Try strapping on some ankle weights. Their good for around 20lbs. Now all you need to do is find another 10lbs and your sorted. You could wear steel toe cap boots, that might add a couple more pounds.
On a serious note, 30lbs of gains fresh of the starting block, and that you want to keep is pretty much impossibe. You could probably gain that weight but you won't keep it.
Take it steady and grow a little at a time and avoid all the mistakes by doing some proper research.
As a newbie you should definately steer well clear of Tren, Anadrol and Test Suspension. Also, keep of Winstrol (winny) until you know how other gear effects your hairline.
I'd do a low dose of Test E with some deca maybe and possibly throw in a little Anavar at the end to solidify your gains some what. Also, you need to know about post cycle therapy (pct) too which is an entirely different story but of equal importance.
Also, you need to increase you calorie consumption / calorific expenditure if you want lean gains without fat. Again, their is so much info on this topic that you could literally spend years reading about it. Do a google search for G-Flux and you will find some pretty good info on this.
