Can someone be THIS STRONG at 22 ?!?!

I am in 11th grade and my physical education teacher says he used to bench 140kg (his shoulder got hurt so couldnt train more) , squat 240kg and deadlifted 260kg.

And yeah, all of this in 3 months in his university gym. (he doesnt admit to taking anabolics)

IS it possible for a 22yr old weighing less than 80kg to acheive these SBD standards?

the only reason i think he aint lying is bcz the guy is built like a tank. He has those HUGE ass legs, even though he is not training.

do u know anyone who is this strong?
