Do you think these kids juice?

I met 2 kids at my gym that are 16 one benches 225x8(kidA) and the other 405 1 rep max(kidB).Do you think they juice? If so kid a or b or both?

The first one probably not as I could do that when I was 16 naturally. But the second one is a red flag for sure it is highly unlikely to attain a 405lb bench naturally at 16 years old. Who cares though really.

They are probably on the M-1-T diet like all the youngsters at my gym.

to many bio-mechanical advantages to tell.

at 16 i could bench 225 for 15 reps and had teamates who could do it for 20-25 and we were all natural. 405 is a little iffy though.

I know someone who benched 405 the first time he laid under a bar. got to 685 w/o a shirt in 4 years of training. he had every bio-mechanical advantage. %'tage of fast twich to slow, tie-ins,...etc.
cant say w/o knowing more about their advantages

and dont forget short arms and a big puffy chest !!
