That is true however that isn't an enhancement. Hell there are other supplements that you can take that do exactly what steroids do but they are legal. They may not be on the same level sure but they still reduce recovery time and help you lift more for longer.
I think it truly comes down to genetics more so than anything else. If you have good genes vs someone who doesn't and say both people use the same supplements the person with good genes will still out perform the other person. So with how the world is going I wouldn't be surprised to see people wanting to ban people bc they have "unfair genes" lol
