I guess i should introduce myself...im a College Student from Texas.  I weigh 160lbs and im 5'8'' tall.  I'm in pretty good shape...low body fat...good development of muscle groups..eat healthy...all that.  For over a year now I've been trying to put on some muscle get that whole...pumped look.  You know...veins popin...muscles bulging...strong look.  I've had no luck...I've tried all kinds of muscle building routines...cut back on my cardio...diets...but I can't seem to get any real gains.  I've seen people start out looking much like myself, and within 1 month to 6 weeks...WoW...totall transformation.  They didn't get freakishly huge or anything...just looked more solid and pumped.  Bottom line is...how do i get that?  I appreciate any imput.

you mean 1 month to 6 months I guess?
