If you're talking about DMC, I've done both blood & aquarium tests & it's definitely real. But obviously I haven't used it yet
So I can help on that front.
But no, I won't give out the source as I was asked not to. We had lengthy chats because of how shit I am at this, so a lot of long back & forths - at one point I was asked not to give out the details on this particular site - maybe they thought I was a journo because I asked so many questions??? I doubt normal people on this site been asked not to share, normal people would've probably just ordered & received, instead of crazy in the middle of the night anxiety ridden WhatsApp's.
