Obviously nothing like my newbie gains, but i consider those absolutely rediculous. I went from 145 to 185 in about 5-6 months when i started working out at 16 or 17. After that i pretty much stopped and dropped to about 170 because of all the cardio from basketball, took a few years off, working out here and there but always hovered around the 175-180 mark.
I'm 22 now and have been working out fairly consistantly for the last 2 months and I'm about 200 now. I'd say about 10 of that is probably creatine water weight but whatever, my friends and family have all commented that I've gotten bigger (I'm still a fucking stick but again, whatever, at least I'm growing).
My diet is fucking garbage, i don't eat enough to grow properly, but I'm working on it. I find that I grow pretty easily and whenever i stop drinking and partying all the time it's pretty easy to put on the lbs but the hardest part has been avoiding the drinking and partying.
Anyways, hopefully I'll continue to grow and hit 210 before Christmas and 220 by next summer. I doubt i'll stay natural forever but untill I'm confident that my diet, sleep, and workouts (that's the easy part) are 110% in check I don't deserve the needle.
