You can take creatine / nitrous oxide mixture and drink protein shakes. Creatine May Be ware you get to break with acne. The best way winning is all in how you work and, more importantly CONSISTENCY, 3-4x / week for 45 minutes you need a workout power and perhaps you should consult a personal trainer who can make a good program for you with this schedule. Supplements are not a quick / easy to win, work hard in the old and time in the gym beats all supplements. Stay away from roids they will remain but to destroy your body.
