Standard adolescent conditioning ignores open growth plates and the specific metabolic demands of a developing body. Protocol B addresses both. It targets lean mass acquisition through controlled mechanical tension, manages endocrine variables by reversing catabolic states at precise intervals, and caps all training at 40 minutes to prevent cortisol accumulation. Macronutrient timing maps directly to glycogen depletion rates. The result is hypertrophic adaptation that does not compromise skeletal development. Output scales with calculated energy management, not volume.
