well, considering i was a weakling when i first began, i guess you could say a substantial amount. Then again, i never really forced myself to lift heavy from the beginning because i was very good at the lifts and just tried to get the form down early on. But just as an example, when i started out, i was pushing 95 pounds on the bench lol, but i gained alot of strength fast, and not i've been stuck at the same poundages for a long time. Btw, i use protein all the time, and cycle on and off creatine. The reason i am doing a cutting cycle is because i want to shed some more body so i will beable to preform a cleaner bulk and still remain relatively lean by the end of it.
Size wise, i've done ok for myself...i've eatin like a pig during my bulks... but it doesn't show in my lifts and its kind of embarrasing.
