A simple test for dianabol is to pour some car battery acid and see if it turns brown-red.
Dbol and anadrol have characteristic taste when chewed, however takes some experience to recognize.
Its better to learn to spot fakes, amps are much less faked than vials, amps lettering must be sharp, perfectly aligned. Vials must have well printed, full color labels, altough labels sometimes are out of alignment.
Best if sent with the box and paperwork.
Tabs are hard to crush, with well made borders.
I have lost my ability to spot fakes, since im living in latin america for business reasons. Or who knows? maybe since i see so many legit gear, will spot a fake easily...
