Sources of Environmental Exposure to the Naturally Occurring Anabolic Steroid Ecdysterone in Horses

open access: yes
Ecdysterone controls moulting and reproduction in insects, crustaceans, and helminths. It is also produced by many plants, probably as an insect deterrent. The steroid is not made by vertebrates but has anabolic effects in mammals and could be useful for
