
I don't really trust either, but the 2nd option seems to pan out a lot more then the 1st.
You just have to find a reliable one...I only use UG because I know I have a good one gear is always as advertised and is always a lot cheaper than brand names...do some research and you will find what you want
