bro i can tell you through personal experience, that its so hard to determine a fake ampule of sustanon made by organon, i have had hundreds and hundreds of them, and many looked very different but were good, the fake looking ones were the best and the best looking real ones were fake, and they make so many different looking ones it is hard to tell, and counterfeit sustanon 250 is still good, its just not real organon, lol, fake is no good at all but counterfeit is usually fine, crazy i know
