Ok well if your in Germany, like I was....Your best bet is to find them off post, since its fairly easy. If not, you shouldnt really have any issues, unless the company you get it from won't ship to an APO address. Also under UCMJ Article 112 the use of these products is punishible, but they rarely test unless they suspect it. Also, at 19 you should probably look into natural products, and stay away from the chow hall. Buy as much food as you can store in your barracks room and make food. We had a community kitchen in our barracks so it was fairly easy to cook there
