I'm curious -- are you coming at this from a weightlifting background? There's a lot of data and discussion in that field about how untrained people can gain LBM and raise their 1RMs and 5RMs quickly once they embark on a decent training program, and usually max out within a couple years without chemical help. Those metrics are at least somewhat easy to measure.
