its all in what you eat and your work ethic bro.....
my first cycle i ate like a pig, 300g protein, maybe more...just ate and ate and ate.....coming off my bulker food almost made me sick...Realistically you can expect to put on about 15lbs, providing that you are not close to your genetic limit...if you train appropriatly and maintain a healthy diet, you should be able to keep 85%+ of your strength gains....
