The mp3 version of hand of god here http://sites.fastspring.com/idoser/product/mp3
and the .drg version here http://www.i-doser.com/store
are completely different versions. The pure .drg file is a more complete sequence. The mp3 is shorter and with ambient backtracks and different programming. People find the .drg to be exponentially stronger, and it was always intended to be a premium developer dose (not in wide release) which is why it is priced so high.
Oh, and if you downloaded any HoG version from a torrent and alternate site other than I-Doser - its a fake. It is our most counterfeited dose. Every instance posted instance not from our dose store has been a fake. We did a test where we downloaded 50 instances of HoG from various torrent and download sites and every single one was a fake.
