Highlanda did I know you were a Marine Corps Officer? Congrats, I'm a Corpsman
My opinion - NO, he should not do any PH/steroids before school. I am a Navy Corpsman and am currently training for and dropping a package to go with Marine Recon. I have some experience with this kind of stuff just to let you know.
It will only hinder his chances for these reasons...
- Medical side effects combined with the kind of physical stress from school will be a very very bad thing!
- The more muscle mass you have the more oxygen it requires making running more difficult and Ranger school will be Sh*t ton of running...I promise.
- He won't be able to use his extra weight to feed off of long enough anyways.
- They are most certainly not going to allow him to take supps during school other that a multi vitamin, protien, and vitamin C. At least that's the way it is with BUD/s and recon, even creatine is banned in those schools so he may not be able to complete a PCT.
What he does want to do...
- Eat healthy, but not be so concerned about a six pack
- Crossfit like a mofo...all the the SF guys swear by it, Recon, SEALs, SF, etc. It's far more functional than "bodybuilding"
- Get a good running regimen going
- Swim, a lot
- Scale back training as school approaches, you do NOT want to over train. Does you no good to show up with stress fractures.
- Strength, Stamina, and endurance are what count not size!
The guys who make it through these kinds of schools more often than not have a triathlon type body etc. and not the bodybuilder type.
Bottom line if he is in shape then 5'11 161lbs won't matter and as long as he doesn't quit he'll be straight.
Best of luck to your buddy
