This is a placebo-controlled, double-blind, parallel, Randomized Controlled Trial of 6 months
of Growth Hormone Replacement Therapy (GHRT) vs. placebo in Veterans with a history of Gulf
War Illness (GWI) and Adult Growth Hormone Deficiency (AGHD). The investigators hypothesize
that GHRT will reduce truncal fat mass percentage measured by DEXA (primary outcome). This
could provide those veterans with GWI and AGHD a novel therapeutic option (GHRT). The study
will also examine the feasibility and safety of a larger efficacy trial.
