Hi,
So I'm 16yrs old, 170lbs, 76 inches tall (slim build) and need advice for bulking-up. I currently workout for approximately an hour 5 days a week. I started about a year ago, and have seen pretty good results.My workouts include many exercises on different days (upper body, lower body, core, cardio). I've gained about 20lbs, and 2 inches of height in this one year period. I've tried protein drinks and creatine, off and on.

Am I off to a good start?

Should I be taking any other supplements, or increase use?

Opinions please

Thanks
