title: Changes in body composition following therapy of osteoporosis with methandrostenolone.
abstract: A two compartment, double-blind, randomized, parallel study was performed comparing methandrostenolone with placebo in the treatment of osteoporosis. The duration of the study was 24 mo. Dependent parameters included total body calcium (TBCa), measured by neutron activation analysis: bone mineral content of the radius (BMC), measured by photon absorptiometry; and total body potassium (TBK), measured by total body counting. A significant increase in TBK occurred in the treated group, primarily in the first 6 mo; thereafter the TBK remained fairly constant. No significant changes in bone mass occurred, except the 6 mo TBCa measurement increased by 11 grams for the methandrostenolone group and decreased by 6 grams for the placebo group (p = .05). Other evidence also suggests that anabolic steroids may not produce sustained uncoupling of bone formation and bone resorption in osteoporosis. If methandrostenolone is capable of producing an increment in bone mass in osteoporosis, it was not readily observable with the sensitivity of the techniques employed in this study
