Keep in mind, Red was made from the original's comatose self. That means Cadmus probably had lot more to work with. Let's face it, how good a sample could they really have snatched from Superman? I know there was the whole supergirl/galatea thing in JLU, but really I don't think Superman's DNA is just that freakin' easy to come across. With Speedy/Red they had a constant supply of fresh DNA to work with 'cause they had the original on hand the whole time. Biological samples don't keep forever, and honestly I don't think they could have gotten a very good sample of Superman's DNA in the first place. So maybe they missed something in translation, or his kryptonian DNA is keepin' him young, or maybe he just doesn't age that much. I look about the same now as I did six or seven years ago in middle school, and I'm 100% human to the best of my knowledge. Some people just don't visibly age that much.
