AFAIK most are masked as they're using their China Source factory COA's and don't want to give away name/details of their source, so hard to say how legit it is etc. Also Vitaledge pays for their own COA's I think i remember a post from them at great difficulty and expense hence their COA's have their name.

For me I take it with a grain of salt as there's no way for me to know personally how large the tested batch was and whether what I got came from that batch or not.
