So I just found out my best friend starting giving his 16 year old brother test prop yesterday. Needless to say when I found out, I was very disturbed by the situation. The kid is 6"5" and weighs 165 lbs. His dad is also aware of what he is doing as well. Now Ive tried convincing my friend that its a terrible idea. Telling him all the bad things that can possibly happen and why its a terrible idea, but he is stubborn and hard headed and wont listen to me. Ive tried explaining to him that he doesnt know how to eat, but he said Im telling him what to eat, but my friend doesnt even know how to properly eat. Hell its taken me years to learn how to eat to build muscle properly. I get the same bullshit excuse, that he eats all the time and cant put on weight and all the other kids in high school are taking them. Yeah I know the kid eats all the time, but he eats like all 16 year old kids..snacks and junk food. Doesnt eat high quality protein, carbs and veggies nearly like he should. His dad asked me a while back about putting his son on something more "mild" than test, aka winny and I convinced him that it was a bad idea and told him to work on teaching him how to eat properly and he agreed. Ive even offered to write him a diet. Im thinking Im gonna have to talk to his dad again about this. This is really bothering me right now especially since Im best man in my friends wedding next month. I know all the reasons why its a terrible idea, but my friend wont listen. Im looking for any type of suggestions or new ways to approach this situation. thanks guys
