Bootstrap Analysis to Determine Changes in Testosterone Levels Necessary to Augment Lean Mass

	Total LBM Target = 1.5 kg	ASMM Target = 0.8 kg
Change in testosterone (T) alone, ng/dL, N = 39	1046* (1040–1051)†	898 (892–904)
Change in T with any dose of rhGH, N = 73	944 (938–949)	912 (906–919)
p Value	<.0001	.002
Change in free testosterone alone, pg/mL, N = 38	477 (474–480)	397 (394–399)
Change in free T with any dose of rhGH, N = 72	303 (301–304)	275 (273–276)
p Value	<.0001	<.0001

Notes: ASMM = appendicular skeletal muscle mass; LBM = lean body mass.
