Changes in Body Weight of Normal and Castrated Rats by Different Doses of Testosterone Propionate.

Abstract
Administra-tion of testosterone propionate above physiological levels inhibits body weight gain of normal and castrated young adult rats. Inhibition in the normal rat appears in doses above 25 ug/day and in castrated rats at above 100 ug/day. In the castrated rat inhibition is preceded by increase in rate of body weight gain. Food consumption of both normal and castrated rats varied with changes in body weight.
