Is there any way to shrink a superhero compression tee?

I bought a superhero comp tee in a size large and it fits good especially with a pump but it's a bit too large around the bottom and it's more of a baggier look. I'm used to wearing under armour comp shirts that fit me snugly. So is there any way to get my superhero to get little smaller on the bottom, I used hot water for cotton shirts but I have no idea if the yla material will behave the same, thanks.
