If sust don't start kicking in around 4 weeks, how could he put on 10 pounds by now? Also how does your physique look? I just started my 4th week of Infar sust at 500mg /week, and I gained about 4 pounds. But I can notice the difference when I look in the mirror. I consume about 4000 cal.s per day and about 200-220 grams of protein. What kind of sust are you using?
