Um... There's like 12 different sources with dragon in the name.
If you're asking if dragon pharma is a good brand... Yes! I've probably used more dragon brand gear than any other brand out there.
I've used there test e, test c, tren ace, tren e, mast e, mast p, deca, multiple blends, accutane and other orals. Always top notch stuff.
As far as your source... I can't say from lack of information
