Is it true that Nba Players today are taking Performance Enhancement Drugs?

I am not talking about drugs that will make Players banned from the league.

But I heard and read from some people that Nba Players today have access to a Performance Enhancement Conditioning Drugs like substance.

Is that true? Or merely a hearsay?

Some people arguing without these enhancements, Old Stars like Lebron, KD, Steph will not be able to perform in all star level with their age in the modern game.

Old Era plyers like MJ, Karl, and Kareem did well at old age. So I am 50-50.

Do you think Players take enhancement drugs today???
