How strong is He-Man?

Is he really the most powerful man in the universe?...

i saw a episode where he closed a canyon with his strength, he fixed a broken chain with his bare strength, he is so strong he can break the rules of physics

he pushed the moon once

A fake Superman tossed him around for a while until he stabbed him

He-Man = Silver Age Superman, at least in the 80s cartoon he did. Every version is different.

I believe they said in the show that he draws on the power of Greyskull to be as strong as he needs to be. So he is potentially infinitely strong, and if there is a limit to his strength it hasn't been shown before.

Probably in his universe, cause his got the power.
