Thanks for posting, lots of people here to help. Based on your pics and experience, I don't think you're ready for the iBodybuilder program. You'd need a lot more mass and time under the bar to make the most out of that program. The best thing to do would be to get on a solid bodybuilding template, and follow a nutrition plan that will allow you to gain as much LBM as possible without overdoing it, and do this for at LEAST 6 months, and take it from there. Here's exactly what you should do:

Before your workout, eat a Finibar or have one scoop of Plazma. You don't need to worry about pulsing or other supplements at this time.
Don't overthink it, construct a good plan using the article, get your nutrition in line and be consistent. Be sure to post back with any questions!
