Some of it is reversible, I'm sure you've seen guys drop the roids and suddenly look younger somehow. The face has muscle too and then there's the water.
Sometimes some geezer gets on "HRT" and suddenly looks more youthful with more "vitality" so it depends. GH is supposed to thicken the skin which gets thinner with age.
Guys probably look better with some gear than without, depends on your subjective preferences. Gear causes what I would call the anti-K-pop effect. Now those guys look freaky in a very bad way. What kind of culture likes this for peak male? It's disgusting to me, like looking at worms.
