Stavios I dont blame you man, you have an awesome physique and your a pretty good looking guy, to be honest, I would stay lean but lose a lil' muscle and do some modeling. Atleast with that you'll make some money and wont put your body through the rigors that you currently are with your drug regimine at a ripe age of 19. In the end, I doubt the drugs you put in your body was worth a 4th place finish.
I think you have an awesome physique too. And dude, u dont need validation that you have a good physique from a bunch of schmoes and pedophiles who were in the audience at the show you did. The months of hardwork you put in dieting and the sweat you dropped in the gym is plenty. Who gives a fuck is u placed fourth. You brought your body to a place where it has never gone before. Congrats dude.
