I've gone from 60kg-64kg in 6 weeks. I'm pretty happy with myself, going to keep bulking for another 6 weeks and hopefully hit 68kg. I could probably increase my calorie intake and get quicker gains but I'm happy with the progress.
It's amazing the responses you get from people when you tell them your trying to put on weight,,, "Why don't you just eat mcdonalds" "isn't putting on weight unhealthy" blah blah blah
