lol dude drugs don't make you a better stronger person. Instead of doing that, you need to just work out at the gym. That's how real Navy guys like myself do it. I'm not in the military anymore, honorable discharge 2003, but when I was in submarines, in port we did an hour of strength training, such as pushups and situps, followed by an hour of running, about 8 miles. We did that at least three days a week, typically more than that.
Since I got out I'm way out of shape, I weigh 168 now, and I'm 5'7". Back when I was in submarines, I weighed 140.
