I am 28 years old, and started working out when I was 18. I went from around 115lbs, to around 172lbs now, at 5' 10". I was watching some videos on youtube, and a few guys were saying one can naturally gain 20 to 40lbs of muscle naturally, and then you are stuck. If that is true for all people, then it sounds like I am stuck (according to the "consensus"). When I look at myself in the mirror, I dont look like I am at a natural genetic potential, so to hear I could be at a genetic cap is discouraging lol. Have any of you gained beyond 40lbs of muscle being natural, or before starting AAS? I dabbled with AAS when I was younger, and wont mess with it until I need TRT when I am older. I personally do not want to be at a genetic limit.
