Steroids are like plastic surgery. You get the freaks who overuse it to the point that actually make themselves considerably less attractive, but then you have the people who aren't mentally ill, but are willing to take advantage, sensibly, and those people tend to appear pretty fuckable into their 60's.
There's no shortcut that outshines the basics. People who eat well, exercise moderately and consistently throughout their lives, sleep well, keep their stress levels low, don't do drugs legal or otherwise, manage their health (including dental), don't endure withering jobs that expose them to the elements, and perform the upkeep of grooming just flat out age better than everyone else. Genetics is huge, sure, but the tortoises win this marathon pretty much every time.
