I am not sold on Maslinic acid at all.
And being "anabolic", well if you are fish so..

Abstract
Maslinic acid*is a triterpene present in a considerable proportion in solid residues from olive-oil production. In the present work the effects of*maslinic acid*on growth, protein-turnover rates and nucleic-acid concentration on liver were investigated in the rainbow trout. Five groups of 120 fish of a mean body mass of 20 g were fed for 225 days with diets containing 0, 1, 5, 25 and 250 mg of*maslinic acidper kg diet. At the end of the experiment, whole-body and liver weight and growth rate of trout fed with*maslinic acid*were higher than controls. The highest weight increase was registered for the group fed 250 mg kg(-1), representing a 29% increase over controls. The total hepatic DNA or liver cell hyperplasia levels in trout fed with 25 and 250 mg of*maslinic acid*kg(-1) were 37% and 68% higher than controls. Also in these same groups of trout, fractional and absolute hepatic protein-synthesis rates were significantly higher than in control, and significant increments in hepatic protein-synthesis efficiency and protein-synthesis capacity were reported. In close agreement with these results, microscopy studies showed that trout fed on 25 and 250 mg kg(-1) hepatocytes appeared to be more compact, with a larger rough-endoplasmic reticulum and larger glycogen stores than controls. These results suggest that*maslinic acid*can act as a growth factor when added to trout diet.
