Bro, I was once a poor college student myself. I'm not sure what your lifestyle is, but if you wanna pack on some size on that tall frame, you must EAT, EAT, EAT, TRAIN, SLEEP. Also, believe me when I tell you this. Building muscles will be almost impossible for someone tht like to party and drinks excessively. Like I said, I was once a college student who wanted aq great body as well as wanted to party and live it up. It wasn't until I stopped partying adn drinking excessively and started living a lifestyle of proper nutrition, adequate rest for recuperation and training with the proper intensity that I began to pack on the muscle. You don't have to spend lots of money on supplements to add muscle. Food is the most anabolic substance there is. Eat lots of protein and drink tons of water. If you have the money for a supplement, I suggest creatine with some sort of transport system. This will cause you to hold a little water, which will serve several beneficial purposes as well as give you more endurance through ATP optimization. Good luck. Search these boards. All you need to know is somewhere here on these boards. There are lots of people here that have learned through trial and error and they know what works and what doesn't.
