Oleoyl-estrone
Oleoyl-estrone (OE) is a fatty acid ester of estrone. This hormone occurs naturally and is found circulating in various animal species and humans. It has been shown in animal studies to promote the loss of body fat while maintaining body protein storage, maintaining nitrogen balance.  Body protein loss is an unpleasant effect of fat loss by the restriction of calories, and studies show that this drug appears to avoid this effect.
